The P213D: Exhaust Gas Recirculation (EGR) Throttle Control Circuit ‘B’ High indicates that the voltage in the EGR throttle control circuit ‘B’ is higher than expected. This could be caused by a faulty EGR throttle control, wiring issues, or an electrical fault affecting the EGR system’s performance.
P213D – Quick Overview
| Code | Information |
|---|---|
| Meaning | P213D: Exhaust Gas Recirculation Throttle Control Circuit ‘B’ High |
| Is it serious? | Yes, it can cause improper EGR operation, leading to performance issues and increased emissions. |
| Possible causes | – High voltage in the EGR throttle control circuit ‘B’ – Faulty EGR throttle control – Wiring issues |
| How to diagnose? | – Measure voltage in the EGR throttle control circuit ‘B’ – Test the EGR throttle control – Inspect wiring and connections |
P213D Meaning
The P213D code indicates that the EGR throttle control circuit ‘B’ is experiencing high voltage, which can affect the proper operation of the exhaust gas recirculation system. This may lead to increased emissions, poor engine performance, and drivability problems. Common causes include faulty wiring or a malfunctioning EGR throttle control.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for other related codes that might provide additional insight into the EGR system’s health. | OBD-II Scanner |
| Measure Voltage in the Circuit | Use a multimeter to measure the voltage in the EGR throttle control circuit ‘B’. Compare the readings with manufacturer specifications to determine if the voltage is too high. | Multimeter |
| Test the EGR Throttle Control | Use a diagnostic tool to test the EGR throttle control for proper operation. Verify that it operates within the expected voltage range and replace it if necessary. | Diagnostic Tool |
| Inspect Wiring and Connections | Visually inspect the wiring and connectors leading to the EGR throttle control ‘B’ for signs of damage, loose connections, or corrosion. Repair or replace as necessary. | Flashlight, Multimeter |
| Check for Shorts or Open Circuits | Perform continuity tests on the wiring to ensure there are no shorts or open circuits that could cause high voltage. | Multimeter, Wiring Diagram |
| Clear the Code and Test Drive | After making the necessary repairs, clear the code using an OBD-II scanner and take the vehicle for a test drive to confirm the issue is resolved. | OBD-II Scanner |
| Recheck for Codes | After the test drive, re-scan the vehicle to ensure the P213D code has not returned. | OBD-II Scanner |
