Causes
- Missing or open circuit in throttle position (TPS) or accelerator pedal position (APP) wiring
- Disconnected, corroded, or damaged connector at throttle body, pedal module, or PCM
- Failed throttle body, TPS, or accelerator pedal sensor
- Blown fuse, poor power or ground to the sensor or PCM
- PCM software/calibration missing, corrupted, or not programmed
- CAN bus or communication fault preventing configuration data exchange
Symptoms
- Check Engine Light (MIL) illuminated
- Throttle response reduced or vehicle in limp/limitation mode
- Poor or inconsistent idle and throttle control
- Stored code P063E (Auto Configuration Throttle Input Not Present Bank 1)
- Possible lack of driveability or sudden throttle cutout
What to check
- Scan for stored codes and freeze frame data; note any related DTCs (TPS, APP, CAN, PCM)
- Visually inspect connectors and wiring at the throttle body, pedal module, and PCM for damage or corrosion
- Verify battery voltage and fuses for the throttle/PCM circuits
- Use scan tool to view live TPS and APP sensor values and compare to expected at closed and open throttle
- Check for CAN bus communication faults and module availability
- Attempt PCM auto-configuration or relearn procedure if available and monitor result
Signal parameters
- Throttle position sensor voltage: typically ~0.2–0.8 V at closed throttle and ~4.0–4.8 V at wide-open (manufacturer-specific)
- Accelerator pedal position sensor voltages (two sensors) correlation and inverse/expected values
- Reference supply voltage to sensors: typically 5.0 V
- Sensor ground continuity
- CAN bus module presence and message counts (if applicable)
Diagnostic algorithm
- Read and record all stored DTCs and freeze frame data. Note if other throttle/pedal or CAN-related codes are present.
- With key on engine off, visually inspect connectors at the throttle body, accelerator pedal module, and PCM. Repair any corrosion, bent pins, or loose connectors.
- Check fuses and battery voltage. Confirm proper power and ground at the throttle body and pedal sensor circuits using a DVOM.
- Use a scan tool to observe live TPS and APP sensor data. Verify sensor voltages and percent values change smoothly with pedal and throttle movement.
- Perform continuity and resistance checks on wiring between sensors and PCM. Look for opens, shorts to power/ground, and intermittent faults (wiggle test while observing live data).
- Check CAN bus health and ensure all required modules are communicating. Address any bus fault codes.
- If wiring and sensors test good, follow manufacturer procedure to perform auto-configuration/relearn for the throttle system. Clear codes and re-test.
- If the code returns and sensor/ wiring checks fail to identify a fault, consider replacing the throttle body or pedal module (swap test if possible) before replacing PCM.
- Only replace or reflash the PCM after confirming all external components, wiring, and communication are verified good and after checking for updated software/calibrations from the manufacturer.
Likely causes
- Loose/disconnected connector at throttle body or pedal position sensor
- Faulty throttle body assembly or pedal position sensor
- Damaged wiring harness (open/short) between sensor and PCM
- PCM not loaded with correct calibration or requiring reflash
Fault status
Status
PCM did not detect the expected auto-configuration throttle input for Bank 1. Throttle/pedal sensor signal or configuration data is missing or out of specification. Further diagnostic testing of sensors, wiring, and PCM configuration is required.
Repair difficulty: Medium
Diagnostic time: 0.5-2.0 hours
