DTC DETECTION LOGIC
DTC No. | CONSULT screen terms (Trouble diagnosis content) | DTC detecting condition | Possible cause |
P0327 | KNOCK SEN/CIRC-B1 (Knock sensor 1 circuit low bank 1) | An excessively low voltage from the knock sensor is sent to ECM. |
|
P0328 | KNOCK SEN/CIRC-B1 (Knock sensor 1 circuit high bank 1) | An excessively high voltage from the knock sensor is sent to ECM. |
DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10 V at idle.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
Is 1st trip DTC detected? YES >> Proceed to EC-275, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK KNOCK SENSOR GROUND CIRCUIT
Is the inspection result normal? YES >> GO TO 2.
NO >> Repair or replace error-detected parts.
2.CHECK KNOCK SENSOR INPUT SIGNAL CIRCUIT
Is the inspection result normal? YES >> GO TO 3.
NO >> Repair open circuit or short to ground or short to power in harness or connectors.
3.CHECK KNOCK SENSOR
Check knock sensor. Refer to EC-276, "Component Inspection (KS)".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Replace knock sensor. Refer to EM-94, "Exploded View".
Component Inspection (KS)
1.CHECK KNOCK SENSOR
NOTE:
It is necessary to use an ohmmeter which can measure more than 10 MΩ.
CAUTION:
Do not use any knock sensors that have been dropped or physically damaged. Use only new ones.
Is the inspection result normal? YES >> INSPECTION END
NO >> Replace knock sensor. Refer to EM-94, "Exploded View".
