The P213A: Exhaust Gas Recirculation (EGR) Throttle Control Circuit ‘B’ /Open refers to an open circuit issue in the EGR throttle control system, specifically in circuit ‘B’. This can result from faulty EGR throttle control, wiring problems, or an open circuit, potentially affecting engine performance and emissions control.
P213A – Quick Overview
| Code | Information |
|---|---|
| Meaning | P213A: Exhaust Gas Recirculation Throttle Control Circuit ‘B’ /Open |
| Is it serious? | Yes, it can lead to improper EGR operation and cause drivability or emissions issues. |
| Possible causes | – Open circuit in the exhaust gas recirculation (EGR) throttle control ‘B’ – Faulty EGR throttle control – Wiring issues |
| How to diagnose? | – Inspect wiring and connectors for the EGR throttle control ‘B’ – Test the EGR throttle control for faults – Check for open circuits |
P213A Meaning
The P213A code indicates that there is an open circuit in the EGR throttle control circuit ‘B’. The EGR throttle control is responsible for regulating the flow of exhaust gases back into the engine to reduce emissions. An open circuit could lead to the EGR system malfunctioning, causing poor engine performance and increased emissions.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for any related codes that might provide further context for the issue. | OBD-II Scanner |
| Inspect EGR Throttle Control Wiring | Visually inspect the wiring and connectors leading to the EGR throttle control ‘B’ for signs of damage, loose connections, or corrosion. | Flashlight, Multimeter |
| Check for Open Circuits | Use a multimeter to check for continuity in the EGR throttle control circuit ‘B’. Identify any open circuits and repair them. | Multimeter, Wiring Diagram |
| Test EGR Throttle Control for Faults | Use a diagnostic tool to test the functionality of the EGR throttle control. If the control is faulty, it may need to be replaced. | Diagnostic Tool |
| Inspect and Clean Connectors | Ensure that all connectors are clean, properly connected, and free of corrosion. Clean or replace them if necessary. | Contact Cleaner, Flashlight |
| 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 P213A code has not returned. | OBD-II Scanner |
