Well, The check engine light comes on to day.. Took it to Autozone for a diag test.. Say code is po155..
Take it to Autozone for a diag test.. Says it may be the gas cap. Try that first he says.. If not, get a smoke test on the fuel system as it is losing compression fast on start up. I look up the code and it says O2 sensor. Any suggestions??
Yes, P0155 is either a failed O2 sensor or the wiring harness or connector to the O2 sensor is faulty....http://www.obd-codes.com/p0155
