Check Engine Light - O2 Sensor   Message List

Re: [Colorado XJ] Check Engine Light - O2 Sensor

There's 2 o2 sensors on the XJ's. One is located just after the manifold on the exhaust where it bends and the other is just before the cat. About that time to replace it seems, they need to be replaced usually every 60,000.  I would go to NAPA to get them, better warranty in my opinion.

Hey all,
While cruising along 225 on friday the engine light came on. I read the codes and they came out to 12-21-55. My handy-dandy notebook suggests that this is because the O2 sensor is not sending the right voltage. At 85k I assume it it probably time for a new sensor but there is one catch... I have no idea where it is on the system. Does anyone have any advice here? Maybe a schematic or description of where to find the sensor?

Make sure you get the direct replacements & not the universal's, they can have issues where you splice the wires. ?Toby? ... From: David Sandoval...
