DTC P0327[MTX, LF ATX (FS5A-EL)]

id0102b4806700

DTC P0327

KS circuit low input
DETECTION CONDITION
•  The PCM monitors input signal from the KS when the engine is running. If the input voltage between PCM terminals for the KS circuit is below 0.06 V the PCM determines that the KS circuit has malfunction.
Diagnostic support note
•  This is a continuous monitor (CCM).
•  The MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.
•  FREEZE FRAME DATA is available.
•  DTC is stored in the PCM memory.
POSSIBLE CAUSE
•  KS malfunction
•  Connector or terminal malfunction
•  Open circuit or short to ground in wiring harness between KS connector terminal A and PCM terminal 2U
•  Open circuit or short to ground in wiring harness between KS connector terminal B and PCM terminal 2V
•  Short KS two wires
•  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 the FREEZE FRAME DATA on the repair order, then go to the next step.
2
VERIFY RELATED SERVICE INFORMATION AVAILABILITY
•  Verify related Service Information availability.
•  Is any related Service Information available?
Yes
Perform repair or diagnosis according to the available Service Information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
INSPECT KS CONNECTOR TERMINAL
•  Turn the ignition switch off.
•  Disconnect the KS connector.
•  Inspect for poor connection at terminals A and B (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair the terminal, then go to Step 9.
No
Go to the next step.
4
INSPECT KS
•  Perform KS inspection.
•  Is KS normal?
Yes
Go to the next step.
No
Replace the KS, then go to the next step.
5
INSPECT KS CIRCUITS FOR SHORT TO GROUND
•  Inspect the continuity between following terminals:
―  KS female terminal A and body ground
―  KS female terminal B and body ground
•  Is there continuity?
Yes
Repair or replace suspected wiring harness, then go to Step 9.
No
Go to the next step.
6
INSPECT FOR SHORT CIRCUITS
•  Inspect for continuity between KS female terminals A and B.
•  Is there continuity?
Yes
Repair or replace the wiring harness, then go to Step 9.
No
Go to the next step.
7
INSPECT PCM CONNECTOR TERMINAL
•  Turn the ignition switch off.
•  Disconnect the PCM connector.
•  Inspect for poor connection at terminals 2U and 2V (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair terminal, then go to Step 9.
No
Go to the next step.
8
INSPECT KS CIRCUITS FOR OPEN CIRCUIT
•  Disconnect the PCM connector.
•  Inspect for continuity between the following terminals:
―  KS female terminal A and PCM terminal 2U
―  KS female terminal B and PCM terminal 2V
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness, then go to the next step.
9
VERIFY TROUBLESHOOTING OF DTC P0327 COMPLETED
•  Make sure to reconnect all disconnected connectors.
•  Clear the DTC from the memory using the M-MDS.
•  Start the engine.
•  Is the same DTC present?
Yes
Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION[LF, L3].)
No
Go to the next step.
10
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC troubleshooting.
(See DTC TABLE[MTX, LF ATX (FS5A-EL)].)
No
Troubleshooting completed.
