Question OEM or aftermarket Crankshaft Position Sensor?

I'm still struggling with this problem on our 2000GC/4.0. I am thinking of letting a local garage tackle it for me. they want to install an OEM part from the dealer. Said the aftermarket ones available at the parts stores are no good and will not warranty them. Any body else had trouble with aftermarket sensors? (Quite a bit of dollar difference)

Only use a OEM sensor. You will save yourself headaches.

OK, but what is the difference? The ones Advance auto sells have a two year warranty, and labor is included if done at an Auto Repair shop. What is the warranty on the OEM Mopar part, which is what failed in the first place?
(Just wanting answers from those with experience. Thanks for the help. Things are really tight right now and a $300 repair is NOT in the family budget!)

The aftermarket sensors and jeeps just don't get along. You will see many, many threads where aftermarket sensors have failed within the first month or have made problems worse.


I had my transmission done a few months back, and because of periodic problems (once every few months, it would have trouble starting), I went ahead and had the mechanic put in a new Duralast sensor, and the problem started happening every start, he couldn't even keep it running), so he put the OEM one off the used transmission in and it has worked fine ever since. (knock on wood)

OEM sensors have better tolerances and should be used on Jeeps for critical sensors like a CKPS or oxygen sensor, they save alot of hassles over cheaper and less accurate sensors. You can try it of course, but there are alot of threads with strange problems. From personal experience I would say only use a factory Mopar CKPS.

When you say OEM, are you saying just buy from dealer, or is there a certain brand that is OEM for a given sensor?

I currently have an aftermarket one in my Jeep. It's been working just fine for a year now.

I am the OP on this topic. I installed an aftermarket from Advance Auto, and it has been fine ever since! I did get aggravated and "cheated" on the installation. I cut a hole through the driver floorboard to make it easier to access. Gotta be careful, there is either a fuel line or brake line right there that you got to avoid! (I forgot which one it is now)

Mopar is the OEM brand for jeeps, there are a lot of websites sell Mopar parts.

The crankshaft position sensor reads the flywheel and it is mounted on the bellhousing of the transmission rather than the engine.

Does mopar actually manufacture their own parts? I believe someone else makes the parts for them?

Use the OEM, they work and are not that much more expensive.

The question is, what is OEM?
It seems that Delphi made the OEM CPS for MOPAR?
Not that much more expensive is very relative. Im a college student who trains in multiple martial arts. Training and competitions are expensive.
If I can save $20 and still get OEM that makes a difference for my gf and I.
