P1300-CRANKSHAFT POSITION LEARN OUT OF RANGE
For a complete wiring diagram, refer to the Wiring Information.
-
When Monitored:
Under closed throttle decel and A/C off. ECT above 75°C (167°F). Engine start time is greater than 50 seconds.
-
Set Condition:
One of the CKP Sensor target windows has more than 2% variance from the reference. One Trip Fault. Three good trips to turn off the MIL.
Possible Causes |
|---|
| TONE WHEEL/PULSE RING |
| WIRE HARNESS |
| CRANKSHAFT POSITION SENSOR |
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).
Diagnostic Test
1. PERFORM THE CAM CRANK RELEARN PROCEDURE
| NOTE: |
The Cam/Crank Variation Relearn must be performed anytime there has been a repair/replacement made to a powertrain system, for example: flywheel, valvetrain, camshaft and/or crankshaft sensors or components. |
| 1. | Turn the ignition on. |
| 2. | With the scan tool select the "Cam Crank Relearn" procedure under PCM Miscellaneous Menu Option and follow the on screen instructions. |
| NOTE: |
If a negative response is displayed after the Clear Misfire TLC procedure is performed, start the engine and perform the Clear Misfire TLC procedure over until the misfire monitor is cleared. |
Did the PCM complete the Cam Crank Relearn procedure?
Yes
- Go To 2
No
| 1. | Turn the ignition off. |
| 2. | Turn the ignition on, engine not running. |
| 3. | With the scan tool, erase all DTCs. |
| 4. | Start the engine and allow it to idle. |
| 5. | With the scan tool, view DTCs. |
Did the DTC return?
Yes
- Go To 3
No
| 1. | Turn the ignition off. |
| 2. | Visually inspect the CKP wire harness. Look for any chafed, pierced, pinched, or partially broken wires. |
| 3. | Visually inspect the CKP wire harness connectors. Look for broken, bent, pushed out, or corroded terminals. |
| 4. | Verify that there is good pin to terminal contact in the Crank Position Sensor and Powertrain Control Module connectors. |
| 5. | Ensure that the Crankshaft Position Sensor is properly installed and the mounting bolt(s) are torqued to the proper specification. |
Were any of the above conditions present?
Yes
- Repair as necessary
- Perform the POWERTRAIN VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).
No
- Go To 4
4. TONE WHEEL/FLEX PLATE INSPECTION
| 1. | Remove the Crankshaft Position Sensor. (Refer to 14 - Fuel System/Fuel Injection/SENSOR, Crankshaft Position - Removal) . |
| 2. | Inspect the Tone Wheel/Flex Plate for damage, foreign material, or excessive movement. |
Were any problems found?
Yes
- Repair or replace the Tone Wheel/Flex Plate as necessary. (Refer to 09 - Engine/Engine Block/CRANKSHAFT - Removal) .
- Perform the POWERTRAIN VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).
No
- Go To 5
If there are no possible causes remaining, view repair.
Repair
- Replace the Crankshaft Position Sensor. (Refer to 14 - Fuel System/Fuel Injection/SENSOR, Crankshaft Position - Removal) .
- Perform the POWERTRAIN VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).
