I replaced the crank shaft sensor on the vehicle mentioned above and now the car won't start. I took the new sensor back and got a new one but still the same problem no spark! I put the old sensor back into the car and it started right up but will stall after a few miles. Why won't the car start after the new sensor is installed? Does this mean i need to replace the harmonic balancer?
After replacing crank sensor Perform the crankshaft position system variation learn procedure. Refer to Crankshaft Position System Variation Learn !
No you don't need to replace the balancer !
Install a scan tool.
Monitor the powertrain control module (PCM) for DTCs with a scan tool. If other DTCs are set, except DTC P0315, refer to Diagnostic Trouble Code (DTC) List - Vehicle in Vehicle DTC Information for the applicable DTC.
Select the crankshaft position variation learn procedure with a scan tool.
The scan tool instructs you to perform the following:
4.1. Accelerate to wide open throttle (WOT).
4.2. Release the throttle when fuel cut-off occurs.
4.3. Observe the fuel cut-off specifications for the applicable engine.
4.4. The engine should not accelerate beyond the calibrated RPM value.
4.5. Release the throttle immediately if the value is exceeded.
4.6. Block the drive wheels.
4.7. Set the parking brake.
4.8. DO NOT apply the brake pedal.
4.9. Cycle the ignition from OFF to ON.
4.10. Apply and hold the brake pedal.
4.11. Start and idle the engine.
4.12. Turn the A/C OFF.
4.13. The vehicle must remain in Park or Neutral.
4.14. 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 the applicable DTC.
• Camshaft position (CMP) signal activity--If there is a CMP signal condition, refer to the applicable DTC.
• 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.
Enable the crankshaft position system variation learn procedure with the scan tool and perform the following:
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.
5.1. Accelerate to WOT.
5.2. Release when fuel cut-off occurs.
5.3. Test in progress.
The scan tool displays Learn Status: Learned this ignition. If the scan tool indicates that DTC P0315 ran and passed, the CKP variation learn procedure is complete. If the scan tool indicates DTC P0315 failed or did not run, refer to DTC P0315. If any other DTCs set, refer to Diagnostic Trouble Code (DTC) List - Vehicle in Vehicle DTC Information for the applicable DTC.
Turn OFF the ignition for 30 seconds after the learn procedure is completed successfully.
The CKP system variation learn procedure is also required when the following service procedures have been performed, regardless of whether DTC P0315 is set.
• Engine replacement
Testimonial: "Thank you very much!!"
You have to do a crank sensor relearn
I concur on this one. You need a scan tool..although I do not concur on your reasoning for going to the crank shaft sensor for a stalling problem OP.. did you check for anymore leaks in the boat before landing on that island??? Later Gator.
