Can drive — fix at your convenience.
This code means the engine is detecting more exhaust gas recirculation (EGR) flow than it should, often because an EGR valve is stuck open or the system is leaking exhaust into the intake. Common fixes include cleaning or replacing the EGR valve, clearing carbon from the passages, or repairing a stuck position sensor. It's an emissions-related code and is usually a straightforward repair.
$150 – $500
Varies by vehicle and root cause.
Yes, you can usually drive normally for a while since this is an emissions issue. You may notice a rough idle or occasional stalling at stops. Have it repaired within a week or two to protect fuel economy and pass emissions testing.
Repairs typically run $150 to $500. Cleaning the EGR valve and passages is the cheaper option, while a full EGR valve replacement with labor reaches the higher end.
It's a low-severity, emissions-related code, so it's not an immediate danger. However, the rough idle and stalling can be annoying and it will fail a smog check, so it's worth fixing soon.
Most often the EGR valve is stuck open, frequently from carbon buildup, letting too much exhaust into the intake. A leaking gasket or a faulty position sensor reporting the wrong flow can also trigger it.
