GMC Repair: crank position sensor, gmc savana van, negative battery cable


Question
gmc savana van 5.7, How to re-learn sensor after install, Thanks, Dave

Answer
Disconnect the negative cable from the battery.

Wait 10 minutes for the on-board computer's power supply to discharge. This will erase the stored codes and reset the check engine light.

Reconnect the negative battery cable. Test drive the car for 15 minutes at a variety of speeds and traffic conditions to complete the computer's relearn process and ensure the engine runs properly.
