I have codes p0097 p0641 p11c2 p2199 on my 2012 Verano. I already replaced the mass flow air sensor with a new OEM GM one off Amazon. I also replaced the High pressure fuel pump.

What led me to think it was fuel-related was when the car first wouldn't start I had the codes p0089 and p228D. These codes haven't returned, cause I think the car just doesn't run long enough for them to return.

These codes were also on the very first time I scanned the car....... Cam related codes p0340 , p0341 , p035 , p0366

then a bad cat code p0420 and a evap leak code p0442

The codes that are coming back instantly after clearing them all are p0097 p0641 p11c2 p2199. These point to a mass-flow sensor but I tried a new OEM one. IAT sensor 2 reads -40 , sensor 1 reads 73.

Has anyone else experienced this where the car wants to start but shuts off right away? I think the timing chain is loose but I wanna check all options before i take a peek in there. Thank you

Cam/Crank sensors are very common failure items, with most vehicles have are often replaced as a PM item in the 80K to 100K range. EVAP leak could be as simple as a bad gas cap. Catalysts could be bad CATS or bad 02 sensors.

How many miles on this car?

Have you done a fuel pressure test?

Have you done a fuel pressure test?

Hi, my brother who is a mechanic took off a hose to see if it was getting fuel and it was. I also forgot to mention I did change the two cam sensors on top on the valve cover but no change.

That's not a fuel pressure test.
P0089

P0089 Fuel Pressure Regulator 1 Performance

Have you figured this one out? I am interested in the problem related to the IAT sensor. I have the same issue, IAT12 drops to -40 as soon as the engine is shut off. Next start and i get a code for sensor 1/2 correlation, but i only have 1 sensor. (non-turbo). Also, I too have replaced the MAF sensor. Problem Persists! Thanks
