I have reset the codes numerous times, actually my car has shut off once or twice... like it would with the egr leak. But I have a aluminum plate on it that is copper RTV'd. I may remove that again and reseal.
Im not getting a code for my o2..just these
DTC Code : P0101
Description : Mass Air Flow (MAF) Sensor Performance
DTC Code : P0121
Description : TP Sensor Circuit Insufficient Activity
I just bought a new o2 sensor. And the extension harness was from zzp. I am going to check those wires when I get off work.
I also bought some electrical parts cleaner, but I have never used it before.
