I have a 03 dodge neon i get code p0499 whitch means vent control seloniod circuit high what could cause that?
3 things could cause this code, the nvld vent valve has failed internally, the wiring to this component has an issue, or the engine control computer itself has failed. the nvld vent valve is in the rear of car, near the charcoal canister and vent filter. check resistance across pins on nvld corresponding to orange wire and white/dk grn wires. ensure black wire has good chassis ground. if no probelms found, disconnect pcm connector 3 (white), and check continuity of orange wire and white/dk wires (pins 8 and 35 if memory serves me). if problem is still not found, then the engine control module most likely needs to be replaced. hope this helps

Can a short circuit cause low voltage?
Most likely a short circuit will cause no voltage. Due to the high current on a short circuit fault the over current protection of the circuit will trip. This will cut the voltage supply off completely.
