MASS AIR FLOW (MAF) SENSOR INSPECTION
A6E394013210W01
Voltage Inspection
Note
•
Perform the following inspection only when directed.
1. Visually inspect for the following on the MAF sensor.
•
Damage
•
Cracks
•
Terminal bends
•
Terminal rust
— If any of the above are found, replace the MAF sensor.
— If the MAF PID value is out of specification, carry out the “Circuit Open/Short Inspection”.
Circuit Open/Short Inspection
1. Disconnect the PCM connector. (See
F–43 PCM
REMOVAL/INSTALLATION
.)
2. Disconnect the MAF sensor connector.
3. Inspect the following wiring harnesses for open or
short. (Continuity check)
Open circuit
•
If there is no continuity, the circuit is open. Repair
or replace the harness.
— MAF sensor terminal A (harness-side) and
main relay terminal C (harness-side)
— MAF sensor terminal B (harness-side) and
PCM terminal 2AC (harness-side)
— MAF sensor terminal C (harness-side) and
PCM terminal 1P (harness-side)
Short circuit
•
If there is continuity, the circuit is shorted. Repair or replace the harness.
— MAF sensor terminal A (harness-side) and body GND
— MAF sensor terminal C (harness-side) and power supply
— MAF sensor terminal C (harness-side) and body GND
— MAF sensor terminal B (harness-side) and power supply

THROTTLE POSITION (TP) SENSOR INSPECTION
A6E394018910W01
Note
•
Perform the following inspection only when directed.
Resistance Inspection
1. Perform the following test only when directed.
•
If as specified but TP PID value is out of specification, inspect resistance of TP sensor.
•
If not as specified, inspect the following:
— Accelerator cable free play (See
F–16 ACCELERATOR CABLE INSPECTION/ADJUSTMENT
.)
2. Disconnect the TP sensor connector.
3. Verify that the resistance between TP sensor
terminals A and B changes smoothly while
opened and closed the throttle valve slowly.
•
If not verified, replace TP sensor.
4. Measure the resistance between TP sensor
terminals A and C using an ohmmeter.
•
If not as specified, replace the TP sensor.
•
If as specified, but TP PID value is out of
specification, perform the “Circuit Open/Short
Inspection”.
