I have a 2020 Equinox 1.5 liter. After replacing the hood and bumper cover I am getting codes p0299 and p2227 and the engine has reduced power. The accident left moderate damage to the core support and hood. Everything was replaced. I’m wondering if these codes might be the turbo or catalytic converter? I thought maybe one or the other might have been damaged internally. Anyone have any ideas??

Best I can tell the P0229 is an underboost code and the P2227 is something to do with barometric pressure circuit A.

Was anything damaged on the charge air cooler? This is a pretty fragile part, right in the path of any front end collision. I'd check the charge air cooler for signs of leakage. You'll usually see oily vapor leakage from the bad areas. Also check the big hose clamps going into the charge air cooler, out of it and at the throttle body.

If all that is good, I'd check that baro pressure sensor/circuit, the MAF sensor and circuitry, etc.

If all that is good, It could be a turbo problem.

I’ve checked and rechecked all the connections at the ends of the intercooler and the air clean housing. The damage was above the front crash bar higher up so it didn’t damage the lower intercooler. Thanks for the info..

If you're sure the charge air cooler and all it's plumbing are intact, I'd check the turbo waste gate actuator and solenoid. I believe the actuator is vacuum powered and the vac is turned on/off by the solenoid. Other than that, you'd need to scan for live data to see how the baro pressure and boost pressure are reading and behaving.

After all, that P2227 code is a circuit code, so it could be a broken or corroded wire or bad connection to the baro press sensor.
