2001 Pontiac Grand Am 2.4L SFI DOHC 4cyl
Vehicle Speed Sensor - Location:
The speed sensors are built right into the wheel bearings of your vehicle, at the front and rear locations. They work both with the anti-lock brakes and with the traction control systems on the vehicle.
I hope help you with this (remember rated this help) Have a nice day, good luck.

Hello! Here is a picture of the location of the front knock sensor for a 3.8 liter V6 3800 Series II (97-03)
(Please note that the engine is upside down on the stand)
There are 2 knock sensors on this engine, one on the front (as shown), and another in the rear. There isn't one on the driver's side, per se.
I recommend that you let the vehicle cool down before beginning this process. To remove this you will need a drip pan, as coolant will leak from the engine when the sensor is removed. You will need a deep well 22mm socket and torque wrench.
1. Jack up and support the vehicle on jack stands so that you can work from underneath the vehicle. Be sure to apply your emergency brake.
2. Identify the knock sensor location and remove the electrical connector on the bottom.
3. Using the deep well socket, remove the sensor from the block. Do not position yourself direcly underneath this, as coolant will begin to flow immediately from the sensor's location.
4. Your new knock sensor should come pre-coated with sealant/threadlock, just install it and tighten by hand until snug.
5. Torque the sensor to 14 ft lbs.
6. Replace the electrical connector.
7. You should flush the entire coolant system to be sure to remove any air pockets, and then refill.
Hope this helps and thanks for using FixYa!

Here is a diagram of the firing order for you 3800 engine. Cylinders 1 and 4 are misfiring because the operate under the same "Coil Pack" and the coil pack has unfortunately gone bad. O'Reilly sells them for between $30-50 depending on the amount of warranty coverage you want. To replace, simply unscrew the screws that hold the coil pack in place. WAIT before unplugging the plug wires. Place the old coil pack and new coil pack next to each other, unplug one plug wire, then plug it to that same port on the new coil pack. then do the same for the other plug wire. Then screw your new coil pack in place, and start you car. should run fine!
