MASS AIR FLOW (MAF) SENSOR INSPECTION [13B-MSP]

id0140g1800700

Visual Inspection

1.  Visually inspect the MAF/IAT sensor for the following:

•  Damage, cracks

•  Rusted sensor terminal

•  Bent sensor terminal

―  If there is any malfunction, repair or replace the MAF/IAT sensor. (See MASS AIR FLOW (MAF)/INTAKE AIR TEMPERATURE (IAT) SENSOR REMOVAL/INSTALLATION [13B-MSP].)

Voltage Inspection

1.  Remove the MAF/IAT sensor without disconnect the MAF/IAT sensor connector.

2.  Turn the ignition switch to ON position.

3.  As the air gradually approaches the MAF detection part of the MAF/IAT sensor, verify that the voltage at PCM terminal 1AK (M-MDS PID: MAF) varies.

•  If it cannot be verified, replace the MAF/IAT sensor. (See MASS AIR FLOW (MAF)/INTAKE AIR TEMPERATURE (IAT) SENSOR REMOVAL/INSTALLATION [13B-MSP].)
