DTC P0328 [AJ] (VIN: JM0 LW10J300 301406-, JMZ LW69J7*# 307683-, JM8 LW28J**# 301514-, JM8 LW28A**# 301514- (Assumed))

BME010200100W17

DTC P0328

Knock sensor circuit high input

DETECTION CONDITION

• PCM monitors input signal from knock sensor when engine is running. If input voltage at PCM terminal between 81 and 3 is above 3.75 V, PCM determines that knock sensor circuit has malfunction.
Diagnostic support note
• This is a continuous monitor (CCM).
• The MIL illuminates if the PCM detects the above malfunction condition in the first drive cycle.
• PENDING CODE is available if the PCM detects the above malfunction condition.
• FREEZE FRAME DATA is available.
• DTC is stored in PCM memory.

POSSIBLE CAUSE

• Knock sensor malfunction
• Connector or terminal malfunction
• Short to power circuit in wiring between knock sensor terminal A and PCM terminal 81
• Short to power circuit in wiring between knock sensor terminal B and PCM terminal 3
• PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION

1
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
• Has FREEZE FRAME DATA been recorded?
Yes
Go to the next step.
No
Record FREEZE FRAME DATA on repair order, then go to the next step.
2
VERIFY RELATED REPAIR INFORMATION AVAILABILITY
• Check for related Service Information and /or on-line repair information availability.
• Is any related repair Information available?
Yes
Perform repair or diagnosis according to available repair Information.
• If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
CHECK KNOCK SIGNAL CIRCUIT FOR OPEN CIRCUIT
• Turn the ignition switch off.
• Disconnect knock connector.
• Turn the ignition switch to the ON position (Engine off).
• Measure voltage between KS terminal A (harness-side) and body GND.?
• Is voltage approx. 5 V?
Yes
Go to Step 5.
No
Go to the next step.
4
CHECK PCM CONNECTOR
• Disconnect PCM connector.
• Check for poor connection (damaged, pulled-out terminals, corrosion, etc.).
• Is there any malfunction?
Yes
Repair or replace the terminal, then go to Step 6.
No
Repair or replace harness for open, then go to Step 6.
5
CHECK KNOCK SENSOR
• Measure resistance between knock sensor terminal A (part-side) and sensor body.
• Is resistance approx. 560 kilohms?
Yes
Go to the next step.
No
Replace knock sensor, then go to the next step.
6
VERIFY TROUBLESHOOTING OF DTC P0328 COMPLETED
• Make sure to connect all disconnected connectors.
• Clear the DTC from the PCM memory using the WDS or equivalent.
• Start engine.
• Is same DTC present?
Yes
Replace PCM, then go to the next step.
No
Go to the next step.
7
VERIFY AFTER REPAIR PROCEDURE
• Perform the "After Repair Procedure".
• Is any DTC present?
Yes
Go to the applicable DTC inspection.
No
Troubleshooting completed.
