What it means

P063E is a generic code meaning the engine control unit's automatic configuration routine expected a throttle-related input and did not detect it. The wording 'Bank 1' suggests it relates to the first engine bank or the primary throttle circuit. The exact input checked and the strategy used vary by manufacturer and engine, so check the vehicle-specific data.

Symptoms

  • Engine warning light on
  • Reduced power or limp-home mode
  • Poor or delayed throttle response
  • Unstable or raised idle
  • Engine may not start, or stalls after starting
  • Other throttle or pedal codes stored alongside

Possible causes

  • Wiring fault or poor connection in the throttle body or throttle position sensor circuit (open circuit, chafing, corroded or loose pins)likely
  • Faulty throttle body or internal position sensor not sending a signallikely
  • Accelerator pedal sensor fault or pedal circuit faultpossible
  • Sensor supply or reference voltage or ground fault affecting the throttle inputpossible
  • Throttle body not relearned or configured after replacement or battery disconnectionpossible
  • Internal engine control unit fault or outdated softwarerare

How to diagnose

  1. Read all stored and pending codes and freeze frame data, noting any other throttle, pedal or sensor supply codes.
  2. Visually inspect the throttle body connector, wiring loom and earths for damage, water ingress, corrosion or rubbing.
  3. Check the battery condition and charging voltage, as low voltage can upset configuration routines.
  4. With live data, compare throttle position and accelerator pedal readings with the pedal at rest and fully pressed, and look for missing or frozen values.
  5. Check the sensor reference voltage, signal and ground at the throttle body connector against the manufacturer's specification.
  6. Test the wiring for continuity and shorts between the connector and the control unit, with the battery disconnected as appropriate.
  7. Check for recent work such as throttle body replacement, cleaning or battery disconnection, and whether a relearn was done.
  8. Check for relevant manufacturer software updates or bulletins for the model and engine.

How to fix

  • Repair or replace damaged wiring, terminals or connectors in the throttle circuit.
  • Replace the throttle body if its sensor or motor is proven faulty.
  • Replace the accelerator pedal assembly if its sensor readings are faulty.
  • Correct any supply voltage or ground fault found, then clear the codes.
  • Carry out the throttle adaptation or relearn procedure specified for the vehicle.
  • Update the control unit software if a fault in the existing calibration is confirmed as the cause.

Can I keep driving?

Medium severity

The car may enter limp-home mode with reduced power, which can be unsafe when overtaking or pulling out of junctions. Limit driving to getting it to a workshop soon, and stop if the engine stalls or throttle response becomes unpredictable.
