Can drive — fix at your convenience.
This code means the engine computer is seeing low voltage from the 'A' EGR position sensor circuit, which it uses to know how far the EGR valve is open. It's often caused by a wiring short to ground, a bad connector, or a failing position sensor inside the EGR valve. Repairs usually involve fixing the wiring or replacing the sensor or EGR valve assembly, and it's typically an affordable fix.
$150 – $450
Varies by vehicle and root cause.
Yes, in most cases you can drive normally since this is an emissions sensor issue. You might notice a rough idle or minor hesitation. Get it repaired soon to keep emissions in check and pass a smog test.
Most repairs run $150 to $450. A wiring or connector fix is the cheaper end, while replacing the EGR position sensor or the EGR valve assembly with labor lands higher.
It's low severity. The car usually drives normally, but the EGR system can't be controlled accurately without a good position signal, which affects emissions. It's worth fixing but not an emergency.
It means the EGR position sensor is sending lower voltage than the computer expects, often signaling a short to ground or a failed sensor. The computer then can't tell the valve's true position, so it sets this code.
