MASS AIR FLOW (MAF) SENSOR INSPECTION [13B-MSP]
NOTE:
Before performing the following inspection, make sure to follow the troubleshooting
flowchart. (See
Visual Inspection
1. Visually inspect the MAF/IAT sensor for the following:
Damage, cracks
Rusted sensor terminal
Bent sensor terminal
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 even though the related harnesses have no malfunction,
replace the MAF/IAT sensor. (See
TEMPERATURE (IAT) SENSOR REMOVAL/INSTALLATION
Circuit Open/Short Inspection
FOREWORD [13B-MSP].)
If there is any malfunction, replace the MAF/IAT sensor. (See
MASS AIR FLOW (MAF)/INTAKE AIR TEMPERATURE (IAT)
SENSOR REMOVAL/INSTALLATION
If the monitor item condition (reference) is not within the
specification even though there is no malfunction, perform the
"Circuit Open/Short Inspection". (See
Inspection.)
