OBD-II (EN): Clutch Pedal Position Switch Circuit Malfunction
Code P1805 indicates an irregularity in the clutch pedal position switch circuit – a typical fault in Nissan and Infiniti models. The cause may be a worn switch, mechanical play in the pedal assembly, or a control module adaptation issue. We recommend diagnosis at a workshop with a dedicated scanner for Nissan/Infiniti vehicles.
Symptoms
Incorrect idle speed (too high or fluctuating), possible cruise control issues, occasional jerking or engine stalling when pressing the clutch, MIL (check engine light) on the dashboard.
Possible causes
• Worn or damaged clutch pedal switch (mechanically worn) • Mechanical play on the pedal pivot or bent switch mounting bracket • Dirt or corrosion on switch contacts causing improper closure • Incorrect idle adaptation after sensor/switch replacement (missing initialization procedure) • Outdated or faulty ECM firmware (engine control module)
