Diagnostic Trouble Code (DTC) Charts and Descriptions

P0322 - Ignition/Distributor Engine Speed Input Circuit No Signal

Description: This DTC sets when the crankshaft position (CKP) sensor profile ignition pickup (PIP) pulse is missing for

greater than a calibrated number of camshaft revolutions when the camshaft speed exceeds the equivalent speed of engine idle.

Possible Causes: • CKP+ circuit intermittent open (VR type)

• CKP- circuit open (VR type)

• CKP circuit open (Hall effect)

• VREF circuit open (Hall effect)

• SIGRTN circuit open (Hall effect)

• CKP+ circuit short to voltage (VR type)

• CKP- circuit short to voltage (VR type)

• CKP circuit short to voltage (Hall effect)

• VREF circuit short to voltage (Hall effect)

• SIGRTN circuit short to voltage (Hall effect)

• CKP+ circuit short to ground (VR type)

• CKP- circuit short to ground (VR type)

• CKP circuit short to ground (Hall effect)

• VREF circuit short to ground (Hall effect)

• SIGRTN circuit short to ground (Hall effect)

• Damaged CKP sensor

• CKP sensor incorrectly installed

• Incorrect, damaged or corroded connections

Diagnostic Aids: An inactive CKP signal causes a no start condition. Monitor the RPM PID while cranking the engine. A value of

0 RPM indicates a CKP concern.

Application Key On Engine Off Key On Engine Running Continuous Memory

All GO to Pinpoint Test A.

P0325 - Knock Sensor 1 Circuit (Bank 1)

Description: This DTC sets when the voltage goes outside a calibrated level. The knock sensor 1 (KS1) detects vibrations

upon increase and decrease in engine RPM. The KS1 generates a voltage based on this vibration.

Possible Causes: • KS1+ circuit open

• KS1- circuit open

• KS1+ circuit short to voltage

• KS1- circuit short to voltage

• KS1+ circuit short to ground

• KS1- circuit short to ground

• Damaged KS1

Diagnostic Aids: A KS1 voltage greater than 0.5 volt with the ignition ON, engine OFF, indicates a concern is present.

The vehicle may need to be driven for several minutes to set this DTC.

Application Key On Engine Off Key On Engine Running Continuous Memory

All GO to Pinpoint Test DG.

P0326 - Knock Sensor 1 Circuit Range/Performance (Bank 1)

Description: This DTC sets when the voltage goes outside a calibrated level. The knock sensor 1 (KS1) detects vibrations

upon increase and decrease in engine RPM. The KS1 generates a voltage based on this vibration.

Possible Causes: • KS1+ circuit open

• KS1- circuit open

• KS1+ circuit short to voltage

• KS1- circuit short to voltage

• KS1+ circuit short to ground

• KS1- circuit short to ground

• Damaged KS1

Diagnostic Aids: A KS1 voltage greater than 0.5 volt with the ignition ON, engine OFF, indicates a concern is present.

The vehicle may need to be driven for several minutes to set this DTC.

Application Key On Engine Off Key On Engine Running Continuous Memory

All GO to Pinpoint Test DG.
