What it means
The clutch pedal position sensor A reports a circuit/open fault. Pedal position cannot be measured reliably.
At a glance
- Usually lights the check-engine light
How it works
Clutch pedal position sensor A reports pedal movement to the vehicle’s control module so it can coordinate clutch-related functions and, where fitted, gear changes. This code sets when the sensor A circuit is detected as open, leaving the module without a reliable pedal-position signal.
Common causes
Most likely first.
- Position sensor failed
- Wiring fault
- Pin pushed back out of connector body
Symptoms
- Check engine or transmission warning light on
- Harsh, delayed, or missing shifts
- Possible limp mode (locked in one gear)
- Slipping or shuddering during gear changes
How to diagnose it
- Record freeze-frame data and check live clutch pedal sensor A data while slowly pressing and releasing the pedal to see whether the reading is absent or drops out.
- Inspect sensor A’s connector for a loose plug, corrosion, damaged wiring, or a terminal pushed back into the connector body.
- Trace the sensor A wiring using the vehicle diagram and check for an open between the sensor and control module, including at connector terminals.
- Check the sensor circuit’s supply and ground as specified by the manufacturer to distinguish a wiring open from a failed sensor.
- If the circuit reaches the sensor correctly, test sensor A’s output against the manufacturer’s specification through pedal travel.
Common fixes
- Reseat the sensor A connector and secure any loose harness routing.
- Repair an open wire or replace a pushed-back or damaged connector terminal.
- Replace clutch pedal position sensor A if its output is absent despite a sound circuit.
- Clear the code and confirm the sensor reading changes consistently as the pedal moves.
Can I keep driving?
If the pedal signal is unreliable, shifting or clutch-related functions may be affected; avoid driving in traffic if gears are difficult to select. Stop if the vehicle cannot shift predictably, and do not assume the clutch pedal signal will remain available.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
