Conditions for Clearing the DTC
DTCs P0324, P0325, P0326, P0327, P0328, P0330, P0332, and P0333 are Type B codes.
Diagnostic Aids
* Inspect the KS for physical damage. A KS that is dropped or damaged may cause a DTC to set.
* Inspect the KS for proper installation. A KS that is loose or over torqued may cause a DTC to set.
* The KS mounting surface should be free of burrs, casting flash, and foreign material.
* The KS must be clear of hoses, brackets, and engine electrical wiring.

Circuit/System Verification
1. Engine at operating temperature, observe DTC information with a scan tool. DTC P0324, P0325, P0326, P0327, P0328, P0330, P0332, or
P0333 should not set.
2. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the
conditions that you observed from the Freeze Frame/Failure Records data.

P0324
Note: If DTC P0325, P0326, P0327, P0328, P0330, P0332, or P0333 are also set, diagnose those DTCs first.
DTC P0324 indicates an internal control module circuitry failure. Replace the ECM.
P0325, P0326, P0327, P0328, P0330, P0332, P0333
1. Ignition OFF, disconnect the affected KS.
2. Ignition OFF. Connect a DMM to both KS signal circuits, terminals A and B, at the affected KS. Set the DMM to the 400 mV AC scale,
select the Hz mode. Let the reading stabilize at 0 Hz.
Note: DO NOT tap on plastic engine components.
