I looked in the information I have and could not find that code. I found P1492 and P1493. These are for the battery temperature sensor. Maybe someone with Chrysler experience will come by.
P1494 is the code for the leak detection pump and or system, which is part of the early evaporative emission system. (Fuel tank fumes)
It’s there to allow the computer to run an integrity test of the fuel tank, lines and carbon canister’s ability to contain all of the fumes coming from the tank and all line associated with the system.
The code could be set for a number of reasons such as a faulty gas cap, cracked vacuum lines, solenoids & vent valves stuck to the pump itself.
It can be a very difficult fault to cure being it doesn’t take a very big leak anywhere in the system to set the code and that’s if it’s a leak and not an electrical or mechanical fault.
Good luck and keep us informed of what you find.
Dan.
Anybody else here had REAL good results pulling the EVAP canister and mounting it upside down for a good 10 mile 70mph freeway drive? A sure sign of someone who likes to top off the tank.
