Crankshaft Position Senor Question...

[SeriousSide97]

guys Im doing a few fall tune up things on the hoe. Now I want to replace the crankshaft position sensor but If I do, will I have to relearn the cps when Im done. Im not throwing a code or anything but I believe the one Im using is orginial and might have a worn gasket on it. any help would be well appreciated.

If you replace the crank sensor you have to have to do the relearn procedure weather or not you get a code about it.

really? whys that ? how much do you think a dealer will charge me to relearn it?

There are always small variances during manufacturing that at rpms can be a tad bit different then the last one. The computer needs to perform the test so it can distinguish was it is seeing with the new sensor. If it is not done and you misfire is may give false readings on what cylinder is misfiring among other things. It is a 10 minute procedure really and you should not get charge more the 30 min of labor. Might even get it done for free.

As long as you reinstall it you are fine.
