P0704 on Nissan
Clutch Switch Input Circuit Malfunction
P0704 on Nissan vehicles indicates clutch switch input circuit malfunction. Au7o has documented this code across 1 Nissan model — most commonly on 370Z. Applies primarily to manual-transmission vehicles. Set when the PCM detects an implausible or out-of-range signal from the clutch pedal position switch, which informs the PCM whether the clutch is engaged (used for cruise control, starting, and idle/shift logic). Typical repair costs on Nissan range from $10 to $150, depending on the specific model and root cause.
Common Causes of P0704
- •Faulty clutch pedal position switch

- Clutch Pedal Switch / Stopper Pad Deterioration Causing No-Start or Cruise Control Malfunction2021-2022
Owners of late-model 370Zs continue to report failure of the small rubber/plastic stopper pad on the clutch pedal bracket. When it breaks or falls out, the clutch interlock switch may not be depressed, causing a no-crank condition on manual cars; in some cases cruise-control or clutch-switch logic also behaves incorrectly. This is a long-running Z-platform issue and is still documented by owners in the 2021-2022 run.
