Function Inspection

Connect the M-MDS to the DLC-2.
Switch the ignition ON (engine off).
Display the PID MAF. (See PID/DATA MONITOR INSPECTION .)
Compare the voltage and flow rate indications for the PID MAF 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 .)
