P0335 turned into P0339

[Kittykat12]

Hi all, I have a 05 Liberty 2.4l 6 speed, about 173,000 miles, that was throwing a p0335 code. I replaced the crank sensor(part no. 907-763) and the IAC(code popped up too and is gone now). But when I reset the code by pulling the battery, and drove 3 city blocks, it popped the code P0339. And it now has a hard time starting, and when it does it will not go over 2400 rpm, and runs really horribly... any thoughts?? Please and Thank you.

first thought is:
Did you use an OEM Mopar part? These things are very picky on engine electrical components.

I did not... not going to be able to get that until Friday. I got the Dorman from Autozone.

That is probably the culprit. If you read thru here, you will find the OEM sensors are almost a must to get the thing working right.

Yes, you must use original Mopar sensors. The aftermarket ones can cause problems or last one year or less....
