P2299 — 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.
General code reference. Confirm the definition and diagnostic procedure for your vehicle's year, model and engine. A stored code alone does not identify a failed part.
