P063E Auto Configuration Throttle Input Not Present Bank 1

Some modules configure themselves at start-up by detecting which inputs are present. P063E means the module expects a throttle position input for bank 1 but does not detect it. Unlike circuit codes such as P0122/P0123 or P2135, which judge a present but faulty signal, this says the input was not found for the configuration. No manufacturer document or patent available to us describes this check; the explanation is derived from the J2012 wording. CARB requires input components to be checked for circuit continuity and plausibility, and modules with several variants to detect a wrong one. Possible causes are an unplugged throttle body or open wiring, or software meant for a different vehicle. Without a throttle signal an electronic throttle runs in limp mode.

Likely causes

Throttle sensor or unit not connected, connector or wire open
Wrong module software or variant for the vehicle (module from another model)
Faulty throttle unit
Internal module fault

Symptoms

  • Check engine light
  • Limp mode, reduced power
  • Rough idle, poor throttle response
  • Additional throttle circuit codes
