Auto Configuration Throttle Input Not Present
The P063E code indicates that the Engine Control Module (ECM) has detected a missing or invalid throttle input signal during the automatic throttle configuration process. This typically occurs when the ECM attempts to learn the throttle position sensor (TPS) range and fails to receive a valid signal, often due to wiring issues, a faulty TPS, or a malfunctioning throttle actuator control (TAC) module.
01. Most Common Causes
- Faulty throttle position sensor (TPS)
- Open or short circuit in TPS wiring
- Malfunctioning throttle actuator control (TAC) module
- Corroded or loose electrical connectors
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Reduced engine power or limp mode
- Poor throttle response or hesitation
- Engine stalling or rough idle
03. Step-by-Step Diagnosis
Step 1: Scan for additional codes and freeze frame data.
Step 2: Inspect TPS wiring and connectors for damage or corrosion.
Step 3: Test TPS voltage and resistance with a multimeter.
Step 4: Check TAC module communication and power/ground circuits.
Step 5: Perform throttle body relearn procedure if wiring is okay.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
No, it is not safe. The vehicle may enter limp mode, reducing power and increasing the risk of accidents. Have it diagnosed immediately.
How much does it cost to fix?▼
Typical repair costs range from $50 to $150 for diagnosis and minor repairs like connector cleaning, but could be higher if the TPS or TAC module needs replacement.
