Drive with caution — fix soon.
This code means the voltage from the knock sensor is reading higher than expected. It usually points to a short to power in the wiring, a failed knock sensor, or a connector issue. The fix typically involves inspecting the wiring for shorts to voltage and replacing the knock sensor if needed.
$150 – $500
Varies by vehicle and root cause.
Usually yes, for short distances. The engine runs, but its detonation protection may be compromised. Drive gently and have it checked within a week.
Most repairs are $150 to $500. The sensor is typically inexpensive, but labor rises when it's mounted under the intake manifold.
It's moderate. There's no immediate breakdown, but a malfunctioning knock sensor reduces the engine's protection from damaging detonation.
It means the sensor's voltage signal is reading higher than normal. This often points to a short to power in the wiring or a failing sensor.
