Jeep Cherokee 1990 Oxygen sensor
Just bought a new O2 sensor for my jeep. It is a 4.0L 1990.
It uses a 3-wire type sensor. 1 for signal and 2 for the heater.
Now, the sensor I got had the wrong plug. Excactly oposite of what i should
bee. So in fact I could plug the new sensor into the old sensor :-)
Well, I needed the sensor i place for my emission test so I transplanted the
old plug onto the new sensor. I know the wires to the heater ar in the right
place because this could be tested measuring about 5 ohm over connector A
and B.
My question then is what are the chances this is working correctly? Anybody
know what jeep the sensor I got fits to? Just worried if the signal is
different than it should be.
The original sensor had a female connector and the new one a male connector
if I remember correctly

BTW the new sensor looked like all metal and the old one had some sort of
ceramic top like a spark plug.

Re: Jeep Cherokee 1990 Oxygen sensor
Checking on the net I found that the sensor I got most likly is for a four
cylinder jeep Cherokee. There also is an image of a universal sensor on the
page that fits both 6 cylinder and 4 cylinder jeep engine. But as I
understand it there are two types of sensors, Titania and Zirconia and they
are not interchangable. Hm....

Re: Jeep Cherokee 1990 Oxygen sensor
Your O2 sensor is under recall. You can get a new one installed for
free if it hasn't already been done. We had our 88's done a few years
ago.
I have heard bad things about the aftermarket sensors with the wrong
plug. One thing is the insulation, you can't interfere with that or
block it I think because the fresh air sample runs down it.
You also heard right that it (some are) is an odd ball sensor with power
going to it.
