Today I was at the redlight and just happened to notice that my service engine light had came on. I pulled the codes a minute ago and got these:
PCM 0151 heated O2 sensor circuit low voltage bank 2 sensor 1
PCM 0174 Fuel Trim system lean bank 2
PCM 1139 Heated O2 sensor insuff. switching bank 1 sensor 2
This makes sense to a point but performance wise I have no idea what they mean and what caused the codes to appear. Is this major or something that can be corrected. I'll wait for a response before I clear them.
