Can a car run without a knock sensor
Can a car run without a knock sensor?
Yes, you can drive your vehicle even after its knock sensor fails, but it's not recommended.
A faulty knock sensor can, on some platforms, cause serious driveability issues but a failed knock sensor will usually cause no driveability issues at all - again, depending on the platform/vehicle/engine.
What happens when the knock sensor goes bad?
Reduced engine performance:
A faulty knock sensor may cause the engine to run poorly, with a lack of power and acceleration.
