Knock sensorThe knock sensor for a 1996 Nissan Altima is located on the backside of the block above the oil filter.But before you go and change it out, run a tank of the best/hightest rated gas you can find and see if that fixes the problem. On my 1995 the Knock sensor is located under the plenum and intake manifold on top of the middle of the block.
It is located on the back of the engine block just above the oil filter
It is located unter the intake manifold near the oil filter.
It is located on the back (firewall) side of the engine block beneath the intake manifold. It's a real pain to get to.
The knock sensor is located under the intake manifold on the passenger side of the engine. It can be accessed from under the vehicle. Look above and to the slight left of the oil filter on the back of the engine. The knock sensor will resemble a small battery terminal with a bolt through to the engine.
