Signal Too Low. Intermittent Fault

Checking Cables And Terminals
- Check throttle position (TP) sensor and engine control module (ECM) connectors for loose connections, contact resistance and oxidation.
- Check cable between throttle position sensor terminal 3 and control module # A16 for an intermittent short-circuit to ground.
- Check cable between throttle position (TP) sensor terminal 2 and engine control module # A15 for an intermittent open-circuit and an intermittent short-circuit to ground.

Then proceed to test step 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.
