P0835 Fault Code

Clutch Pedal Switch B Circuit High

• What does that mean?

• Solutions

The P0835 code indicates a problem with the Clutch Pedal Switch B Circuit, specifically that it is reading a high voltage signal. This circuit is essential for detecting when the clutch pedal is depressed, allowing the vehicle's electronic control unit (ECU) to manage various functions like shifting gears and, in some cases, starting the engine. A malfunction in this circuit can hinder vehicle operation and may trigger the check engine light.

What are the symptoms of the P0835 code?

When the P0835 code is triggered, you may experience:

• Difficulty in shifting gears or a grinding sensation when attempting to change gears.
• A check engine light illuminated on the dashboard.
• Potential issues with starting the vehicle, particularly in manual transmissions, as the ECU may think the clutch is not engaged.

What causes the P0835 code?

Several factors can lead to a P0835 code, including:

• A faulty clutch pedal switch that fails to operate correctly.
• Wiring issues, such as shorts or open circuits in the clutch pedal switch circuit.
• Corroded or damaged connectors that disrupt the electrical signal.
• Problems with the vehicle's ECU that affect the interpretation of the switch signals.

How to fix P0835?

To resolve the P0835 code, consider these steps:

• Inspect the clutch pedal switch for proper operation and replace it if faulty.
• Check the wiring and connectors for any signs of damage, shorts, or corrosion, and repair as necessary.
• Use a multimeter to test the switch and circuit inputs to ensure they are within specification.
• Clear the code and perform a test drive to verify the issue has been resolved.
