INSPECT MAP SENSOR/BOOST AIR TEMPERATURE SENSOR CONNECTOR CONDITION
• Switch the ignition to off.
• Disconnect the MAP sensor/boost air temperature sensor connector.
• Inspect for poor connection (such as damaged/pulled-out pins, and corrosion).
• Is there any malfunction?
|
Yes
|
Repair or replace the connector and/or terminals, then go to Step 9.

INSPECT MAP SENSOR CIRCUIT FOR SHORT TO GROUND
• MAP sensor/boost air temperature sensor connector is disconnected.
• Inspect for continuity between the following terminals (wiring harness-side) and body ground:
-
― MAP sensor/boost air temperature sensor terminal C
― MAP sensor/boost air temperature sensor terminal D
• Is there continuity?
|
Yes
|
If the short to ground circuit could be detected:
• Repair or replace the wiring harness for a possible short to ground.
If the short to ground circuit could not be detected:
• Replace the PCM (short to ground in PCM internal circuit).
Go to Step 9.

|
INSPECT MAP SENSOR SIGNAL CIRCUIT AND GROUND CIRCUIT FOR SHORT TO EACH OTHER
• MAP sensor/boost air temperature sensor and PCM connectors are disconnected.
• Inspect for continuity between MAP sensor/boost air temperature sensor terminals D and A (wiring harness-side).
• Is there continuity?
|
Yes
|
Repair or replace the wiring harness for a possible short to each other, then go to Step 9.
|
|
No
|
Go to the next step.

• Is there continuity?
|
Yes
|
Go to the next step.
|
|
No
|
Repair or replace the wiring harness for a possible open circuit, then go to Step 9.
|
|
8
|
INSPECT MAP SENSOR

VERIFY DTC TROUBLESHOOTING COMPLETED
• Make sure to reconnect all disconnected connectors.
• Clear the DTC from the PCM memory using the M-MDS.
• Perform the KOEO or KOER self test.
• Is the same DTC present?
|
Yes
|
Repeat the inspection from Step 1.
• If the malfunction recurs, replace the PCM.
Go to the next step.
|
|
No
|
Go to the next step.
|
