Resistance Inspection

1.  Remove the battery cover. (See BATTERY REMOVAL/INSTALLATION [13B-MSP].)

2.  Disconnect the negative battery cable.

3.  Disconnect the MAF/IAT sensor connector.

4.  Verify that the resistance between MAF sensor terminals D and E is as indicated in the table while blowing hot air gradually into the IAT sensor part built into the MAF sensor.
