It will have two. One for the guage/light and another for the PCM and cooling fans. One will probably be located in the intake behind the alternator, and the other one, also located on the intake will be over by the upper radiator hose/thermostat housing. The one over by the alternator will be the one that signals the PCM.

code 33 is for the exhaust gas sensor (also known as the O2 sensor) if the computer is coding a 33 it does need to be changed. You can also uplug the sensor at the connector and if the truck runs better that's a good indication that the sensor is bad. The connector is on the passanger side fender wall with about 3 other connectors and it is on the bottom of the group with 3 wires running to the sensor.
