I just bought a new crankshaft position sensor and it did not come with a paper spacer. My Haynes manual and what I have found on here says there should be a paper spacer. My question is, are they still using these paper spacers and what if anything can I use as a replacement? I do not really want to drive back to the parts store, its 48 miles away. I have a 96, 4.0 with an autotrans and the one bolt crankshaft position senor. Thanks
Well I just replaced my crankshaft position sensor without the paper spacer and it started up fine.
I cleared the codes and restarted it and the check engine light did not come on.
I am going to take it for a test drive and see how it goes.
I hope this solves my problems.
Curious about this as well, I didn't use a spacer either and haven't had any problems. Maybe the newer models are different but mine had one bolt and didn't have any movement once I put it into the hole. Where's the room for adjustment?
I've ordered a new Mopar CKS as a standby. If it doesn't have a spacer, I guess I'll be trying the cereal box trick. So the spacer is supposed to touch the flywheel, and then get pulled off during normal operation, leaving the end of the sensor at the correct distance from the flywheel?
^ agree. The Mopar CKP didn't come with a spacer, don't remember anything in the FSM about using a spacer when installing, and I've never seen users complaining about the CKP being too close where the teeth of the flex plate ring may chew the end up.
Maybe the hole/new replacement CKP's are designed where if there is the least amount play in it then when you tighten the bolt it spaces itself? I for one would not want to put any type of glue on the end of the CKP and always wonder if it's interfering with the electromagnetic signal of the CKP itself.
FWIW."Be sure paper spacer is attached to the bottom of sensor. If spacer is not present obtain spacer part number 5252229 and attach to bottom of sensor. Push sensor against drive plate and tighten bolt to 60 inch pounds." Excerpt from FSM.
