DTC P0704: Clutch Pedal Switch: Description

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2002 GMC Sonoma, 2002 GMC Safari, 2002 GMC Jimmy, 2002 Chevrolet S10 Pickup, and 2002 Chevrolet Blazer. However, it is still accessible from the selected car via links, so may be relevant.

Battery voltage is supplied from the ABS 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 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 will set.
