If its a 2-3 code for the truck its the intake Air Sensor. The ECU sets the code when the intake air sensor signal voltage goes below 0.4 volts for more than two seconds. If the signal voltage returns, and is between 0.4 and 4.5 volts, for more than 2 seconds, the light goes out and the code is inactive.

Check your sensor. It should be.....

9,300 ohms at 32 degrees F (set in fridge)

200 ohms at 194 degrees F (in oven)
