(See MASS AIR FLOW (MAF) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO. 1 REMOVAL/INSTALLATION [(VIN 7 & VIN L) (US)] .)
8	INSPECT PCM CONNECTOR FOR MALFUNCTION Inspect the applicable connector and terminal. (See CONNECTOR INSPECTION .) Are the connector and terminal normal?	Yes	Go to the next step.
8		No	Repair or replace the malfunctioning location and perform the repair completion verification.
9	INSPECT MAP SENSOR FOR MALFUNCTION Inspect the applicable part. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR INSPECTION [(VIN M) (US)] .) (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR INSPECTION [(VIN 7 & VIN L) (US)] .) Is the part normal?	Yes	Go to the next step.
9		No	Repair or replace the malfunctioning location and perform the repair completion verification. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO. 2 REMOVAL/INSTALLATION [(VIN M) (US)] .) (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO. 2 REMOVAL/INSTALLATION [(VIN 7 & VIN L) (US)] .)
10	INSPECT MAF SENSOR FOR MALFUNCTION Inspect the applicable part. (See MASS AIR FLOW (MAF) SENSOR INSPECTION [(VIN M) (US)] .) (See MASS AIR FLOW (MAF) SENSOR INSPECTION [(VIN 7 & VIN L) (US)] .) Is the part normal?	Yes	Go to the next step.
10		No	Repair or replace the malfunctioning location and perform the repair completion verification. (See MASS AIR FLOW (MAF) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO. 1 REMOVAL/INSTALLATION [(VIN M) (US)] .) (See MASS AIR FLOW (MAF) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO. 1 REMOVAL/INSTALLATION [(VIN 7 & VIN L) (US)] .)
11	INSPECT INTAKE-AIR SYSTEM FOR AIR LEAKAGE Inspect for leakage in intake-air system. Is there any leakage?	Yes	Repair or replace the malfunctioning location and perform the repair completion verification.
11		No	Go to the next step.
12	INSPECT PURGE SOLENOID VALVE FOR MALFUNCTION Inspect the applicable part. (See PURGE SOLENOID VALVE INSPECTION [(VIN M) (US)] .) (See PURGE SOLENOID VALVE INSPECTION [(VIN 7 & VIN L) (US)] .) Is the part normal?	Yes	Go to the next step.

Repair completion verification 1	VERIFY THAT VEHICLE IS REPAIRED Install/connect the part removed/disconnected during the troubleshooting procedure. Clear the DTC recorded in the memory. (See CLEARING DTC .) Replicate the vehicle conditions at the time the DTC was detected using the following procedure. Start the engine. Access the following PIDs using the M-MDS: (See PID/DATA MONITOR INSPECTION .) ECT TP_RELAT ENG_RPM Warm up the engine until the ECT PID is above 70°C {158°F}. Perform the following: Depress the accelerator pedal to increase the engine speed to approx. 5, 000 rpm. Release the accelerator pedal to decrease the engine speed to idle speed. Repeat Step 1 and Step 2 operations above 3 times in succession. Perform the DTC inspection for the PCM. (See DTC INSPECTION .) Is the same Pending DTC present?	Yes	Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error. (See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW (US) .) If the CAN communication is normal, perform the diagnosis from Step 1. If the malfunction recurs, replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [(VIN M) (US)] .) (See PCM REMOVAL/INSTALLATION [(VIN 7 & VIN L) (US)] .)
Repair completion verification 1		No	Go to the next step.
Repair completion verification 2	VERIFY IF OTHER DTCs DISPLAYED Perform the DTC inspection. (See DTC INSPECTION .) Are any other DTCs displayed?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting.
Repair completion verification 2		No	DTC troubleshooting completed.
