If you have changed out the parts and still get the codes you probably need to have the ECM reset. The dealer can do that for you or a repair shop that has the scan tool.

SOURCE: how do I change the oxygen sensor in my 1997 Jeep

Unplug sensor cable from connector. Use 7/8" Oxygen Sensor socket, available at most auto supply and tool stores for around $10, to remove the sensor (It's a deep well with a slot cut up the side to clear the four wires that come out of the end of the sensor) . Insert new sensor using the same socket. The threads should have anti-seize compound already applied to them by the manufacturer. That is adequate. Plug the sensor connector into it's mate. That one is done. There are two Oxygen sensors on my '97 Wrangler. One is in the downpipe just after the connection to the exhaust manifold and the other is just after the catalytic converter. Easy to do!

Looking for wiring diagram of plug to map sensor on 03 jeep wrangler


Step 1:

The orange wire is the power wire. You should have 5 volts on this wire with the key on.


Step 2:

The dark green w/red wire is the signal return. Voltage will vary on this wire from less than a volt to just under 5 volts depending on if the engine is off, running, or what RPMS the engine is running.

Step 3:

The black w/light blue is the sensor ground.

I have a 97 jeep wrangler 2.5 with auto trans. The last year I have replaced the up stream 02 sensor 7 times. The jeep will run fine for a month or so then the check engine light will come on. Its always...


My used 97 jeep wrangler fuel / economy problems: My vacuum canister was completely full with crud (replace). also my coolant temp sensor was bad (twice replaced), effects fuel mixture. and O2 sensors were bad (effect fuel mixture) due to being fouled by spraying too much oil on spector air filter (now wipe off excess and let dry in sun), also carb cleaner appeared to foul O2 sensors (stopped using). Also sensor input/output signals were constantly being interrupted by battery sliding into computer harness, which I cured by placing a 1" spacer on rear battery clamp to push battery away from computer. After curing these problems my fuel economy went from 55-60 miles per 1/4 tank to 75-80+ miles per 1/4 tank.
