1. DTC P0808 description
The clutch pedal stroke sensor is installed to the clutch master cylinder. The ECM detects the clutch pedal stroke amount based on the signal from the clutch pedal stroke sensor. The clutch pedal stroke sensor signal voltage increases as the clutch pedal is depressed. The sensor has the following circuits.
- 5 V reference circuit
- Low reference circuit
- Clutch pedal stroke sensor signal circuit
The clutch pedal stroke sensor sends signals related to the pressure changes in the clutch master cylinder to the ECM via the signal circuit. If the ECM detects an excessively high signal voltage, the DTC is set.
