Circuit/System Testing: P0324

WARNING: This page is about a different variant/trim than selected.

This DTC indicates an internal control module circuitry failure. Replace the ECM.

P0325, P0327, P0328, P0330, P0332, and P0333

Turn OFF the ignition.
Disconnect the KS inline connector at the back of the engine.
Measure for infinite resistance from the KS signal circuit on the sensor side of the KS harness connector to a good ground and from the KS low reference circuit on the sensor side of the KS harness connector to a good ground with the DMM.
- If either of the circuits are grounded, repair the short to ground.
Measure for infinite resistance from the KS signal circuit on the ECM side of the KS harness connector to a good ground and from the KS low reference circuit on the ECM side of the KS harness connector to a good ground with the DMM.
- If either of the circuits are grounded, repair the short to ground.
Turn ON the ignition, with the engine OFF.
On the control module side of the KS harness connector, measure for less than 4.2 DC volts from the KS low reference circuit to a good ground with a DMM.
- If the KS low reference circuit measures more than 4.2 volts, inspect for a short to voltage. If the circuit tests normal, replace the control module.
On the control module side of the KS harness connector, measure for less than 4.2 DC volts from the KS signal circuit to a good ground with a DMM.
- If the KS signal circuit measures more than 4.2 volts, inspect for a short to voltage. If the circuit tests normal, replace the control module.
Test the KS signal circuit and the KS low reference circuit for the following conditions on the ECM side of the harness connector and on the sensor side of the harness connector:
- An open
- High resistance
- Shorted to each other or any other circuit.
- If the circuits and the sensor test normal, replace the control module.

P0326

IMPORTANT: If DTC P0335 or P0336 are also set, diagnose those DTCs first.

Inspect for a loose or broken vehicle accessory or accessory bracket.
Inspect for excessive engine mechanical noise.
