EGR Throttle Control Circuit Open
The P213A code indicates an open circuit in the exhaust gas recirculation (EGR) throttle control circuit. This means the engine control module (ECM) has detected a loss of continuity or high resistance in the wiring or connector of the EGR throttle actuator, which controls the flow of exhaust gases back into the intake. An open circuit prevents the actuator from operating correctly, leading to improper EGR flow and potential drivability issues.
01. Most Common Causes
- Open or shorted wiring in the EGR throttle control circuit
- Corroded or damaged connector at the EGR throttle actuator
- Failed EGR throttle actuator (motor or position sensor)
- Faulty engine control module (rare)
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Rough idle or engine stalling
- Reduced engine power or hesitation during acceleration
- Increased exhaust emissions
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data. Clear codes and test drive to see if P213A returns.
Step 2: Visually inspect the EGR throttle actuator connector and wiring for damage, corrosion, or loose pins.
Step 3: Using a multimeter, check for continuity and proper voltage (typically 5V reference, ground, and signal) at the actuator connector with key on.
Step 4: If wiring is intact, test the actuator by applying battery voltage directly (if safe) or using a scan tool to command the throttle. Replace actuator if no response.
Step 5: If all checks pass, suspect a faulty ECM and perform further diagnostics or reprogramming.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances with P213A, as it can cause poor engine performance, stalling, and increased emissions. You may be able to drive to a repair shop, but avoid heavy acceleration or towing.
How much does it cost to fix?▼
The cost to fix P213A typically ranges from $150 to $400, including parts and labor. The EGR throttle actuator itself costs $100-$250, plus diagnostic time and labor.
