What Does P063E Mean?
The PCM/ECM has detected that the throttle input signal is not present during the auto-configuration process. When the PCM powers up, it performs a self-check to verify all required sensor inputs are available. This code indicates the throttle position or accelerator pedal position signal was missing during this initialization. The driver may experience a no-start condition, reduced power mode, or erratic throttle response.
Safety Warning
Without a valid throttle input, the engine may not start or may operate in a severely limited reduced power mode. If the vehicle does run, throttle response may be unpredictable. Do not drive the vehicle until the issue is diagnosed and resolved, as loss of throttle control is a serious safety concern.
Common Causes
35%
Disconnected or damaged throttle position sensor or accelerator pedal position sensor connector
25%
Open circuit in the throttle position signal wiring
20%
Faulty throttle position sensor or accelerator pedal position sensor
12%
PCM/ECM not providing 5V reference to the sensor
8%
PCM/ECM internal fault in auto-configuration routine
Diagnostic Steps
1
Check the TPS and APP sensor connectors for proper seating, corrosion, or damage. Disconnect and reconnect each connector firmly, then clear the code and cycle the ignition to trigger auto-configuration.
2
Measure the 5V reference voltage at the TPS connector — should be 4.9–5.1V between the reference and ground pins. If missing, check the 5V reference circuit back to the PCM.
3
With the ignition on, monitor TPS voltage — should read approximately 0.4–0.8V at closed throttle. Monitor APP voltage — should read approximately 0.5–1.0V with foot off the pedal.
4
Check continuity of the TPS signal wire from the sensor connector to the PCM connector. Also check for shorts to ground or power.
5
If all wiring and sensors check out, attempt a PCM reflash. If the code persists, the PCM's auto-configuration module may be faulty.

The most common cause of P063E (Auto Configuration Throttle Input Not Present) is: Disconnected or damaged throttle position sensor or accelerator pedal position sensor connector
Typical repair costs for P063E range from $50 to $600, depending on the vehicle, location, and whether you do it yourself or go to a shop.
