F–90 ON-BOARD DIAGNOSTIC End Of Sie DTC P0111 A6E397001084W13 Diagnostic procedure 6 VERIFY MAP SENSOR SIGNAL CIRCUIT FOR • Inspect for continuity between MAP sensor terminal D and C (harness-side). • Is there any continuity? Yes Repair or replace suspected harness, then go to Step 8. No Go to next step. 7 VERIFY MAP SENSOR SIGNAL CIRCUIT FOR • Inspect continuity between MAP sensor terminal D (harness-side) and PCM terminal 1J • Is there any continuity? Yes Go to next step. No Repair or replace suspected harness, then go to next step. 8 VERIFY TROUBLESHOOTING OF DTC P0108 • Make sure to reconnect all disconnected connectors. • Turn ignition key to ON (Engine OFF). • Clear DTC from memory using WDS or equivalent. • Perform KOEO/KOER self-test. .) • Is same DTC present? Yes Replace PCM, then go to next step. (See No Go to next step. 9 VERIFY AFTER REPAIR PROCEDURE • Perform “After Repair Procedure”. • Is there any DTC present? Yes Go to applicable DTC troubleshooting. (See .) No Troubleshooting completed. STEP INSPECTION ACTION DTC P0111 IAT circuit performance problem DETECTION CONDITION • If intake air temperature is higher than engine coolant temperature by 40 °C {104 °F} with ignition key on, the PCM determines that there is a IAT sensor performance problem. Diagnostic support note • This is a continuous monitor (CCM). • MIL illuminates if PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM. • PENDING CODE is available if PCM detects the above malfunction condition during first drive cycle. • FREEZE FRAME DATA is available. • DTC is stored in PCM memory. POSSIBLE CAUSE • IAT sensor malfunction • Poor connection at MAF/IAT sensor or PCM connector • PCM malfunction STEP INSPECTION ACTION 1 VERIFY FREEZE FRAME DATA HAS BEEN • Has FREEZE FRAME DATA been recorded? Yes Go to next step. No Record FREEZE FRAME DATA on repair order, then go to 2 VERIFY RELATED SERVICE INFORMATION • Check for related Service Information availability. • Is any related Service Information available? Yes Perform repair or diagnosis according to available Service Information. • If vehicle is not repaired, go to next step. No Go to next step. 3 INSPECT POOR CONNECTION OF MAF/IAT • Turn ignition key to OFF. • Disconnect MAF/IAT sensor connector. • Inspect for poor connection (damaged, pulled- out pins, corrosion, etc.). • Are there any malfunctions? Yes Repair or replace terminal, then go to Step 6. No Go to next step. 4 INSPECT IAT SENSOR • Inspect IAT sensor. F–50 INTAKE AIR TEMPERATURE (IAT) ) • Is IAT sensor okay? Yes Replace MAF/IAT sensor, then go to Step 6. No Go to next step. |
