Is any problem corrosion found?	Yes	Repair or replace the suspected terminal or MAF sensor, then go to Step 6. (See MASS AIR FLOW (MAF)/INTAKE AIR TEMPERATURE (IAT) SENSOR REMOVAL/INSTALLATION .)
4		No	Go to the next step.
5	INSPECT PCM CONNECTOR FOR POOR CONNECTION Disconnect the PCM connector. Inspect for poor connection (such as damaged/pulled-out pins, corrosion.). Is there any malfunction?	Yes	Repair terminal, then go to the next step.
5		No	Go to the next step.
6	VERIFY TROUBLESHOOTING OF DTC P0101 COMPLETED Make sure to connect all disconnected connectors. Turn the ignition switch to ON position (Engine off). Clear the DTC from PCM memory using the WDS or equivalent. Start the engine. Warm-up engine until ECT PID is above -200°C {-392°F}. Idle engine for 5 s or more. CAUTION: While performing the Drive Mode, always operate the vehicle in a safe and lawful manner. Drive the vehicle under the following two conditions: Condition 1 TP PID: 50-87.5% RPM PID: above 500 rpm 4th gear (MT), D range (AT) Condition 2 TP PID: above 80% RPM PID: below 2,000 rpm Gear in Is PENDING CODE for this the DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION .)
6		No	Go to the next step.
