Guys there is an update- the mechanic scamed me, there was nothing wrong with the sensor. The issue was the wire connecting key sensor and power was rusty and causing loose contact which inturn caused my car to shut off.

Bad parts, any sensor should be OEM or a brand that is known to work for that specific sensor. Unfortunately there is a plague of bad parts especially electronics

There's a mechanical fault causing the sensor to read outside of the allowable tolerances making the module its linked to send a message that something is wrong.

Well, I have a question I was told by a diagnostic that my knock sensor is bad I see you’re in Arizona I’m in Arizona myself I’m in Mesa a was sold pretty much a lemon I was told all that was wrong with my alignment and the check engine light was on because of a gas cap When I have had to replace my rack and pinion my axle might oil pan gasket I transmission pan gasket my alternator, my starter and my knock sensor needs to be replaced. I don’t know how to get to it and I was told it inside or underneath the manifold do you have any advice for a young lady that has no clue what to do I just conquered stage four terminal cancer and my brother bought me this vehicle and I haven’t been able to move it in a month since I bought it. It drove for one week and I went to go make a U-turn and I pressed on my guess and my car just Stolt, I thought it was my alternator then I was told it was my fuel pump, but under diagnostic it shows that the knock sensor is bad. Do you have any advice for me?
