How do you replace the front left wheel speed sensor on a 2002 Pontiac Grand Am SE with ABS?
I have the exact same car and the exact same problem!
for a 97-03 grand prix there is a front and rear o2 sensor. bank 1 sensor 2 is the sensor located on the exhaust near the catalytic converter (cat) also known as the REAR sensor... bank 1 sensor 1 is located on the back of the engine on top of the exhaust manifold or headers would be the street term. thats the FRONT sensor.
To replace a Pontiac Grand Am bumper cover, start by taking out either the three bolts on the side of the fender or in front of the wheels. Remove the top pushpins to remove the cover. Push back the two pins for each headlight, and pull them up. Unplug the lights. Then, get the replacement bumper, and snap it into place like the previous one.
