Error codes + traction light after body shop
 

So I had my car in the body shop getting fixed after a guy backed into me. A family member works for the shop so they drove it home for me. While driving home, she noticed my traction light was staying on, and the CEL was on (comes on occasionally from my header). I scanned it, and I got the following codes:

P2096-(normal code I get from the header)
P0191-Fuel rail sensor pressure
P219A-Air/fuel Ratio imbalance

Since the repair was done on my front bumper, I'm thinking maybe they didn't hook my intake up properly. If I'm leaned out from that, there's the imbalance. And the fuel rail pressure sensor could be from it trying to overcompensate for the extra air.

None of that explains the traction light though...

Anyway that's my best guess. Anyone else? Any help is appreciated.

P.S. Took it for a test drive, seemed ok. Normal conditions for when the CEL is on. Cleared the codes and it ran great, no codes after about 5 miles.

P2096-(normal code I get from the header)
You should not get that code after installing header unless you have a leak near o2 sensor / intake leak or damaged 02 sensor.

Code you get for catless header is P0402 (cat efficiency)

Those other two code you had point to intake/exhaust leak or problems with post cat 02 sensor.

If the second 02 sensor is crook or disconnected it will generally cause cruise control to be inoperative but im not sure if it triggers traction light.

Check the plugs on the front/rear 02 sensors are seated correctly they are near alternator at front of motor. They are grey and black coded and the plug and socket colors should match.

Same happen with me after the body shop the light is on and only this light did you ever get it fixed and what was it?

There is your problem right there...

If the engine management system is not "happy", then it can disable the TCS.

Either that or the accident affected your wheel speed sensors.

Well I cleared the codes that night and they never popped up again. It wasn't from the accident because the accident was super minor, and I waited a week to put it in the body shop. I still get the p2096 code but keep it cleared. It's possible that the MAF was disconnected when they fiddled with the intake to remove the bumper, and it had to recalibrate.

Hilarious lol.

LOL wasn't sure if anybody was going to catch that

So how do you recalibrate??

Mines is still doing the same and the code won't go away also cruise control won't turn on

Same here I get the fuel ratio unbalance and can't seem to find the issue and the front sensor is a bitch to even get to I'm guessing I'm just going to deal with after I get headers and all

You don't, the computer on our cars "learns" on it's own after ~50 miles. Back in the earlier days of ECU's, you had to reset the computer manually.

So your saying it will fix on its own?? Becuase this fucking is driving me nuts especially when I'm in the 4000rpm range the car hesitates a tad

do you have standard intake, aftermarket intakes upset maf scaling and ecu cannot compensate accuratly

can you log your tune ?

log fuel trims STFT LTFT
AFR
Commanded AFR
load
rpm
knock correction
FLKC
IAM


hesitation sounds like afr is incorrect or high fuel trims or you getting knock causing ECU to pull timing causing hesitation.
