Diagnostic Procedure

Step

Inspection

Results

Action

1

INSPECT FUEL FILTER FOR WATER ACCUMULATION OVER SPECIFIED AMOUNT MALFUNCTION

•  Remove water from filter.

•  Refer to the [MEMORY CLEARING PROCEDURE] and clear the DTC.

•  Perform the KOEO or KOER self-test.

•  Has DTC P1140:00 been recorded?

Yes

Go to the next step.

No

Go to Step 7.

2

INSPECT SEDIMENTOR SWITCH CONNECTOR CONDITION

•  Switch the ignition OFF.

•  Disconnect the sedimentor switch connector.

•  Inspect the connector engagement and connection condition, and inspect the terminals for damage, deformation, corrosion, or disconnection.

•  Is the connector normal?

Yes

Go to the next step.

No

Repair or replace the connector, then go to Step 6.

3

INSPECT SEDIMENTOR SWITCH CIRCUIT FOR SHORT TO GROUND

•  Verify that the sedimentor switch connector is disconnected.

•  Inspect for continuity between sedimentor switch terminal A (vehicle wiring harness side) and body ground.

•  Is there continuity?

Yes

•  Refer to the wiring diagram and verify if there is a common connector between sedimentor switch terminal A and PCM terminal 2F.

If there is a common connector:

―  Inspect the common connector and terminals for corrosion, damage, or disconnection and the common wiring harnesses for short to ground to determine the malfunctioning location.

―  Repair or replace the malfunctioning location.

If there is no common connector:

―  Repair or replace the wiring harness which is shorted to ground.

•  Go to Step 6.

No

Go to the next step.

4

INSPECT PCM CONNECTOR CONDITION

•  Disconnect the PCM connector.

•  Inspect the connector engagement and connection condition, and inspect the terminals for damage, deformation, corrosion, or disconnection.

•  Is the connector normal?

Yes

Go to the next step.

No

Repair or replace the connector, then go to Step 6.

5

INSPECT SEDIMENTOR SWITCH

•  Inspect the sedimentor switch.

•  Is the sedimentor switch normal?

Yes

Go to the next step.

No

Replace the fuel filter, then go to the next step.

6

VERIFY THAT REPAIRS HAVE BEEN COMPLETED

•  Reconnect all the disconnected connectors.

•  Refer to the [MEMORY CLEARING PROCEDURE] and clear the DTC.

•  Display the DTCs using the M-MDS.

•  Has DTC P1140:00 been recorded?

Yes

Repeat the inspection from Step 1.

•  If the malfunction recurs, replace the PCM, then go to the next step.

No

Go to the next step.

7

VERIFY OTHER DTCs

•  Has any other DTC or pending code been stored?

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

No

DTC troubleshooting completed.
