Error Code 0132, Oxygen Sensor Shorted to Voltage
 

My 1997 4.0 Cherokee Ltd. sometimes has a very
irregular idle speed and a similar drive problem.
This symptoms are occurring with days or weeks in between,
but sometimes appear a few times a day.
After a few minutes, the problems go away, and the car has
no problems at all. The engine starts easy. No other problems.
A computer check at the dealership has produced the following
error message:

Code 0132, Oxygen Sensor Shorted to Voltage

Do I have to replace the sensor, or is the problem somewhere
along the electric transmission between the sensor and the motor
management unit?
I am living in Asia, and parts have to be specially ordered and are
very expensive. I hate to have the sensor replaced, just to find,
that the problem is somewhere else.

Thanks for any input.

Re: Error Code 0132, Oxygen Sensor Shorted to Voltage
 

My 94YJ did the same thing. High O2 sensor voltage (Code21 OBDI). This
happened after a drive in through a deep creek. It shorted out the O2
sensor. If parts are that expensive there, I would start checking voltages
and looking for a short in the O2 sensor wiring.

I'm not sure if the 97 Cherokee models have an upstream and a down stream O2
sensors. If they do, make sure you check both.
