Can drive — fix at your convenience.
This code means the EGR valve's actual position or flow doesn't match what the engine computer commanded, so it's out of its expected range or responding too slowly. It's frequently caused by carbon buildup sticking the valve, a faulty position sensor, or a worn EGR valve. Cleaning the valve and passages often fixes it, though sometimes the EGR valve needs replacing.
$150 – $500
Varies by vehicle and root cause.
Yes, you can usually drive normally for a while since it's an emissions issue. You may feel a rough idle or slight hesitation. Have it repaired within a week or two to prevent carbon buildup and an emissions failure.
Repairs generally run $150 to $500. Cleaning the EGR valve and passages is the budget option, while replacing the EGR valve with labor is at the higher end of that range.
It's low severity. The engine usually runs fine, but the EGR system isn't performing correctly, which hurts emissions and economy. It's worth fixing soon but isn't an emergency.
It means the EGR valve is opening or closing, but not by the right amount or quickly enough to match the computer's command. This is often due to carbon sticking the valve or a position sensor reading incorrectly.
