Question about 2001 Chevrolet Silverado 2500HD
Crankshaft Position Sensor: Service and Repair
Crankshaft Position (CKP) Sensor Replacement
IMPORTANT: Care must be taken when removing the crankshaft position (CKP) sensor. Use penetrating oil and allow to soak around the CKP
sensor before removing the sensor. Twist the sensor to break the O-ring seals loose. When removing the sensor, pull the sensor straight out of the
engine block at the same angle the sensor was installed. Failure to be careful may result in sensor damage.
1. Raise the vehicle. Refer to Lifting and Jacking the Vehicle.
2. Disconnect the crankshaft position (CKP) sensor harness connector at the CKP sensor.
3. Remove the fuel line bracket and retaining bolt.
4. Use penetrating oil and allow to soak around the CKP sensor before removing the sensor.
5. Remove the CKP sensor retaining bolt.
6. Prior to removal of the CKP sensor, rotate the sensor back and forth.
7. Remove the CKP sensor at the same angle at which the CKP sensor was installed.
IMPORTANT: Inspect the CKP sensor O-ring for wear or damage. If a problem is found, replace the O-ring. Lubricate the new O-ring with engine
oil before installing.
1. Install the CKP sensor at the same angle at which the CKP sensor was removed.
NOTE: Refer to Fastener Notice in Service Precautions.
2. Install the CKP sensor retaining bolt.
Tighten the bolt to 12 N.m (106 lb in).
3. Connect the CKP sensor harness connector.
4. Install the fuel line bracket and retaining bolt.
5. Lower the vehicle.
6. Perform the CKP System Variation Learn Procedure. See: Testing and Inspection/Programming and Relearning
Crankshaft Position Sensor: Service and Repair
CKP System Variation Learn Procedure
IMPORTANT: For additional diagnostic information, refer to DTC P1336.
1. Install a scan tool.
2. With a scan tool, monitor the powertrain control module for DTCs. If other DTCs are set, except DTC P1336, refer to Diagnostic Trouble Code
(DTC) List for the applicable DTC that set.
3. Close the vehicle's hood.
4. With a scan tool, select the crankshaft position variation learn procedure.
5. Observe the fuel cut-off for the engine that you are performing the learn procedure on.
6. The scan tool instructs you to perform the following:
^ Apply the vehicles parking brake.
^ Block the drive wheels.
^ Cycle the ignition from OFF to ON.
^ Apply and hold the brake pedal.
^ Start and idle the engine.
^ Turn OFF the A/C.
^ Place the vehicle's transmission in Park (A/T) or Neutral (M/T).
^ The scan tool monitors certain component signals to determine if all the conditions are met to continue with the procedure. The scan tool only
displays the condition that inhibits the procedure. The scan tool monitors the following components:
- Crankshaft position (CKP) sensors activity - If there is a CKP sensor condition, refer to DTC P0335 or DTC P0336.
- Camshaft position (CMP) sensor activity- If there is a CMP sensor condition, refer to DTC P0341, DTC P0342 or DTC P0343.
- Engine coolant temperature (ECT) - If the engine coolant temperature is not warm enough, idle the engine until the engine coolant
temperature reaches the correct temperature.
7. With the scan tool, enable the crankshaft position system variation learn procedure.
IMPORTANT: While the learn procedure is in progress, release the throttle immediately when the engine starts to decelerate. The engine control is
returned to the operator and the engine responds to throttle position after the learn procedure is complete.
8. Slowly increase the engine speed to the RPM that you observed.
9. Immediately release the throttle when fuel cut-off is reached.
10. The scan tool displays Learn Status: Learned this ignition. If the scan tool does NOT display this message and no additional DTCs set, refer to
Symptoms - Engine Mechanical. If a DTC set, refer to Diagnostic Trouble Code (DTC) List for the applicable DTC that set.
11. Turn OFF the ignition for 30 seconds after the learn procedure is completed successfully.
