What Does P213A Mean?
The PCM detects an open circuit in the EGR throttle control circuit B. This indicates a break in the electrical pathway to the EGR throttle valve actuator, preventing proper exhaust gas recirculation system operation.
Common Causes
35%
Open circuit or broken wire in EGR throttle valve actuator wiring harness
30%
Failed EGR throttle valve actuator motor or position sensor
20%
Corroded or disconnected electrical connector at EGR throttle valve
10%
Blown fuse or failed relay supplying power to EGR throttle circuit
5%
PCM internal driver circuit failure for EGR throttle control
Diagnostic Steps
1
Step 1: Locate EGR throttle valve and inspect electrical connector for corrosion, damage, or loose connection; secure and clean as needed
2
Step 2: Check relevant fuses and relays for EGR system using wiring diagram; test and replace if blown
3
Step 3: With connector disconnected, measure resistance of EGR throttle actuator motor (typically 5-50 ohms); verify against manufacturer specifications
4
Step 4: Check for battery voltage at actuator connector on power supply circuit with key on; trace open circuit if voltage is absent
5
Step 5: Test PCM control circuit with multimeter or oscilloscope to verify PCM is sending proper command signal to actuator
Estimated Repair Cost
$200 - $900
Parts + labor, varies by vehicle and location
The PCM detects an open circuit in the EGR throttle control circuit B. This indicates a break in the electrical pathway to the EGR throttle valve actuator, preventing proper exhaust gas recirculation system operation.
The most common cause of P213A (Exhaust Gas Recirculation Throttle Control Circuit "B" /Open) is: Open circuit or broken wire in EGR throttle valve actuator wiring harness
Typical repair costs for P213A range from $200 to $900, depending on the vehicle, location, and whether you do it yourself or go to a shop.
No immediate safety concerns for driving. May experience reduced fuel economy, increased emissions, and potential engine performance issues. Repair within reasonable timeframe to prevent catalytic converter damage.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P213A to identify the root cause.
