Lights On My Truck

scratch that...........I thought yer truck was newer.................I guess I dont know on a 99.....there is no sensor on the air inlet on a 99
maybe its in the intake manifold ????
AIT sensor maybe...............Bingo I think we have a winner
AIT is back of the motor drivers side just below injector #6

Ok I will check that I guess when it stops raining if not Im taking my headlights out

ok thank you much.
With my luck its probably some rare sensor that is on back order for 6 months and cost 500.00

[lukesdiesel] The heater system consisted of the air-heater unit mounted on the intake manifold cover, the microprocessor mounted on the left side of the dashpanel, two relays on the left inner splash shield, and a temperature sensor in the intake manifold.
luke informed me of this so I guess its more than one spot that could be bad

The more I think about it, this seems to be the problem.
Heres some info for diagnosing the sensor:
http://www.dodgeram.org/tech/dsl/sensors/IAT/clean.htm
Give it a good cleaning with some electrical contact cleaner (or brake cleaner if you are in a pinch) and see what happens. This thing isnt real easy to get to - you will likely have to lay on the valve cover.
They are not expensive either...

The IAT sensor measures the temperature of the intake manifold. The ECM uses this sensor reading to set injection timing and adjust the air-fuel ratio. If the fuel mileage and power output of you engine seem low, some owners have found improvement in EGT, fuel economy, and power after cleaning carbon from the IAT sensor in at the rear of the intake manifold. Engine with exhaust brakes are particularly prone to IAT sensor fouling because soot is blown back into the intake during valve overlap. Smokingdiesel.com has an information page about problems caused by the IAT sensor.
The only tool you need is a 3/8" ratchet with a 6" extension and 13/16" socket.
The IAT sensor is found on the driver's side of the engine, almost at the back of the intake manifold.
