Meaning | P213B: Exhaust Gas Recirculation Throttle Control Circuit ‘B’ Range/Performance |
Is it serious? | Yes, it can lead to poor engine performance, increased emissions, or drivability problems. |
Possible causes | – EGR throttle control ‘B’ out of range or performance issues – Faulty EGR throttle control – Control module or wiring issues |
How to diagnose? | – Test the EGR throttle control ‘B’ for proper range and performance – Inspect control module functionality – Check wiring and connections |
P213B Meaning
The P213B code indicates that the EGR throttle control ‘B’ is not functioning within its expected range, which can lead to poor exhaust gas recirculation and increased emissions. This may be caused by an internal fault in the EGR throttle control, control module issues, or wiring problems affecting performance.
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 may provide additional context or indicate broader EGR system problems. | OBD-II Scanner |
Inspect EGR Throttle Control Wiring | Visually inspect the wiring and connectors for EGR throttle control ‘B’ to ensure there are no signs of damage, loose connections, or corrosion. | Flashlight, Multimeter |
Test EGR Throttle Control for Range and Performance | Use a diagnostic tool to test the EGR throttle control ‘B’ and verify that its output is within the manufacturer’s specifications for proper range and performance. Replace if necessary. | Diagnostic Tool, Multimeter |
Check Control Module Functionality | Test the control module that communicates with the EGR throttle control to ensure it is functioning properly and sending correct signals. | Diagnostic Tool |
Inspect and Repair Wiring Issues | Use a multimeter to check for shorts, open circuits, or damaged wiring in the circuit between the EGR throttle control and the control module. Repair any faulty wiring. | Multimeter, Wiring Diagram |
Clear the Code and Test Drive | After making necessary repairs or adjustments, clear the code with 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 P213B code has not returned. | OBD-II Scanner |
