Question

it says in the obd2 knock sensor po 325. where is the exact location? does it really need to replace? what could possibly happen to my mini van if i dont?

Answer 1

The sensor is located on top of the engine. You need to removed the intake manifold to access the sensor. If you want optimum performance of your Quest then you need to replaced it. If you don't replace it you may feel some hesitation when taking off from a stop.
