Hello,

Here is a guide and diagrams below for both engine that fit in that car. You will need to do a relearn on the sensor for the engine to run. Here is a guide and instructions on how to do the job.

Crankshaft Position System Variation Learn

Note: The Crankshaft Position System Variation Learn procedure is also required when the following service procedures have been performed, regardless of whether DTC P0315 is set:

An engine replacement
An engine control module (ECM) replacement
A crankshaft balancer replacement
A crankshaft replacement
A crankshaft position sensor replacement
Any engine repairs which disturb the crankshaft to crankshaft position sensor relationship.
Note: The ECM monitors certain component signals to determine if all the conditions are met to continue with the crankshaft position System Variation Learn Procedure.

Install a scan tool.
Monitor the ECM for DTCs with a scan tool. If other DTCs are set, except DTC P0315, refer to Diagnostic Trouble Code (DTC) List - Vehicle (See: A L L Diagnostic Trouble Codes ( DTC )Testing and InspectionDiagnostic Trouble Code DescriptionsDiagnostic Trouble Code (DTC) List - Vehicle) for the applicable DTC that set.
With a scan tool, select the Crankshaft Position System Variation Learn Procedure and perform the following:
Block drive wheels.
Set parking brake.
DO NOT apply brake pedal.
Cycle ignition from OFF to ON.
Apply and hold brake pedal for the duration of the procedure.
Start and idle engine.
Turn the air conditioning (A/C) OFF.
The vehicle must remain in Park or Neutral.
Note: 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.

Accelerate to wide open throttle (WOT) and release when the fuel cut-off occurs.
The scan tool displays Test In Progress.
The scan tool displays Learn Successful.
Verify DTC P0315 ran and passed This Ignition Cycle.
 If DTC P0315 failed or did not run This Ignition Cycle, or another DTC is present, refer to Diagnostic Trouble Code (DTC) List - Vehicle (See: A L L Diagnostic Trouble Codes ( DTC )Testing and InspectionDiagnostic Trouble Code DescriptionsDiagnostic Trouble Code (DTC) List - Vehicle) for the applicable DTC that set.
Once the Learn Procedure has successfully completed, and in order to store the crankshaft position system variation values in the ECM, turn OFF the ignition and verify all vehicle systems are OFF. This may take up to 2 minutes.

Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

Cheers
