Drive with caution — fix soon.
This code means the engine computer is seeing too high a voltage signal from the 'A' EGR position sensor, which tracks how the exhaust gas recirculation valve is moving. It usually points to a wiring problem, a bad sensor, or a faulty EGR valve. It's a fairly common code and is often fixable without major engine work.
$150 – $450
Varies by vehicle and root cause.
For short trips, usually yes, since it's mostly an emissions and sensor problem and won't typically leave you stuck. Still, you shouldn't rely on it long-term, as a faulty EGR system can hurt fuel economy and cause it to fail emissions testing. Get it diagnosed soon.
Most repairs land between about $150 and $450. If it's just wiring or a connector, it's on the lower end; replacing the EGR position sensor or the valve itself pushes it higher.
It's not an emergency and rarely leaves you stranded, but it shouldn't be ignored. Left alone it can worsen fuel economy, affect performance, and cause a failed emissions test.
It means the EGR position sensor 'A' is sending a voltage signal that's higher than expected, which usually points to a wiring short to voltage, a bad sensor, or a faulty connector rather than the engine itself being damaged.
