Signal Too Low

Signal too low

Checking the throttle position (TP) sensor signal




- Ignition on.
- Go into scrolling values.
Read off the position of the throttle position (TP) sensor.
The reading should be approximately 0 % with the accelerator pedal (AP) up.
The value should be approximately 100 % with the accelerator pedal (AP) fully depressed.





Is the correct value displayed?

Yes - Intermittent fault

No - Checking for a short-circuit

-------------------------------------------------

Checking for a short-circuit
Check the cable between automatic transmission control module (TCM) terminal 38 and engine control module (ECM) terminal 41 for a short-circuit to ground according to Checking wiring and terminals. Permanent fault Checking Wiring And Terminals. Permanent Fault.
In cars equipped with the DSA anti-spin system, check the circuit for DSA control module terminal 5 for a short-circuit to ground according to Checking wiring and terminals. Permanent fault Checking Wiring And Terminals. Permanent Fault.

Verification

Hint: After repairs have been completed they must be verified as follows to ensure that the fault has been eliminated:








- Ignition off.
- Reconnect the connectors, reinstall components etc.
- Ignition on.
- Go into scrolling values.
Read off the position of the throttle position (TP) sensor.
The reading should be approximately 0 % with the accelerator pedal (AP) up. The value should be approximately 100 % with the accelerator pedal (AP) fully depressed.





Are the correct values displayed?

Yes - VERIFIED

No - VERIFICATION FAILED

Information

Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.

Do you want to exit fault-tracing?

Yes - Exit fault-tracing

No - Attempt New Test

Fault-tracing information
If the fault is intermittent, do not verify fault-tracing if the fault does not recur.
It is possible to view the information again, or leave fault-tracing for this diagnostic trouble code (DTC).
