Crank position sensor

Should I have removed the paper off the new sensor?, the directions said not to, but after replacing the engine still has no spark, but the old sensor that I had tested indicated faulty and I am wondering if I need to remove the new one and remove the paper.

Thanks all,

Directions are as follows:

Do not remove paper on sensor tip. The paper spacer is about .030 inch thick pasted on the of the sensor probe. should not remove prior to installation. it provides the required air gap between the sensor and engine moving parts. After installation and the engine is started, it gets sheared off.

My question is how do I know it is touching enough to shear off the paper? and if it does'nt then it won't start...right?

You did not post your Cherokee information. The correct answers to even the most simple questions will vary significantly based on your model year, engine size, transmission, and transfer case. ALWAYS include this info in your tech questions.

There are three type of Crankshaft position Sensor Mounting styles. You need to be sure the replacement CPS is the correct style for your year of XJ.

A) 2 Bolts
B) 2 Nuts
C) 1 Bolt

The paper spacer is for the 1 bolt style. The 1 bolt style is for older XJ's. Press the CPS firmly into the hole to make contact. If you have an older XJ that uses the one bolt style CPS, follow the instructions.
