Remote start disabled P0521

I have a P0521 that goes and comes. Started about 2 months ago, swapped It out with a Advance auto one code went away for 3 weeks then came back. Swapped It again and the code came back the next day and started to puke oil between the sensor and electrical connector. So I had no choice but to put the original sensor back on. Installed a new a OEM AC Delco sensor and also replaced the screen under the sensor (dorman) and the code disappeared for a few days and came back. Now the code has been gone for about 2 and a half weeks and this morning we got a little snow storm and the car has been off for about 17 hours In the cold snow. I remote started It and listened to It start up cranked weak but started and the engine sounded fine no lifter noise. It ran 10 minutes and shut Itself off. I started It up again and within 10 seconds I heard It shut off. Went out and manually started It and the engine light Is on with P0521. I'm at a lost here. I always let It warm up before taking off.

Yeah as soon as you have a check engine light it will disable the remote start, this page has some troubleshooting information on it that might help.

What's the oil level? The LS4 5.3L has a reputation for using oil.
Did you change the engine oil and filter when you changed the sensor and AFM filter?
Are you using decent 5W30 or 0W30 Synthetic motor oil?
Preferably you want 0W30 with the present foul cold winter weather the Northern states. You can get Mobil 1 0W30 five quart jugs at WalMart for right around $27.
Get a Synthetic media filter like WIX 57060XP or AC Delco UPF48R. They're less than $10.

Did you look over the wiring to the sensor for damage and is the plug in good shape?

If all of that is good and it's still setting a MIL check the actual oil pressure with a mechanical gauge screwed into the sensor hole.
The LS engines, like our LS4, have a reputation for the oil pickup tube seal failing. If it's slightly low you can probably bump the oil pressure back up by changing the oil pump pickup screen O-Ring. I'd change the oil pump too once you dig into it that far...
If you're pulling the pan to do the oil pump pickup and oil pump be sure to get the updated oil pan gasket in TSB 11-06-01-007 to deal with the AFM oil consumption.

This is the GM LS4 Oil Consumption TSB thread on LS1Tech... https://ls1tech.com/forums/ls4-perfo...l-fix-ls4.html

#11-06-01-007 : Engine Oil Consumption with Active Fuel Management (AFM) (Install Oil Pan Gasket and Clean Carbon from Cylinder) - (Nov 22, 2011)
Subject: Engine Oil Consumption with Active Fuel Management (AFM) (Install Oil Pan Gasket and Clean Carbon from Cylinder)

Models: 2008-2009 Buick LaCrosse/Allure
2006-2007 Chevrolet Monte Carlo
2006-2009 Chevrolet Impala SS
2005-2008 Pontiac Grand Prix GXP
Equipped with V8 Engine RPO LS4

Condition

Some customers may comment about engine oil consumption of vehicles with higher mileage (approximately 48,000 to 64,000 km (30,000 to 40,000 mi). Verify that the induction system is assembled correctly and that there is no evidence that the engine has been ingesting dirty air due to a mis-assembled induction system. Also verify that the PCV system is functioning properly. If diagnostic procedures indicate that oil consumption is piston/piston ring related, verify that oil consumption is greater than 0.946 L (1 qt) in 3,200 km (2000 mi). If these conditions are met and oil consumption is greater than 0.946 L (1 qt) in 3,200 km (2000 mi), perform the service indicated in this bulletin.
Cause

This condition may be caused by oil spray that is discharged from the AFM pressure relief valve within the crankcase. Under most driving conditions and drive cycles, the discharged oil does not cause a problem. Under certain drive cycles (extended high engine speed operation), in combination with parts at the high end of their tolerance specification, the oil spray quantity may be more than usual, resulting in excessive deposit formation in the piston ring grooves, causing increased oil consumption.

To correct this condition, perform the piston cleaning procedure as described in this document, and install the new oil pan gasket per the procedure outlined in this document. Monitor oil consumption after this repair to ensure oil consumption has improved to acceptable levels.

