Wrangler Throwing Code 0320 but runs fine.

2002 Wrangler Sahara. Engine light came on after having the crankshaft position sensor replaced, code 0320. The jeep runs fine. I don't understand it. Any help appreciated.

Re: Wrangler Throwing Code 0320 but runs fine.

If the CPS has only one bolt to hold it... it's adjustable, and must have the paper spacer on it's tip as it's installed. That maintains an air gap. Without using that spacer the ECM can throw a code.

If the CPS has two bolts to hold it in, they're special bolts to maintain the spacing. Using different bolts screws up the spacing and a code can result.

Re: Wrangler Throwing Code 0320 but runs fine.

Hi LEVE,

It has one bolt. I am not following you about the "paper spacer". Also, could a "mal-adjusted" CPS throw that type of code?

Could I just disconnect the battery cable, pull the CPS and check it for the paper spacer or would I throw it out-of-adjustment?

That's for the help.

EH

Re: Wrangler Throwing Code 0320 but runs fine.

Usually the CPS sensor does not come with the paper spacer. The spacer is just a little dot of thick paper that is pressed onto the sensor. Then the sensor is pushed into it's mating hole and comes up against the flywheel. As the flywheel turns it rips off the paper spacer. So, if you pull it, there may be little to no evidence of it.

If you do pull the sensor, mark it's depth position before you remove it. That way you can get it back close to when you pulled it.

And yes... it can throw the code.

Re: Wrangler Throwing Code 0320 but runs fine.

Could I re-adjust the CPS? or would this be a job for the dealer? I have a factory service manual and I do most of my own maintenance (i.e. time belts, termostates...)?



Thanks,
EH

Re: Wrangler Throwing Code 0320 but runs fine.

As I said, the CPS is adjusted by a paper spacer. If you mark, and remove the CPS and there was no paper spacer on it the you could get a spacer ( I think they're sold in quantity of 5) from the dealer and apply it and reinstall the CPS. That's easily done by you.

If there is a spacer, then you can just return the CPS to the smart marks you made before you inspected it.

Re: Wrangler Throwing Code 0320 but runs fine.

I gotcha. It's sounds like the paper spacer is used for calibration of the cps.

yes, the sapcer is used to calibrate the spacing.
to far away and the air gap o nthe flywheel will cause improper and erratic readings. to close and the sensor can get struck by the flywheel and get damaged.....

Re: Wrangler Throwing Code 0320 but runs fine.

I decided to just reset the pcm. So far; no codes and no problems. I think when the mechanic replaced the cps, he did not disconnect the battery and reset the pcm codes.

The engine light came on because the gas cap was loose (which was a minor evap code, think it was 0442) and therefore the pcm displayed a stored code of 0320.

Thanks for all the help.
