Signal Too Low. Intermittent Fault

Checking Cables and Terminals
- Check that the fresh air intake is intact and properly connected.
- Check cable between main relay (2/32) terminal 3 and mass air flow (MAF) sensor terminal 3 for an intermittent open-circuit.
- Check cable between mass air flow sensor terminal 4 and engine control module (ECM) # A4 for an intermittent open-circuit and an intermittent short-circuit to ground.
- Proceed to: Fault-tracing Information section below.

Fault-tracing Information
For intermittent faults fault-tracing is not followed by a verification because the fault is not present at this moment.

- Do you want to repeat fault-tracing?

Yes:
^ Proceed to: Checking Cables and Terminals section above.

No:
^ Operation done.
