It is located in the exhaust manifold, and is very easy to replace. All you need is a crow's wrench (available at auto zone in the help! section) and a 3/4 in. and 3/8 in. ratchet. Use an 11mm socket to remove the 3 bolts holding on the heat shield and the o2 sensor is directly below that on the front side of the manifold. Remove the old sensor and make sure the threads in the manifold are clean and insert the new sensor plug it into the harness and you're good to go. Now turning off the light that comes on automatically every 90k miles is a whole other story.
If you have a 2.3 or a 2.6 motor, there should just be one oxygen sensor. It will be located on the exhaust manifold. On the driver's side of the motor you should see it down by the firewall. It will have a single wire coming from it.

It appears that the 1993 Isuzu 3.2L V6 engine has just one oxygen sensor. It's a 4-wire type, located at the exhaust Y-pipe outlet. == ==
The knock sesor is located, on your Isuzu 1290, at the front of the engine. The sensor screws into the engine. Wires connect the sensor to the senor light.
I have been told it time to remove the dash and move a screw from one hole to another. This can be found on other sites. We are going to try it this weekend and see if it works.
The check engine light for the 2001 Isuzu Rodeo often comes on because of a sensor that is damaged or malfunctioning. The most common sensor is an oxygen sensor and when reset, this often allows the light to be reset.
It is inside the passenger side rear wheel well.
