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". (See AFTER REPAIR PROCEDURE [AJ].) • Is any DTC present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [AJ] (VIN: JM0 LW10J300 301406-, JMZ LW69J7*# 307683-, JM8 LW28J**# 301514-, JM8 LW28A**# 301514- (Assumed)).)
No | Troubleshooting completed.
