DTC P0704: Clutch Pedal Switch: Description

WARNING: This page is about a different car, the 2003 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.

Battery voltage is supplied from the Engine Ignition 1 fuse to the clutch switch. The clutch switch is a normally closed switch. When the clutch pedal is released, the clutch pedal position switch signal circuit is pulled up to battery positive voltage. When the clutch pedal is applied, the switch opens, and the voltage drops to 0 volts. If the Powertrain Control Module (PCM) detects a specified number of vehicle speed transitions without detecting a clutch switch transition, DTC P0704 sets. DTC P0704 is a type "B" DTC.
