Checking cables and connectors
Check signal cable between engine control module (ECM) #A22 (#A22) and mass air flow (MAF) sensor #5 for an intermittent short-circuit to supply voltage according to Short-circuit to supply voltage, intermittent faults .
Check power supply cable between engine control module (ECM) #A58 (#A58) and mass air flow (MAF) sensor #3 for an intermittent open-circuit according to Open-circuit, intermittent faults

- Connecting the breakout box/accessing the control module, see Connecting the breakout box .
- To access/replace the Mass Air Flow (MAF) sensor, see Mass air flow sensor (MAF), replacing .
- With the ignition on and mass air flow (MAF) sensor connector connected the voltage at mass air flow (MAF) sensor #2 should be approximately Ubat , mass air flow (MAF) sensor #3 should be ground and mass air flow (MAF) sensor #5 should be approximately 1 volt.
