Function Inspection
- Connect the M-MDS to the DLC-2.
- Switch the ignition ON (engine off).
- Display the PID IAT. (See ON-BOARD DIAGNOSTIC TEST [PCM (VIN L (WITHOUT CYLINDER DEACTIVATION))] .) (See PCM INSPECTION [VIN L (WITHOUT CYLINDER DEACTIVATION)] .)
- Compare the voltage and temperature indications for the PID IAT with the standard in the table indicated below.
- If they do not match the standard, replace the MAF sensor/IAT sensor No. 1. (See MASS AIR FLOW (MAF) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO. 1 REMOVAL/INSTALLATION [VIN L (WITHOUT CYLINDER DEACTIVATION)] .)
