2012 jeep wrangler camshaft position sensor bank 1 sensor 2

Replacement and Installation

Caution: The magnetic timing wheels must not come in contact with magnets or any other strong magnetic field. This will destroy the timing wheels ability to correctly relay camshaft position to the camshaft position sensor.

The CMP sensor identifies the position of the camshaft to the ignition control module (ICM), engine control module (ECM) or powertrain control module (PCM). The ECM uses this data to determine the timing of the ignition, as well as the timing of the fuel injection required by the engine. When the sensor fails to do its job, the engine can’t function properly.

When not replaced, the vehicle could experience hard starting (or failure to start), long crank time, misfire, decreased power, spark plug fouling, catalytic converter failure, poor fuel economy or intermittent shutdown … all fine reasons to replace the camshaft position sensor.

Often, these symptoms will be accompanied by the dreaded “check engine” light. If so, an automotive computer scanner should be able to confirm whether or not the sensor is the problem. Many automotive supply stores will scan your vehicle’s onboard diagnostic system free of charge.

If you determine the camshaft position sensor is the problem, the good news is that replacement is usually very simple, if you can easily gain access to the sensor. The CMP sensor is mounted in several different places, depending on the model. The sensors are specific to vehicle and range in price from $10 to more than $80.
