Error p0132

Driving to work this am my jeep hesitated while accelerating and shortly after the cel came on. Had the same problem on way home except the idle became "jumpy" a couple of times at stops. Do I need to replace the o2 sensor in front of cat?

So does that mean o2 sensor needs to be replaced?

P0132 O2 Sensor Circuit High Voltage (Bank 1 Sensor 1)
Symptoms

You will likely not notice any drivability problems.
Causes

A code P0132 may mean that one or more of the following has happened:
  • The oxygen sensor heater circuit is shorted out
  • The wiring to the sensor is broken / frayed (less likely)
Possible Solutions

The simplest thing to do is to reset the code and see if it comes back.
If the code comes back, the problem is more than likely the front Bank 1 oxygen sensor. You will likely wind up replacing it but you should also consider these possible solutions:
  • Check for wiring problems (shorted, frayed wires)
  • Check the voltage of the oxygen sensor

Yes, but on the 2000 and above with split exhaust manifolds you have an 02 sensor in each!Upstream and downstream.

Not on my 2000 Sport I don't. Build date of March 2000. 2 piece manifold with the Y pipe and no mini cats. Originally sold in Colorado. I only have two 02 sensors on the whole exhaust system, one before the cat next to the TC and one after...

My 99 TJ started bucking and missing, then the check engine light came on. It seemed to be a fuel issue - too rich maybe? Code was P0132. I took of the gas cap and put back on. Also added fuel injector cleaner. Runs like a top. I dont think it was the fuel injector cleaner as much as it was letting air into the gas tank.
