Where is the knock sensor on the engine?
The knock sensor is located on the engine block, cylinder head or intake manifold. This is because its function is to sense vibrations caused by engine knock or detonation. The PCM uses this signal to alter the ignition timing and prevent detonation.
What happens when a shop knock sensor fails?
A failed knock sensor will register a trouble code and illuminate the Check Engine lamp (CEL), although some engines will require multiple failure cycles before storing a code. Knock sensors don’t fail often, but if you suspect this problem, it’s one you need to move on quickly to head off engine damage. SHOP KNOCK SENSORS.
Why do I get less mileage with a bad knock sensor?
If you notice that you’re getting fewer miles per gallon than you normally do, then a bad knock sensor could be contributing to that. Again, there are many reasons for why you might get bad fuel mileage.
What does a ping do to a knock sensor?
If a ping is sensed, it will retard the ignition timing to protect the engine from this damaging pre-ignition. The knock sensor is a piezoelectric sensor that contains a piezoelectric sensing crystal and a resister. This crystal creates a small amount of voltage when shaken.
