New tires: Check engine/traction control lights on

[BPo001]

I got new tires put on yesterday (BFG A/T 265/70/17). Drove to work and home had no problems. Started my car up this morning to go to work and my check engine and the 3 traction control lights are on. Any idea what could have caused this? Car seemed to drive ok to work this morning, but don't want to drive it if it's going to mess anything up. TIA

Wow odd , could be bad timing or maybe abs sensor wire got pinched ? Easiest would be obd 2 & scan for codes ?

X2 Go see what codes it threw.

went and got the codes pulled for the check engine light. Code is P0456 which they said could just be a faulty gas cap. Still doesn't explain the traction control lights and stuff though does it?

All of those lights come on at the same time for most if not all codes.

I got the faulty gas cap code not too long ago, tighten the cap and wipe the code and see if it goes away. If it doesn't, buy a new gas cap and it should go away. mine did.

I bought a new gas cap and cleared the codes, but they just came back on today. Any idea what it could be? I feel like it has to do something with the tires.

Check abs codes not just engine PCM

Has NOTHING to do with the tires.

If there's any kind of engine code...the ECU automatically disables traction control and ABS.

The P0456 code COULD mean a bad gas cap. Could also mean a bad charcoal canister. Something is wrong with the EVAP system. Most of the time it's a gas cap. Did you buy a OEM gas cap? I had the same problem about 3 years ago. I went to my local trusted auto parts store and bought a gas cap. Then I cleared the code..and one day later the code is on. So I went to the dealer and bought an OEM cap. Cleared the code and it stayed clear.

you also may need to reset your zero points for the yaw and decent control system some code scanners will erase the zero points while reading codes.

Another gas cap victim here. Bought it used and brought it back to the dealer 3 times to have the codes cleared, they couldn't figure out what was wrong. I thought the gas cap felt funny when I would tighten it. Replaced the cap, (OE) cleared the codes, no problems.

I bought the gas cap from a Toyota dealership. What is the charcoal canister?

OBD-II Trouble Code: P0456 Evaporative Emissions System - Small leak detected

The service history on mine shows that the code flashed for "evap" something or another, and the dealership tightened the gas cap, cleared the codes, and no more problems since.
