WARNING: This page is about a different variant/trim than selected.

Step 1-2
- Perform an inspection of the connectors and wiring harnesses between the MAF sensor/IAT sensor No. 1 and the PCM.
Step 3
- Perform a unit inspection of the MAF sensor/IAT sensor No. 1.
Repair completion verification
- Verify that the primary malfunction is resolved and there are no other malfunctions.

P0110-00 (PCM (PYUL)) DIAGNOSTIC PROCEDURE

Step	Inspection	Results	Action
1	VERIFY IF MAF SENSOR/IAT SENSOR No. 1 IS INSTALLED POORLY Verify the MAF sensor/IAT sensor No. 1 installation condition. (Refer to [MASS AIR FLOW (MAF) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO. 1 REMOVAL/INSTALLATION ] in Service Information). Is the installation condition normal?	Yes	Go to the next step.
1		No	Correctly install the MAF sensor/IAT sensor No. 1 and perform the repair completion verification 1. (Refer to [MASS AIR FLOW (MAF) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO. 1 REMOVAL/INSTALLATION ] in Service Information).
2	PURPOSE: INSPECT WIRING HARNESS (INCLUDING CONNECTOR/TERMINAL) BETWEEN IAT SENSOR No. 1 AND PCM FOR MALFUNCTION Inspect the applicable circuit. (See CIRCUIT INSPECTION ) (See CONNECTOR INSPECTION ) Is the circuit normal?	Yes	Go to the next step.
2		No	Repair or replace the malfunctioning location and perform the repair completion verification 1.
3	PURPOSE: VERIFY MAF/IAT SENSOR No. 1 FOR MALFUNCTION Inspect the applicable part. (Refer to [MASS AIR FLOW (MAF) SENSOR INSPECTION ] in Service Information). (Refer to [INTAKE AIR TEMPERATURE (IAT) SENSOR INSPECTION ] in Service Information). Is the part normal?	Yes	Go to the next step.
3		No	Repair or replace the malfunctioning location and perform the repair completion verification 1. (Refer to [MASS AIR FLOW (MAF) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO. 1 REMOVAL/INSTALLATION ] in Service Information).
Repair completion verification 1	PURPOSE: 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. Perform the KOEO or KOER self test. (See DTC INSPECTION ) 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 MALFUNCTION DIAGNOSIS FLOW [CONTROLLER AREA NETWORK (CAN)] ) 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. (Refer to [PCM REMOVAL/INSTALLATION ] in Service Information).
Repair completion verification 1		No	Go to the next step.
Repair completion verification 2	PURPOSE: VERIFY IF OTHER DTCs DISPLAYED Perform the DTC inspection. (See DTC INSPECTION ) Are any other DTCs displayed?	Yes	Repair or replace the malfunctioning location according to the applicable DTC troubleshooting.
Repair completion verification 2		No	DTC troubleshooting completed.
