The Crankshaft Position Sensor (CKP) is mounted to the transmission bellhousing at the left/rear side of the engine block
New replacement sensors will be equipped with a paper spacer glued to bottom of sensor. If installing (returning) a used sensor to vehicle, a new paper spacer must be installed to bottom of sensor. This spacer will be ground off the first time engine is started. If spacer is not used, sensor will be broken the first time engine is started.
New Sensors: Be sure paper spacer is installed to bottom of sensor. If not, obtain spacer PN05252229.
Used Sensors: Clean bottom of sensor and install spacer PN05252229.
I have found either going from the top and reaching down to get to the sensor, or removing the left tire and going thru the wheel opening the 2 best methods for replacing the sensor. You will want to use a socket and ratchet to remove the bolt, not a wrench. Also, when pulling out the old sensor, use a gentle twisting motion as you are pullling upward on the sensor. Pulling straight up on sensor can cause old sensor to break off in the hole in the bellhousing.
Remove the tire and remove the inner splash shield to reach thru. You are doing blind with this method, but I am used to removing bolts by feel alone.
Like I said, the next easiest way is from the top. You either have to lean over the fender to reach it, or if not tall enough or long enough arms then actually climb up and sit on the inner fender to reach it.
From underneath with a 18" extension and swivel you can reach the bolt, but wont be able to pull the sensor out.
Yes, that is the one for the crank sensor
