The code indicates a fault in the circuit that detects whether the clutch pedal is fully depressed before allowing the transmission to engage gear. This safety circuit prevents the vehicle from starting or shifting when the clutch is not engaged.
The switch itself can fail open or short, preventing the required signal from reaching the PCM.
Damaged insulation, chafed wires, or a short to ground can interrupt the signal.
Oxidation or poor contact increases resistance and can cause intermittent failures.
A fuse protecting the circuit may have opened, cutting power to the switch or PCM.
A PCM input failure is possible but extremely rare; it usually only occurs after extensive electrical damage.
No. The PCM is rarely the cause; most failures are due to a bad switch, wiring, or connector.
Driving may be limited or impossible because the transmission can be locked out until the circuit is repaired.
Yes; checking and replacing a blown fuse is a quick first step that often resolves the issue.
The clutch interlock safety switch is a simple contact switch, not a sensor; it should be tested and replaced only if found faulty.