If this repair does not correct the condition, it may be necessary to replace the piston assemblies (piston and rings) with new parts.
Correction
A new oil pan gasket has been released. Technicians should replace the oil pan gasket with GM P/N 12643081. This oil pan gasket has the AFM shield incorporated into the gasket. Refer to SI for Oil Pan Gasket Replacement.

To correct this condition, perform the piston cleaning procedure as described in this document, and install the new oil pan gasket per the procedure outlined in this document. Monitor oil consumption after this repair to ensure oil consumption has improved to acceptable levels.

If this repair does not correct the condition, it may be necessary to replace all of the piston assemblies (piston and rings) with new parts. Refer to SI for repair procedure.
Important: It is critical in this cleaning process that the engine/fuel injector cleaner remain in the cylinders for a minimum of 2.5 hours to fully clean the components. The cleaner solution must be removed before a maximum of three hours.

1. Verify the oil consumption concern following Corporate Bulletin Number 01-06-01-011G. If oil consumption is found, continue on with this bulletin.
2. Remove the spark plugs and ensure that none of the pistons are at top dead center (TDC).
3. Clean the pistons by putting 118-147 ml (4-5 oz) of Upper Engine and Fuel Injector Cleaner, GM P/N 88861802 (in Canada, use 88861804), in each cylinder. Allow the material to soak for at least 2.5-3.0 hours, but no more than three hours and then remove the cleaner. A suggested method of removing the cleaner is cranking engine over. Make sure to unplug the ignition coils and fuel injector before cranking the engine over. Also make sure that the painted surfaces are covered so no damage is done.
4. Remove the oil pan. Refer to Oil Pan Replacement in SI.
Important: Ensure that the engine cleaner is thoroughly removed before reinstalling the spark plugs. Failure to do so may result in a hydro-lock condition.
5. Reinstall the spark plugs. Replace the spark plugs if necessary due to full of carbon. Refer to the parts catalog.
6. Reinstall the oil pan. Refer to the Oil Pan Installation procedure in SI. Replace the oil pan gasket.
7. Re-evaluate the oil consumption. Document on the repair order. If the oil consumption is still greater than 0.946 L (1 qt) in 3,200 km (2000 mi), replacement of the pistons and rings will be required.
Important: Some minor scratches may be noticed on the cylinder walls during piston and ring replacement. If the scratch cannot be felt when running your finger nail over it, the scratch is considered normal wear and the block or engine should not be replaced.


Note: It is not necessary to hone or deglaze the cylinder walls. Honing may induce unnecessary cylinder wall and / or piston ring damage if it is done incorrectly and/or not cleaned thoroughly. Cylinder walls should cleaned thoroughly with brake cleaner before installation of the new pistons and rings. Numerous engines replaced for oil consumption have been inspected. The cross hatch has been consistently good and is in specification. As a result, is should not be necessary to measure the cylinders if they pass the visual inspection.

Parts Information

Part Number: 12643081 Oil Pan Gasket
Part Number: 88861802 (in Canada, use 88861804) CLEANER, F/INJR 16 OZ LIQUID POUR (Upper Engine and Fuel Injector Cleaner)

No It doesn't burn oil. I changed It last with Castrol Edge Full Synthetic 5w30 and It's down to 77% and It's only dropped one dot on the dipstick. I took the sensor and little filter out again and cleaned them up real good and tightened It a tad bit more and made sure the connector was tight. Before I left work I remote started It and It shut off after a few minutes but started back up and Immediately shut back down. Code Is pending but not confirmed. I also took the valve cover off to check for sludge and the engine Is spotless.

It sounds like it's time to put a mechanical gauge on it and see whta's really going on.

As I said the LS engines have a reputation for the pickup tube O-Ring seal going bad.
If you're over 100,000 miles I would change the oil pump too.
The reason I posted that TSB is it includes the part number for the updated pan gasket. If you aren't burning oil it's still a good idea to put that gasket on.

Yeah unless I get the "low oil pressure stop engine" message I'll wait until It warms up to get under there. But I will hook up a mechanical gauge and check. But the problem Is Intermtinant. Like this morning It was -9F and the car sat outside all night. I remote started It for the full 20 minutes and It ran the whole time without Issue.

