Is this a cherokee sport with 4.0L engine?


does the check engine light ever come on right before the engine shuts off?

its a wrangler 4.ol


Expert:  Eric replied 8 years ago.



This is normally due to an intermittent fault in the crankshaft (ckp) sensor. This sensor sends a signal to the computer to sychronize the firing of the injectors and the spark plugs. when the signal is lost the engine quits. When the engine quits it automatically resets the ckp sensor, thus allowing it to start right back up.


The sensor is located on left side at top of the bellhousing where it meets the engine.

4.0L Engine

The Crankshaft Position (CKP) sensor is mounted to the transmission bellhousing at the left/rear side of the engine block. The sensor is adjustable and is attached with one bolt. A wire shield/router is attached to the sensor.

  1. Disconnect sensor pigtail harness (3way connector) from main engine wiring harness.
  2. Remove sensor mounting bolt.
  3. Remove wire shield and sensor.


To install:

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.

  1. Install sensor into transmission bellhousing hole.
  2. Position sensor wire shield to sensor.
  3. Push sensor against flywheel/drive plate. With sensor pushed against flywheel/drive plate, tighten mounting bolt to 7 Nm (60 inch lbs.) torque.
  4. Route sensor wiring harness into wire shield.
  5. Connect sensor pigtail harness electrical connector to main wiring harness.
