P0320 - Ignition Failure Sensor Circuit Malfunction

It sounds to me like you might just have a bad ignition failure sensor. This is very common; with the engine running check for battery voltage to the ignition failure sensor on the Pink wire, less than 0.05 volts on the Black wire, and battery voltage from the ignition failure sensor on the Black/White wire. Check for battery voltage to the coils on the Black/White wire and verify the voltage is the same as the voltage on the Pink wire at the ignition failure sensor. With the engine running, scope the signal on the Yellow/Red wire from the ignition failure sensor (click over image for zoom).

Potential Causes:
Ignition Failure Sensor
Ignition Failure Sensor Wiring

Code po320 and code p1631


The Code 1631 is for no Alternator output. The Code 0320 is for a lack of power in the ignition coil circuit. Means the ECM is not recording a signal from the igniiton coil path. The coil path means the crankshaft sensor, the camshaft sensor, etc. Basically no power is going through the wires to reach the ECM.
