SOURCE: where do i find a knock sensor a 1993 gmc sierra

Should be on the right side of the engine by the starter.Has a 1 wire connector.It does not go into the cooling system so you can just take it out without draining the coolant.Hope this helps.Good luck.

You will have to remove the intake manifold to gain access to the knock sensors. There are two sensors in the valley under rubber plugs. The sensor in the rear has a tendency to fill up with water and cause trouble. You have to make a dam with RTV to stop the water from getting in there.

SOURCE: 2003 GMC Sierra Knock sensor and oil pressure??

the knock sensors are located below the intake plenum,or,upper intake manifold as some call it, they screw into the lower intake, the front one is sensor 1, the rear is sensor 2. it is wise to change both if you have some miles.since you are going to be buying a gasket set to do this job.the sensors are cheaper than the gaskets.

Where is the knock sensor located on a 2010 GMC Terrain


Being that you have a terrain, your problem is NOT the knock sensor. Locate the 17 digit VIN on your vehicle and contact a dealer and see if there is a timing chain recall that pertains to your vehicle. The problem is the bank one chain actuator is not adjusting properly. I've had to repair a number of these, and it's costly(12-1600.00 and NOT for a DIY'er
