I have 98 Pathfinder and I've had three mechanics try and determine why my check engine light is on. They all said it has to do with emissions but can't specify what's wrong. One mechanic thought it could be the fuel pump but wasn't 100 percent sure that could be the problem.
I am trying to sell the truck this week and need to get the light off.
Has anyone had similar issues or know why the light could be on?

You need to find out what the stored codes are before we can help you. Most parts stores retrieve OBDII codes for free with a code reader, or you can do the manual method to pull manufacturer codes. That procedure can be found at www.troublecodes.net/Nissan/"

Did you perform the diagnostic procedure per the FSM and confirmed the knock sensor is faulty or are you assuming the sensor is bad solely because there is a stored code for knock sensor? The knock sensor is located under the intake manifold, so replacing it is not easy and you'll want to be sure that it's actually the sensor itself that threw the code before reassembly. It's not a job you want to do twice! As far as sensors, you can find them running anywhere from $36 to over $200. The sensors are expensive because of the precious metals used in them. With this in mind, one has to wonder if the cheap, aftermarket sensors are made to the same standard as the original Nissan part? If the sensor was in an easy spot to get to, I might take a chance on a low cost part, but with the labor involved to get to it, personally, I would stick with genuine Nissan. The MSRP for a genuine Nissan knock sensor is $209.17, but you can get it for $150.60+shipping from 1stAAANissanParts.com
