DTC P0315 Crankshaft Position (CKP) System Variation Not Learned
The crankshaft position (CKP) system variation learn feature is used to calculate reference period errors caused by slight tolerance variations in the crankshaft, and the crankshaft position sensors. The calculated error allows the powertrain control module (PCM) to accurately compensate for reference period variations. This enhances the ability of the PCM to detect misfire events over a wider range of engine speed and load. The PCM stores the crankshaft position system variation values after a learn procedure has been performed. If the actual crankshaft position variation is not within the crankshaft position system variation compensating values stored in the PCM, DTC P0300 may set. If the PCM detects the CKP system variation values are not stored in the PCM memory, DTC P0315 sets.
you need a factory scan tool to do the variation relearn .
Install a scan tool.
Monitor the engine control module (ECM) for DTCs with a scan tool. If other DTCs are set, except DTC P0315, refer to Diagnostic Trouble Code (DTC) List - Vehicle for the applicable DTC that set.
With a scan tool, select the CKP system variation learn procedure and perform the following:
3.1. Observe the fuel cut-off for the applicable engine.
3.2. Block the drive wheels.
3.3. Set the parking brake.
3.4. Place the vehicle's transmission in Park or Neutral.
3.5. Turn the air conditioning (A/C) OFF.
3.6. Cycle the ignition from OFF to ON.
3.7. Apply and hold the brake pedal for the duration of the procedure.
3.8. Start and idle the engine.
3.9. Accelerate to wide open throttle (WOT). The engine should not accelerate beyond the calibrated fuel cut-off RPM value noted in step 3.1. Release the throttle immediately if the value is exceeded.

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.
3.10. Release the throttle when fuel cut-off occurs.
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 for the applicable DTC that set.
Turn OFF the ignition for 30 seconds after the learn procedure is completed successfully.

Did you replace the crank sensor ?

Why won't the car start with the new Crank shaft position sensor installed? 2005 Buick Lacrosse cxl 3.8l engine.


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.

What does trouble code P0315 on a 2006 Pontiac Grand Prix mean?


P0315 is a code that indicates and error from the crankshaft position sensor. Typically it is the sensor itself and not an issue with the crankshaft. The sensor itself runs from $30 to $40, but replacement may not be a DIY job unless you're comfortable under a car and removing pulleys from the front of the engine.

2006 chevy aveo check engine light (code # p0315)


I took it in to a different mechanic and am told that the car will not "learn" the cps. It will clear the CEL but as soon as the key is put in the ignition it comes back on He suggested putting in the original crank sensor but that one is cracked so do I need to get an ac/delco or gm sensor instead of what I got from autozone or how do I get it to recognize the sensor we put in?

We did check the fuses and that is not the problem.
