Resistance Inspection

NOTE:
  • Before performing the following inspection, make sure to follow the procedure as indicated in the troubleshooting flowchart. (See HOW TO USE THIS MANUAL ).
  1. Disconnect the MAF/IAT sensor.
  2. Measure the resistance between the MAF/IAT sensor terminals D and E using a tester.
    • If not as specified, replace the MAF/IAT sensor. (See INTAKE AIR SYSTEM REMOVAL/INSTALLATION ).
    • If the MAF/IAT sensor is normal, but the PID is out of specification, perform the "Circuit Open/Short Inspection".
