Crankshaft Position Sensor Circuit

Hello all. I was just cruising in my 05 Grand 5.7 and was leaving the grocery store, I gave er some juice just to be cool and enjoy the HEMI but when it was supposed to shift I felt and heard a loud bang and then the check engine light came on and the traction control shut off. I drove home which was like a few k's away and took it easy on the throttle. When home I shut the jeep down and turned it back on, the traction control seemed to be back on but the engine light was still there. I did the old three turn of the key and came up with the P0335 which I found out via WKJeeps.com (awesome) is the Crankshaft Postion Sensor Circuit. My question is does this mean it's only a sensor or is there more issue going on here. I have been experiencing the jeep slightly stuttering/bucking while driving at approximately 50-60 mph, but found many people stating this is a fairly normal trait of the 5.7 grands. I did also experience a couple loud hard shift a few weeks back but thought nothing of it. I had the tranny/t-case fluids changed and used only mopar fluids, well except for one quart of quaker state in the tranny. Friggin guy through it in because I needed a tade more, and I didn't get a chance to stop him. Whats should I be doing next?

Thanks muchly
n8jay

Re: Crankshaft Position Sensor Circuit

I had the same symptoms about a year ago. My sensor was on the way out its real cheap and easy to replace! It cost me around $20

If I remember right its located on the rear passenger side of the block above the oil pan. So you will need to get underneath the vehicle. One bolt holds it in. Unplug your battery first. Then unplug and unbolt then pull the old sensor out. Clean out the hole it sits in. Lube up new O-ring on new sensor with some oil then insert it in...you may need to twist it a bit("That's what she said"... couldn't resist). Reinstall bolt and then plug it back in. Connect battery/clear DTC's.

Now for the oil if it was ATF+4 you will be fine...

Re: Crankshaft Position Sensor Circuit

The crank position sensor and the cam position sensor are two of the few things that can leave you stranded in your 5.7 WK, if one or the other fails. For this reason I carry one of each in both my Hemi vehicles. Here's the P/N's right off the packages:

Crank Position Sensor: 1-56028815AA (Made in Mexico)
Cam Position Sensor: 1-56041584AF (Made in USA)
