Crankshaft position sensor stuck.

What's up everybody.
It has been a while since I posted anything on the forum. Been busy with school, work and renovating the new house (doing all the work myself), that I barely have time for anything else.

Here is my problem.
My jeep runs like a champ, but from time to time, I have problems when starting it. Sometimes when I start the jeep, the rpms start jumping and it stalls, usually on the second try it starts fine (this only happens once in a while). I replaced the camshaft position sensor a while back, but the problem still occurs. I know that it might also be the crankshaft position sensor.

I bought an OEM crankshaft sensor and tried changing it today, since the weather is so nice. I get under the jeep, ready to replace the sensor and I run into a problem. I disconnect the sensor, remove the bolt, but the sensor is stuck and doesn't move at all. I tried pulling it out and rotation it clockwise/counterclockwise by hand and with tools without any luck. I was afraid to use too much force and breaking the sensor, then ending up towing it to the mechanic.

Did anybody else experience the same problem and if you did, how did you remove it?

Thanks in advance.

Re: Crankshaft position sensor stuck.

Did you already spray some WD40 or other lubricant on it? The O-ring is dry and probably all kinds of dirt are in the hole before the O-ring. I know at least from one other member who had the same problem and i didnīt hear from him if he finally could get it out.

Re: Crankshaft position sensor stuck.

If you can find PBblaster, try that. Seems to work a bit better than wd-40.

Re: Crankshaft position sensor stuck.

I did not use any of the lubricants.
Ill try to spay some WD40 next time I am under the jeep.
Hopefully that will work, because I could not even twist it.

Re: Crankshaft position sensor stuck.

I changed mine out just a few months ago. Was a huge PIA! I have the 3.7 and went from the under side and through wheel well. Would not turn either. I took very long screwdriver and very lightly and carefully worked on it to get it moving. I sprayed pb blaster on it and let it set. Pulled on it with needle nose and I totally destroyed it, but I finally got it out. It was in fact stuck on the o- ring.

I guess I'll give pb blaster a try. I'm just afraid of breaking it and still not being able to pull it out.

Re: Crankshaft position sensor stuck.

If its that stuck,it's likely that it will break. All is not lost. You then can pull on the copper wires sticking out or drill a hole,insert a screw and use something as a pry bar slipping under screw head and prying out. Serious pain in the ass. If you aren't comfortable you can always stop before the plug is off and take it somewhere. I went through all of this,so you aren't alone.

Did you do all that from under the jeep?
It was a pain in the ass, trying to remove it from under the jeep, all the rust and dirt falling into my eyes. I think I'll put on some glasses next time.
If I use PB blaster, should I let it soak in for a few hours, before trying to remove it?

Re: Crankshaft position sensor stuck.

Jacked it up, took off skid plate and wheel and went crazy.pic is off internet, but exactly like what I did. I got to the point where it seemed like my only option. To go ahead and break it and put a screw in it.. Sorry I didn't get back sooner, but I was putting in a new driveshaft and o2 sensors( the passenger side was horrible) connector tucked behind the tranny dip stick and the firewall. Hands looks horrible. Price we pay to drive our jeeps I suppose. I love my Wk one day and hate it the next... Just keep at it and you'll get that pig outta there. PB blaster is my pal. I always have a full can. I soak something for awhile before I mess with it. Usually does the trick.

Re: Crankshaft position sensor stuck.

I had the same issue with my crankshaft sensor, the pb blaster worked like a charm! Thanks guys for the heads up.
