Two problems related to o2 sensor have been reported for the 1996 Jeep Grand Cherokee. The most recently reported issues are listed below.
My vehicle stalls when it is hot outside. I have had the coil replaced then I had the catalytic converter replaced and O2 sensor and it still stalled on start up. I took it to the dealership and it stalled and they told me it was my fuel pump. I spent 965 on a fuel pump I didn't need because it is still stalling and they have no clue why. I seen this problem on mean forums. I think the dealer should be aware of this problem and should know how to fix them not make someone spend a thousand dollars on a might.
While driving at 30 mph, the vehicle stalled. When this occurred, the steering wheel locked up and the brakes failed to function. The dealership indicated that this was caused by an electrical system sensor failure. The consumer stated the engine light illuminated and apparently the problem was the oxygen sensor, also the monitor light on the dashboard blinked which indicated there was a rear lamp failure even though there was no failure.
