S14 SR20det o2 wiring question
Long story short, i had the wire in pin 115 (o2 sensor heater) come rip out of my ecu connector somehow. I tried to re-pin it and i am not sure it is making a good connection. The 02 sensor is not getting hot until the car has been running awhile, which is throwing off my AFR's at idle until it is warmed up.
Is this o2 wire just a ground? If so can i ground it to the chassis? i am assuming it is causing the heater circuit to not work correctly.  |
