Diagnostic Procedure

DIAGNOSTIC PROCEDURE DESCRIPTION

STEP INSPECTION RESULTS ACTION
1 RECORD VEHICLE STATUS AT TIME OF DTC DETECTION TO UTILIZE WITH REPEATABILITY VERIFICATION
NOTE:
  • Recording can be facilitated using the screen capture function of the PC.
  • Record the FREEZE FRAME DATA/snapshot data on the repair order.
 - Go to the next step.
2 VERIFY RELATED REPAIR INFORMATION AVAILABILITY
  • Verify related Service Bulletins and/or on-line repair information availability.
  • Is any related repair information available?
 Yes Perform repair or diagnosis according to the available repair information.
  • If the vehicle is not repaired, go to the next step.
No Go to the next step.
3 INSPECT MAP SENSOR/IAT SENSOR NO. 2 CONNECTOR CONDITION
  • Switch the ignition off.
  • Disconnect the MAP sensor/IAT sensor No. 2 connector.
  • Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
  • Is there any malfunction?
 Yes Repair or replace the connector and/or terminals, then go to Step 8.
No Go to the next step.
4 INSPECT PCM CONNECTOR CONDITION
  • Disconnect the PCM connector.
  • Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
  • Is there any malfunction?
 Yes Repair or replace the connector and/or terminals, then go to Step 8.
No Go to the next step.
5 INSPECT MAP SENSOR CIRCUIT FOR SHORT TO GROUND
  • Verify that the MAP sensor/IAT sensor No. 2 and PCM connectors are disconnected.
  • Inspect for continuity between the following terminals (wiring harness-side) and body ground:
    • MAP sensor/IAT sensor No. 2 terminal C
      • MAP sensor/IAT sensor No. 2 terminal D
  • Is there continuity?
 Yes Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:
  • MAP sensor/IAT sensor No. 2 terminal C-PCM terminal 1BO
  • MAP sensor/IAT sensor No. 2 terminal D-PCM terminal 1BW

If there is a common connector:
  • Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground.
  • Repair or replace the malfunctioning part.

If there is no common connector:
  • Repair or replace the wiring harness which has a short to ground.

Go to Step 8.
No Go to the next step.
6 INSPECT MAP SENSOR SIGNAL CIRCUIT AND GROUND CIRCUIT FOR SHORT TO EACH OTHER
  • Verify that the MAP sensor/IAT sensor No. 2 and PCM connectors are disconnected.
  • Inspect for continuity between MAP sensor/IAT sensor No. 2 terminals D and A (wiring harness-side).
  • Is there continuity?
 Yes Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:
  • MAP sensor/IAT sensor No. 2 terminal D-PCM terminal 1BW
  • MAP sensor/IAT sensor No. 2 terminal A-PCM terminal 1BX

If there is a common connector:
  • Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to each other.
  • Repair or replace the malfunctioning part.

If there is no common connector:
  • Repair or replace the wiring harness which has a short to each other.

Go to Step 8.
No Go to the next step.
7 INSPECT MAP SENSOR Yes Replace the MAP sensor/IAT sensor No. 2, then go to the next step.
(See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO. 2 REMOVAL/INSTALLATION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .)
No Go to the next step.
8 VERIFY DTC TROUBLESHOOTING COMPLETED Yes Repeat the inspection from Step 1.
Go to the next step.
No Go to the next step.
9 VERIFY AFTER REPAIR PROCEDURE Yes Go to the applicable DTC inspection.
(See DTC TABLE [PCM (SKYACTIV-G 2.0, SKYACTIV-G 2.5)] .)
No DTC troubleshooting completed.
