Clutch Pedal Switch Circuit High
The P0835 code indicates that the Powertrain Control Module (PCM) has detected a high voltage condition in the clutch pedal switch circuit. This switch signals the PCM when the clutch is engaged or disengaged, and a high voltage reading suggests a short to power, a faulty switch, or a wiring issue. This can affect starting, cruise control, and engine management.
01. Most Common Causes
- Faulty clutch pedal switch
- Short to power in the switch circuit
- Damaged wiring or connector
- Corroded terminals
- Failed PCM (rare)
02. Symptoms You Will Notice
- Engine may not start unless clutch is pressed
- Cruise control inoperative
- Check Engine Light illuminated
- Stalling when clutch is released
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Visually inspect clutch pedal switch and wiring for damage or corrosion.
Step 3: Test switch operation with a multimeter; check for voltage and continuity.
Step 4: Check for short to power by disconnecting switch and testing circuit voltage.
Step 5: If switch and wiring are good, test PCM input/output signals.
