DTC P0669:00 [PCM (SKYACTIV-D 2.2)]

id0102j5706400

DTC P0669:00

PCM internal temperature sensor circuit high input

DETECTION CONDITION

•  PCM temperature is abnormally high when the following conditions are met:

―  Battery voltage: 8—16 V

―  0.5 s have elapsed after ignition is switched ON (engine on)

Diagnostic support note

•  This is a continuous monitor (CCM).

•  The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle.

•  FREEZE FRAME DATA/Snapshot data is available.

•  DTC is stored in the PCM memory.

FAIL-SAFE FUNCTION

Not applicable

POSSIBLE CAUSE

•  PCM ambient temperature is abnormally low

•  PCM malfunction

―  PCM temperature sensor malfunction

Diagnostic Procedure

Step

Inspection

Results

Action

1

RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION

Note

•  Recording can be facilitated using the screen capture function of the PC.

•  Record the freeze frame data/snap shot data.

Go to the next step.

2

INSPECT PCM CONNECTOR CONDITION

•  Switch the ignition OFF.

•  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 the next step.

3

VERIFY THAT REPAIRS HAVE BEEN COMPLETED

•  Reconnect all the disconnected connectors.

•  Refer to the [MEMORY CLEARING PROCEDURE] and clear the DTC.
(See CLEARING DTC [PCM (SKYACTIV-D 2.2)].)

•  Switch the ignition ON (engine off) and wait for 30 s.

•  Display the DTCs using the M-MDS.
(See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 2.2)].)

•  Has DTC P0669:00 been recorded?

Yes

Replace the PCM, then go to the next step.

(See PCM REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)

No

Go to the next step.

4

VERIFY OTHER DTCs

•  Has any other DTC or pending code been stored?

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

(See DTC TABLE [PCM (SKYACTIV-D 2.2)].)

No

DTC troubleshooting completed.
