After hitting a fairly substantial bump in the road my 2005 Crossfire convertible lost all power. I coasted to the side of the road and was able to immediately restart the car but continued to have intermittent power failures.

My mechanic diagnosed the problem as a bad crankshaft position sensor and replaced the sensor but the power failure problems continued, usually when accelerating quickly or going up a hill, but sometimes the car suddenly loses power while travelling at slow or at moderate constant speeds.

I returned the car to my mechanic who found that he could manipulate the ability of the car to start, or to lose power after being started, by jiggling the wire that leads to the crankshaft position sensor. There seems to be a short in the wiring harness and i'm not sure if Chrysler still makes an engine wiring harness replacement part.

Has anyone encountered this problem or know of a potential solution?

 

1) I'm having a hard time blaming the "wiring harness". If anything, I'd question the contact made between the male terminals in the boot plugged onto the CPS and the female pins of the CPS itself.

Or..............
2) Sounds to me like a generic crank sensor was installed. Others have reported that non-Bosch, locally obtained CPSs from Autozone, etc. will act like this.

Order one of these:

3) Chrysler does not make parts for these cars, they never did. What's worse, is they stock (apparently) no parts to speak of, either.

 

#2 What Pizzaguy said. Sounds like an intermittent (not short) in the CPS connector. Let us know if a BOSCH CPS replacement fixes this.

Agree with feedback received. When looking for CPS, Bosch and/or Hella are good choices.
