I drive a 2014 Chrysler 200 LX with 2.4 liter engine and automatic 4 speed transaxle with 97800 miles. I seem to be having an issue between my traction control system and my throttle body. It used to disappear if I turned the traction control system off before starting, car ran fine, now that trick no longer works and I have to creep around town barely doing the speed limit. There are no fault codes displayed on my dash, but I get a flashing red throttle body light and a steady yellow traction control active light as soon as I start my engine. My Idle has gone from normal 900 RPM to 1500, I can not rev past 3 grand and my acceleration is very sluggish. I have asked several online mechanics about it and one said it was my MAP sensor, but why was I able to bypass the problem by turning my traction control off? Another said it was a bad wheel sensor in my ABS system which is causing my traction control to activate, even when I am not moving. Another said my throttle body is bad, the traction control is getting bad data from a sensor on the throttle body. I would love to know what you think, please. I know you are not a fan of 200's, but it has been a good car except for replacing the headlight bulbs (like doing body work to reach them) and the stupid battery inside my bumper cover which was a tight fit to replace. Thanks for your opinion.
The same sensors (wheel speed, trans gear, throttle etc.) that are involved in your traction control feed the same key data to the engine control unit (ECU computer). If one is giving bad data, or the connectors are funky, both things could misbehave. It's not unknown to have 2 problems that happened at the same time.
Do the MAF sensor and throttle body clean per Scotty's video, then I'd get a wiring diagram and go through these key systems with some contact cleaner and emery paper and make sure all your connectors are clean, shiny, properly seated. You may need to hook up a good scanner if that doiesn't give results.
