Hi, The first item is, which O2 sensor? there are two of them so I'll give you both. As I look at the schematic I can see the O2 sensor #1 is Pink and Red/Blueink goes to D19/C23 Red/Blue goes to B8/A2. O2 sensor #2 has Yellow or Red/Blue (it can be either or) and Pink/White or Pink/Blue (again it can be either or). O2 sensor #1 is at the manifold and O2 sensor #2 is by the Catalytic convertor. I avoided the confusion by purchasing the ones with the plugs attached so I don't remember what the price difference was. I hope this was in time for you and good luck. Steve H.
The 1990 Geo Tracker IAT sensor is located on the top of the transmission. The IAT sensor will be near the back of the transmission.
The IAT Sensor on a 1992 Geo Tracker is the Intake Air Temperature Sensor. Replacing the air filter might fix this problem.
The speed sensor for a 1996 Geo Tracker is located on the transmission housing. The speed sensor is important , it keeps track of the tires and delivers the figures to the main system
there isn't one
Not sure what the question is. What, Where etc...
on the hrottle body
in the distributor
in the dist.
The IAT ( Intake Air Temperature ) sensor is located on the back of the air cleaner housing.
Its on the Air box
