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.

Bank 1 is the side of the engine with cylinder 1. Inline engines only have this bank.

Symptoms

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

Most 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

What to check, in order

Start with the simplest. You can tick off each step.

1. Check the pedal and throttle connectors
2. Use live data to confirm that both sensors rise smoothly and consistently
3. Clean the throttle if it has carbon buildup
4. Run the relearn procedure with the scanner if the manufacturer requires it
5. Replace the part identified by the diagnosis

Good to know

• Repair difficulty: medium
• It can trigger limp mode.
• It affects emissions.

What each character of P063E means

• P: Powertrain: engine and transmission
• 0: Generic code: same on every make
• 6: Control modules and outputs
• 3E: Specific fault in that system

Frequently asked questions

Can I keep driving with code P063E?

Be careful: the car may suddenly lose power. If it goes into limp mode, get off the highway and calmly make your way to a repair shop.

What causes code P063E?

The most common causes are: 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.
