Crank sesnor, easiest way?

**bve32k** · 02-08-2010, 08:08 AM

What is the easiest way to get to the crank sensor? My car right now is having intermittent spark and the only thing I can think of is the crank sensor.

So what is the easiest way to get at this damn sensor? I replaced it before, but the that was when I had the heads off the car. It was much easier.

Edit: Anyone know the normal resistance on the sensor?

Not sure on resistance, but take off the passenger side tire and go through the wheel well if you have an auto. Go from under the car if you have a 5 speed.

as far as I can figure if you have an automatic, alternator removal is necessary to get at it, it was the only way I could do my old euro 3.4s crank sensor.

I have never had to remove alt to replace sensor.

I don't think I would be able to get to the sensor without removing the alt. There is just no room to get at anything. I was going to try from bottom, but I have a feeling I will not be able to get to it from there. It was an option to from top, but that is sounding pretty risky too since the exhuast manifold is in the way.

Anyone have any other 2 cents. Anything is appreciated.

You cannot go by the resistance reading for that sensor. It will show good readings when cold/warm and still not permit signal. When its hot it may or may not show bad readings and still permit a good or bad signal. That is why I didn't tell you or ask you to check for any readings from that sensor. That is also why I told you to check for those small hairline cracks.

Just drive the car for now, it's not like you will be doing any long hauls anytime soon. AAA FTW use it!

If you removed your exhaust system you might be able to get to it from under the car, otherwise the down pipe is a key blockage there.

I ended up getting it out from the passenger side wheel well and it was a pain in the but. Had to take the alt out and then I could get to the sensor. I tried from underneath and I tried from up top with the UIM off. I could touch it, but that was about it. Couldn't do anything else with it.

I've gotten the crank sensor out from under the car using a ratcheting wrench with another wrench black taped to it for extra length. Did it in 10 minutes. You just need a good trouble light and have a set of very long alligator scissors that lock at the handle to put it back in and put the harness back on.

There is no way! I don't know how you guys are doing it with everything on. I almost couldn't get it off by having the alt off. There is just no room. I could get the ratchet on, but that was about it. Could not turn it or do anything with it.

Maybe the 94 - 96 motors are different than the 91's. I don't know.
