DTC Code P063E – What does this code mean?

<ul> <li><b>Engine Light ON</b>: The 'Check Engine' or 'Service Engine Soon' warning light illuminates on the dashboard. This is a direct indication of a detected issue with the auto configuration throttle input. Potential causes include a faulty throttle position sensor, wiring issues, or a malfunctioning engine control module (ECM).</li> </ul>

<ul><li>The throttle body may be malfunctioning, leading to improper throttle input signals.</li><li>An open or shorted throttle body harness can disrupt the communication between the throttle body and the engine control module.</li><li>Poor electrical connections in the throttle body circuit can cause intermittent or complete loss of throttle input signals.</li></ul>

<ul> <li><b>Retrieve and Record Codes</b>: Connect a diagnostic scanner to the vehicle's diagnostic port. Retrieve all stored codes and freeze frame data. Record this information for future reference.</li> <li><b>Clear Codes and Test Drive</b>: Clear the codes and test drive the vehicle. Monitor if the code resets or if the PCM enters readiness mode. If the code does not reset, it may be intermittent.</li> <li><b>Check for Other TPS Codes</b>: If there are any other Throttle Position Sensor (TPS) related codes, diagnose and repair those first before addressing the P063E code.</li> <li><b>Consult Technical Service Bulletins (TSB)</b>: Consult your vehicle information source for any applicable TSBs that match the vehicle, symptoms, and codes. This may aid in reaching a correct diagnosis.</li> <li><b>Inspect Throttle Body and Wiring</b>: Visually inspect the throttle body and related wiring for any signs of damage, corrosion, or disconnection. Repair or replace as necessary.</li> <li><b>Test Throttle Position Sensor (TPS)</b>: Using a digital volt/ohmmeter (DVOM), test the TPS for proper voltage and resistance according to the manufacturer's specifications. Replace the TPS if it is found to be faulty.</li> <li><b>Check PCM Connections</b>: Inspect the Powertrain Control Module (PCM) connections for any signs of damage, corrosion, or loose connections. Ensure all connections are secure.</li> <li><b>Re-test and Verify Repair</b>: After performing the necessary repairs, clear the codes and test drive the vehicle again to ensure the P063E code does not reset. Verify that the engine start-up idle quality and drivability are restored.</li></ul>

<p>The DTC code P063E indicates an issue with the auto configuration throttle input not being present. This is a critical issue as it can affect the vehicle's throttle control, leading to potential loss of power or erratic engine behavior.</p><ul><li><b>Immediate Actions:</b> Inspect the throttle position sensor and related wiring for faults.</li><li>Check the ECM (Engine Control Module) for any software updates or faults.</li><li>Address any detected issues promptly to avoid further engine performance problems.</li></ul>
