Re: 02 sensor
On my 96, all four sensors are the same. It can work to your advantage. The front two are actually heated by the ECM. The cat two are not. I had a front sensor go bad. It would not heat up properly. I swapped it with the rear most sensor. Worked like a charm and didn't have replace a new sensor.
ODBII systems can give codes for all four sensors. Looking for a replacement is easier it individual sensors are listed. In some cases, the sensors could actually be different. |
