Ags Sensor

I have a 2015 dodge dart 2016 and having problem with the ags sensor. I first used the obd ex scanner that read code P0117 for my temperature sensor so I replaced the temperature sensor and read my car with the obd mx+ and got code U11E9. The symptoms I am having seems like an overcharge of my fan radiator that blows extremely hard and causes my car to shake. I have read post about the ags sensor but no one talks about that symptom. Why is the ags sensor overworking my radiator fan and how can I fix it. I cleaned off connectors and made sure it is plugged in all the way but nothing changed.

There is no such thing as an AGS sensor. The AGS actuator gets a signal from the PCM through the white/red LIN bus wire. If you searched for the diagnostic, it would have told you to use a multimeter to find the wiring fault. The PCM isn't communicating with the AGS actuator and to prevent overheating which would happen if the shutters were closed, the PCM turns on the radiator fan. Fix the wiring fault.

The violet/red wire to the positive probe and black wire to the negative probe should have 12 volts with the ignition on at the disconnected AGS connector. The white/red wire should be checked for continuity. Disconnect each connector end from the PCM and the AGS actuator and use the ohm scale on the multimeter with a probe at each end of that white/red wire. You should get a low reading less than 5 ohms.
There are you tube videos about using a multimeter.
You have a AGS code. Fix the AGS and then do the PROXI.

Again, it's not a sensor, it's an actuator motor. Any motor needs a positive wire and a negative wire as well as a switch. Since you are getting a communication code, it's likely the PCM isn't getting or sending a signal. You need to find the wiring fault whether it's an open or short to ground or voltage. Use your multimeter, find the fault and fix it.

Yes I changed the temperature sensor and I get confused so my apologies idk if you read my other replies but I did test them and explained what I got. Here’s my reply “Back with an update! the white/red has no continuity. I did get 12 volts with the violate/red wire but there was another violate or red wire on the end that I got nothing from.. I think it is the actuator grill shutter by looking at the diagram.” So going forward I am asking what is the next step how do I fix the problem? Sorry if I’m aggravating you I’m just a girl trying to figure things out

If you can find a 2015-16 Chrysler 200 at a self serve junkyard those harnesses to the AGS actuator are longer. Cut and splice to your harness. There will only be 3 wires so figure out which violet/red wire on your connector is redundant (not used). Any splice should be soldered and covered with adhesive lined heat shrink tubing. Anything else will corrode and not last. The following video shows how to do a proper splice. Instead of the small brass crimps, you can take a single strand and wrap the spliced wires to hold them together while soldering. To get a single strand, you need to strip off the insulation from a 3 inch length of wire. Harbor Freight sells adhesive lined heat shrink tubing and calls it Marine heat shrink tubing. If you don't have a solder iron, get at least a 60 watt solder iron. Harbor Freight also sells a nice heat gun for the heat shrink tubing.

Those straw things are heat shrink tubing but the only way to tell if they are adhesive lined is to shrink one over a wire to see if adhesive oozes out.
Be sure to use only resin core solder not acid core solder.

The violet/red wire with a black heat shrink is a redundant wire that doesn't get soldered to anything. No idea why it's even there because it doesn't do anything. You only need to splice the other 3 wires.
That is the correct type of solder.

Back with another update: I did my best with soldering the wire and wrapped it with heat shrink when I was done. I turned my car on and the actuator closed and then stayed open. I read in another discussion that, that is the pcm testing the actuator. So does that mean my problem with the pcm and code ue119 is fixed?? I haven’t put it on my obd scanner again yet.