I read that people with the 5.3 and AFM/DOD In Silverados were also getting this same code. And GM released a TSB about and there solution was the high performance oil filter UPF48R I ordered one a week ago just havent Installed It because I see no difference In the current Mobil 1 filter I have now. I was thinking of switching back to the K&N filter with I believe 12 holes vs 6. Because the code didn't appear until I started using Mobil 1 filters. I don't know If there bypass valve Is different and that's causing the problem, or what. Guess It's worth a shot.

Another thing I see people saying Is trash/debris In the little sensor hole/filter. Everytime I take the pressure sensor out I'm clearing alot of debris out. It's hard to get anything down there that will clean It out.

Ok little update. Two days ago I removed the pressure sensor and little filter and Installed just the sensor leaving the filter out. Everything worked as normal AFM had no problems. Before I left home this morning It ran the full 20 minutes on remote start. Then when I was leaving work I started It and It ran for 5 minutes and shut off. Code came back. So today I switched oil filters to the one GM recommends and they claim It remedies the P0521 on the 5.3's. UPF48R Is the performance filter they recommend. So I will update If It comes back on.

Here's the BITOG thread on this...
https://www.bobistheoilguy.com/forum...trucks_losing_
There seem to be two camps. One says it's the pickup tube O-ring and the other claims it's the filter.
My knee jerk guess is the O-Ring.
I may get to do two of them this summer. My 09 SS was ticking when I woke her up for her mid-winter startup even tho the garage was warmed up to 50F for several hours and my 05 Silverado with the LQ4 6.0 is ticking cold and running around 25psi hot idle oil pressure.

The LQ4 will get a new oil pump but the LS4 is only getting a pan gasket and O-Ring.

Yeah I'm not worried. I know It has oil pressure so I will tackle that this summer. But I am gonna switch back to the K&N oil filter as I said that code didn't appear until I switched to Mobil 1. Thanks for your help I really appreciate It.

Ok bringing this back. I got my Superchips tuner and haven't Installed the tune yet but I've been watching the gauges on It specifically oil pressure. On cold starts when Idling It has around 10-20 PSI Idling. If I rev It up It shoots up to 40-50. After driving It a little It will maintain 40 PSI at Idle and maxes out around 55 PSI at 5000 RPM. So I see why It shuts down when cold and I see why the code never appears when the engine warms up because It only happens when It's cold out. This morning when I started It I literally counted It going from 0-20 PSI. Can you replace the oil pumps oring by just dropping the pan? Thanks.

Put that screen back in. If it's catching crud it's keeping that stuff out of your lifters. 5.3L lifters are fragile enough without extra help from chunks of crud.

This spring won't be a fun time in my garage. Two LS oil pan drops. WalMart has Mobil1 and Castrol

0W30 motor oil will help the low temp low pressure somewhat... even with a cracked oil pickup seal ring.

Ok so looks like you can by just dropping the pan. Cause I'm certainly not taking that timing cover off. But I only ran without the little filter for a day before It threw the code again and I put It back In. When I did the first oil change on It last year I used Mobil1 0w30 but ever since then I can't find It anywhere. I'm due for a oil change as It's down to 29% and I've never let It get down that low before. So If I can find some 0w30 I'll switch back. But on our 5.3's, dropping the oil pan looks very easy as we don't have a differential or steering components In the way. But thanks.

Been really cold here the past few days. Was 9 degrees this morning and I remote started It and came out to It ticking quite loudly and I Immediately pushed the button to shut It off. Got In and pulled up oil pressure on the tuner and started It back up and It didn't even have 10 PSI. Idling up to 2k brought It to normal pressure. The ticking didn't go away until I actually drove away, revving In park did nothing for the ticking. I'm hoping the ticking was the heads as the bottom end gets oil first. As I was about to pull out It started losing pressure again dropping below 10 and I shut It down until cars passed and when I started driving It was fine. Why did It not shut down, Idk. But I'm questioning could It possibly be the oil pump? When I started driving I pulled over up the street and let It Idle and It had 40+ PSI Idling and the engine was still cold. It's just that Initial cold start when It doesn't have any. Thanks.
