2002 PCM in a 2003?

[aidanm]

Hi all,
I’m having a p0306 code in my 2002 Sahara and my father’s is a 2003 rubicon and was wondering if the computers could be swapped to see if the misfire follows to his motor? I’m sure @Wranglerfix would know. Thanks!

Yup

the oil pressure sensor went from a 3 wire in 02 to a single wire in 03. It should run but the 02 pcm on an 03 jeep will show no oil pressure.

I don’t remember there being any other differences.

This is assuming both are manual trans.

Now if either of you have SKIM, grey keys, do not swap the pcms. If you both have black keys good to go.
