I would just say take to a service garage
|
Where is the pcm located in a 2007 Mazda 3 2.0? What connections am I looking for at the pcm? I already replaced the sensor.
|
I don't have the money or time for that. :( I need to get the car inspected and in NY you can't unless all check engines are cleared.

POSSIBLE CAUSE
• HO2S heater malfunction • Connector or terminal malfunction • Open circuit in wiring harness between main relay and HO2S terminal C • Short to ground in wiring harness between main relay and HO2S terminal C • Open circuit in wiring harness between HO2S terminal D and PCM terminal 2C • Short to ground in wiring harness between HO2S terminal D and PCM terminal 2C • PCM malfunction Also which sensor did you replace? The 1 closest to the exhaust Manifold or the the 2nd sensor lower down the exhaust? |
I changed the 2nd one.
