O2 sensors on 1996 Explorer 4.0

The check engine light is lit on 1996 Eddie Bauer. It has the 4.0 V6. The ODC said it is the #1 sensor. Does anyone know the location of this sensor?

Depends on what "bank" for your #1 sensor... bank 1 sensor 1 is forward of the cat on the passenger side, bank 2 sensor 1 is forward of the cat on the driver side.

02 sensor

Thanks. I believe it said bank 1. Once the sensor is changed, does anything have to be done to reset the check engine light or will it go out by itself?

That will depend on why the code was set. Diagnostic codes don't ofter specify which part is bad, but rather what sensor is reporting an issue. Depending on the particular diagnostic code (there are SEVERAL relating to oxygen sensors), the issue could be with the wiring, due to a misfire/vacuum leak, improper fuel, etc. If you just replace the sensor and the problem is a broken wire to the sensor, no, the check engine light will not go out.

Do you happen to have the exact code, probably in the form of P0123?

O2 sensor

No, I don't believe the ODC gave that. Thanks for the help.

You will need to get a o2 sensor socket... it has a side cutout so you do not break the wire on the new sensor.

Be aware that without the proper diagnostics, changing parts may not fix the problem.

It will however lighten your wallet.. Philip
