What P063E means
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.
P063E at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P063E
- Check engine light
- Limp mode, reduced power
- Rough idle, poor throttle response
- Additional throttle circuit codes
Common causes of P063E
- PossibleThrottle sensor or unit not connected, connector or wire open
- PossibleWrong module software or variant for the vehicle (module from another model)
- Less likelyFaulty throttle unit
- Less likelyInternal module fault
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P063E means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 6 | Area: computer (engine control module) and output circuits. |
| 3E | The exact fault in that area. |
What to do next
- Note P063E and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P063E
What does P063E mean?
P063E means "Auto Configuration Throttle Input Not Present Bank 1". Some modules configure themselves at start-up by detecting which inputs are present. It is a generic code, so it means the same on every make.
Is it safe to drive with P063E?
Drive gently and only to a workshop. With P063E the car can go into limp mode (reduced power) to protect itself.
Will P063E fail an emissions test?
Yes, it can. P063E is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P063E to fix?
Difficulty: medium. A typical repair takes 0.5 to 2 hours of work. This is a job for a workshop.
Will P063E clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
