Re: Replacing Knock Sensor
The knock sensor is located under the hood, near the front and center part of the engine; under the intake manifold. The intake manifold must have to be moved in order to gain access to the knock sensor. Thus, the high labor cost.
In all honesty, every EVERY 95-98 Nissan Maxima that I've diagnosed and worked on has at least the code 0304 which triggers the check engine symbol; the knock sensor code.
Just diagnosed one today that keeps cutting off, but that's being caused by the MASS AIR FLOW sensor; code 0102.
These Maximas are NOTORIOUS for the knock sensor code, though. Maybe there's a recall campaign somewhere and we can make the dealer fix it for free! Hmm.. Checking..
MASS AIR FLOW sensor: $208(adv)-$488(dealer)
KNOCK SENSOR:$130(advauto)-$150(dealer)
