--- | ---
DETECTION CONDITION | • Indicates the sensor signal was intermittent during the CCM.
POSSIBLE CAUSE | • Connector or terminal malfunction • IAT sensor malfunction • Harness malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has FREEZE FRAME DATA been recorded? | Yes | Go to the next step.
No | Record FREEZE FRAME DATA on the repair order, then go to the next step.
2 | VERIFY RELATED SERVICE INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available? | Yes | Perform repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
No | Go to the next step.
3 | INSPECT CONNECTOR FOR POOR CONNECTION • Turn the ignition switch off. • Disconnect PCM connector and IAT sensor connectors. • Inspect for poor connection (such as damaged, pulled-out pins, and corrosion). • Is there any malfunction? | Yes | Go to the next step.
No | Repair or replace suspected part, then go to Step 6.
4 | INTERMITTENT INSPECTION • Turn the ignition switch to the ON position (Engine off). • Access the PCM and monitor the IAT PID. • While observing the PID, perform the following: ― Tap on the sensor to simulate road shock ― Wiggle the sensor connector • Is there a large change in the voltage reading? | Yes | Inspect the IAT sensor. (See INTAKE AIR TEMPERATURE (IAT) SENSOR INSPECTION [MZI-3.7].) Replace if necessary, then go to Step 6.
No | Go to the next step.
5 | INSPECT ELECTRONIC ENGINE CONTROL WIRING HARNESS • Access the PCM and monitor the IAT PID. • While observing the PID, wiggle, shake, and bend small sections of the wiring harness while working from the sensor to the PCM. • Is there a large change in the voltage reading? | Yes | Repair if necessary, then go to Step 6.
No | Go to the next step.
6 | VERIFY TROUBLESHOOTING OF DTC P0114:00 HAS BEEN COMPLETED • Verify that all disconnected connectors reconnected. • Turn the ignition switch to the ON position (Engine off). • Clear the DTC from the PCM memory using the M-MDS. • Start the engine and run it at idle. • Retrieve DTCs using the M-MDS. • Is the PENDING CODE for this DTC present? | Yes | Repeat the inspection from Step 1. • If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [MZI-3.7].) Go to the next step.
No | Go to the next step.
7 | VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [MZI-3.7].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [MZI-3.7].)
No | Troubleshooting completed.
