PINPOINT TEST G531332p1 : MASS AIR
FLOW (MAF) SENSOR CIRCUIT
RANGE/PERFORMANCE, HIGH/LOW
VOLTAGE
G531332t1 : CHECK THE MAF SENSOR SENSING CIRCUIT FOR HIGH
RESISTANCE
1. Key off. 2. Disconnect the ECM electrical connector, PI300. 3. Disconnect the MAF sensor electrical
connector, PI14. 4. Measure the resistance between:
ECM connector PI300, harness side MAF connector PI14, harness side
Pin 70
Pin 03
Is the resistance greater than 5 ohms?
-> Yes
REPAIR the high resistance circuit. For additional information, refer to the wiring diagrams. CLEAR the
DTC. TEST the system for normal operation.
-> No
GO to Pinpoint Test G531332t2.
G531332t2 : CHECK THE MAF SENSOR SENSING CIRCUIT FOR SHORT
CIRCUIT TO POWER
1. Key on, engine off. 2. Measure the voltage between:
www.
MAF connector PI14, harness side
Battery
Pin 03
Negative terminal
Is the voltage greater than 3 volts?
-> Yes
REPAIR the short circuit. For additional information, refer to the wiring diagrams. CLEAR the DTC.
TEST the system for normal operation.
-> No
GO to Pinpoint Test G531332t3.
G531332t3 : CHECK THE MAF SENSOR SENSING CIRCUIT FOR SHORT
CIRCUIT TO GROUND
1. Key off. 2. Measure the resistance between:
MAF connector PI14, harness side
Battery
Pin 03
Negative terminal
Is the resistance less than 10,000 ohms?
-> Yes
REPAIR the short circuit. For additional information, refer to the wiring diagrams. CLEAR the DTC.
TEST the system for normal operation
-> No
GO to Pinpoint Test G531332t4.
G531332t4 : CHECK THE MAF SENSOR SUPPLY CIRCUIT VOLTAGE
1. Reconnect the ECM electrical connector, PI300. 2. Key on, engine off. 3. Measure the voltage
between:
MAF connector PI14, harness side
Battery
Pin 01
Negative terminal
Is the voltage greater than 10 volts?
-> Yes
INSTALL a new MAF sensor.
Mass Air Flow (MAF) Sensor (18.30.15) CLEAR the DTC. TEST the system for normal operation.
-> No
REPAIR the circuit between the MAF sensor electrical connector, PI14, pin 01 (GU) and BATTERY. This
circuit includes the EMS control relay, fuse 14 of the front power distribution box, and the high
power protection module. For additional information, refer to the wiring diagrams. CLEAR the DTC.
TEST the system for normal operation.
