EGR Throttle Control Circuit High Voltage
The P213D code indicates that the Engine Control Module (ECM) has detected a voltage signal from the Exhaust Gas Recirculation (EGR) throttle control circuit that is higher than the expected range. This circuit controls the EGR throttle plate, which regulates exhaust gas flow into the intake manifold. A high voltage condition can be caused by a short to power, a faulty EGR throttle actuator, or wiring issues. This can lead to improper EGR operation, affecting engine performance and emissions.
1. Most Common Causes
- Short to voltage in the EGR throttle control circuit
- Faulty EGR throttle actuator
- Damaged wiring or connectors
- ECM malfunction (rare)
2. Symptoms You Will Notice
- Check Engine Light illuminated
- Reduced engine power or hesitation
- Rough idle or stalling
- Increased emissions
3. Step-by-Step Diagnosis
Step 1: Use an OBD2 scanner to confirm code P213D and check for other related codes.
Step 2: Visually inspect the EGR throttle actuator wiring and connectors for damage, corrosion, or loose connections.
Step 3: Test the EGR throttle control circuit voltage with a multimeter; compare to manufacturer specifications.
Step 4: If voltage is high, disconnect the actuator and check for short to power; repair as needed.
Step 5: If circuit is okay, replace the EGR throttle actuator and clear the code.
4. Frequently Asked Questions
