The circuit 1 knock sensor would be located on the lower right side of the engine block (passenger side). You will need to drain the coolant from the radiator and be prepared for the passenger side of the block to drain coolant when the knock sensor is removed. After you disconnect the electrical connection to the knock sensor, the knock sensor simply unthreads from the block counterclockwise. Apply a thread sealant to the threads of the new sensor and install, no need to over tighten, this is a tapered pipe thread.
To change a fuel vapor sensor on a 1997 GMC Sonoma you need to disconnect the wires that are holding it in place. Next, remove the old sensor and replace with the new one.

Check the Sonoma crank position first. If the sensor is bad then there will be no spark from the coil.
