Drivable short-term, but fix now to avoid damage.
This code means the engine control module ran an internal memory check and the result didn't match what it expected, indicating a memory error. It's usually caused by a fault inside the module itself, though corrupted programming, voltage problems, or poor connections can contribute. It's a serious code that often requires reprogramming or replacing the module.
$200 – $1200
Varies by vehicle and root cause.
Only with caution. The engine may run poorly or drop into limp mode, so a short trip might be okay, but get it diagnosed before relying on the vehicle.
Costs range from about $200 for reprogramming up to $1,200 or more if the engine control module needs to be replaced and programmed.
Yes. It points to an internal module memory error that can affect engine operation and trigger other faults, so it shouldn't be ignored.
Sometimes. Reprogramming the module or fixing a voltage or connection issue can clear it, but a confirmed internal memory failure usually requires module replacement.
