Exhaust Gas Recirculation Control Circuit Range/Performance Problem (Bank 2)
There’s an issue with the EGR control circuit on bank 2.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The computer is getting weird readings from the EGR system for bank 2, which helps reduce emissions by recirculating exhaust back into the engine for combustion.
What the computer is actually seeing
The Engine Control Module (ECM) monitors the EGR valve position and the readings should correlate to the expected values when the EGR is activated. If the readings are out of range (e.g., 0.2V to 4.7V for EGR position sensor), the code sets.
What a healthy reading looks like
EGR position sensor voltage should range from 0.2V (closed) to 4.7V (fully open).
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Inspect EGR valve and connectors for physical damage or corrosion. Is there any visible damage? If yes, repair or replace the affected parts.
- 22. Check EGR position sensor voltage with a multimeter while the engine is running. Is it between 0.2V to 4.7V? If no, the sensor or wiring may be faulty.
- 33. Test the EGR valve operation. Apply power to the EGR valve. Does it open and close properly? If no, replace the EGR valve.
- 44. Clear the code and take the vehicle for a test drive. Does the code return? If yes, further diagnose the wiring and connectors to the EGR system.
Common causes
- Faulty EGR valve
- EGR position sensor issue
- Wiring or connector problems
- Vacuum leak in EGR system
- Clogged EGR passages

Frequently asked questions
Is it safe to drive with this code?
It's generally safe to drive, but expect reduced performance and increased emissions.
Will this code come back after clearing it?
It can come back if the underlying issue isn't fixed.
Why does this code show up with other EGR codes?
Multiple codes can indicate a systemic issue with the EGR system or related components.
