Brake Pedal Position / Accelerator Pedal Position Correlation
The ECU detects simultaneous brake and accelerator activation beyond a permitted threshold. Modern brake-throttle override safety logic forces idle in this state — usually triggered by a stuck brake light switch or a faulty pedal sensor.
Affected components
- Brake light switch
- Accelerator pedal sensor
Common causes
- High likelihood: Brake light switch stuck on
- Medium likelihood: Accelerator pedal sensor drift
Diagnostic notes
- The malfunction indicator lamp may illuminate
- Reduced-power or limp mode may occur
