Signal Too Low - Permanent Fault

ECM-9300 CLUTCH PEDAL POSITION SENSOR, FAULTY SIGNAL
SIGNAL TOO LOW - PERMANENT FAULT

Checking component and wiring



Check clutch pedal sensor resistance between # 2 and # 4, for resistance values see Component specifications. Specifications

Check signal cable between engine control module (ECM) # B15 and clutch pedal sensor # 2 for a short-circuit to ground according to [1][2]Checking Wiring and Terminals. Permanent Fault and an open-circuit according to [1][2]Checking Wiring and Terminals. Permanent Fault

Remedy as necessary.

Other information:
- To connect the breakout box, Connecting the Breakout Box (ECM)
- For information about signals, see Diagnostic Parameters and Pinout Values. Signal Description, ME7, B5XX4T
- With the ignition on and clutch pedal sensor connector disconnected, the voltage between clutch pedal sensor # 2 (engine control module (ECM) side) and ground should be approximately 5 V.


Verification



Hint: After carrying out the repair, check that the fault has been remedied.

- Ignition off.
- Reinstall connectors, components etc.
- Ignition on.
- Read clutch pedal movement by pressing down and releasing clutch pedal.

The value is between 60-70% when the clutch pedal is unaffected and 10-20% when the clutch pedal is fully depressed.

Do the movements correspond?
Yes - Testing Complete.
No - Continue below.


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.
