(J623) electrical harness connector T121 terminals for an open circuit.
Specified value: 1.5 ohms max.
If the specification was not obtained:
Check the wiring for a short circuit to each other, Battery (+), and Ground (GND).
Check the electrical harness connector for damage, corrosion, lose or broken terminals.
If necessary, repair the faulty wiring connection.
If no malfunction is detected in the wiring and if the voltage supply was OK:
Replace Mass Air Flow (MAF) Sensor (G70).
After repair work, the following work steps must be performed in the following sequence:
1. Check the DTC memory. Refer to => [ Diagnostic Mode 03 - Read DTC Memory ] See: Computers and Control Systems/Testing and
Inspection/Scan Tool Testing and Procedures/Diagnostic Modes 01 - 09 [ (BPY) (BUB) ]/Diagnostic Mode 03 - Read DTC Memory.
2. If necessary, erase the DTC memory. Refer to => [ Diagnostic Mode 04 - Erase DTC Memory ] See: Computers and Control Systems/Testing and
Inspection/Scan Tool Testing and Procedures/Diagnostic Modes 01 - 09 [ (BPY) (BUB) ]/Diagnostic Mode 04 - Erase DTC Memory.
3. If the DTC memory was erased, generate readiness code. Refer to => [ Readiness Code ] See: Computers and Control Systems/Testing and
Inspection/Monitors, Trips, Drive Cycles and Readiness Codes.
