Crankshaft Position Sensor, Which One?

I'm getting a code 11 and it could be my CPS. My questions is which one should I get? My yj is a 91. Everything is 91 except for a new engine which is a 94 with a 94 distributor and coil (if that matters). So when I look it up the part numbers they are broken down with a 91 and 82 has one and the 93 thru 95 has a different one.

Any idea?

Craig

Just checked the sensor and it is at 69 ohms. So pretty sure it's bad. Need to figure out which one to get.

Which year ECM controls the emissions system on your Jeep? '91? Then that year sensor would be the logical choice.

Do you know what was good about the good old days? I wasn't good, And I wasn't old!

Senators and Congressman should wear uniforms like NASCAR drivers so we could identify their corporate sponsors....

Thanks, It is a 91. I was leaning that way. I checked and the distributor sensor is the same for those years.

And I just got a good look at both and it is the mounting strap that is difference between the two.

94 PCMs are a little different IIRC. I believe the 94 dizzy will have a different Camshaft sensor signal.

Between 91-94 several different crank sensor part number show up.

Picked up a sensor at NAPA for a 91 YJ and it runs great again. I think it was going down hill for a while because it actually feels a little smoother.

thanks for all the input!!

The PCM and the signal is the same. The sensor connector changed. You can cross over the 2 with no difference in the way it will operate. The older one is round while the newer one is flat.
