LS does not have a knock sensor. GSR does have a knock sensor
The knock sensor detects spark knock or ping.
That will cause you to fail an emissions inspection. Anything which triggers the CEL will, because everything which triggers it will adversely impact the emissions system on that vehicle.
Where is the knock sensor for a 99 pathfinder
that the knock sensor does
Yes. Any faulty emissions control sensor, including knock sensors, will result in an automatic fail of any emissions control test, period. It doesn't even matter if your vehicle's actual exhaust emissions are within acceptable limits. In most cases, once it is determined that a sensor is bad, the test is ended immediately, and considered failed.
you mean knock sensor
knock sensor location
I don't believe it has a knock sensor.
Knock sensor = CKP sensor on this vehicle.
The knock sensor retards the engine timing when there is a knock or ping detected. This will make the car a little sluggish. It is rare that the knock sensor goes bad.
The knock sensor is located under the Intake Manifold and there is a knock sensor 1/ knock sensor 2 on this model,the 2 is the one in the rear.
