Electronic Throttle Control

I am a little concerned because I got into my 2008 Jeep Liberty this morning and the Electronic Throttle Control warning light came on as well as the tire pressure (which didn't concern me because this often happens when there is a drastic change in the weather) as well as the Electronic Stability Program/Traction Control System Indicator Light. There were no warning signs or issues leading up to this. I went online and found that there were several write ups with similar issues. I bought the vehicle used so I'm not even sure what my options are... any advice? I can't afford a ton of repairs on this vehicle, that's why I traded my old vehicle in for this one. HELP!!

Just throwing this out there:
How's your battery? You'd be amazed at the different trouble codes (DTC) that are set after a jump start.

You don't think you Liberty was flood damaged (before you bought it) do you?

I wouldn't mess with this one. Get it flat decked into a repair shop and have them look at it. I hate fly by wire throttles in vehicles now...a buddy of mine was sitting at a traffic light and the ECM decided to go haywire and went WOT. He was lucky to be able to hold it back with the brakes and got it shut down before it went out into traffic.

Yes, get it checked out IMMEDIATELY. The perfect series of events might be slim to none to cause your electronic throttle control to go haywire, but it happens more often than it should..

Get a warranty?

Thought I would post here instead of a new thread but my check engine, ETC, and Service 4WD lights all came on. I took it in and they said it was running hot and seemed to be leaking antifreeze. Could that be causing all the lights to come on or are there possibly other problems as well?

The check engine is definitely from the leaking fluid.

What did you run over or hit?? The three at the same time is odd.

Don't know. I drove 350 miles and no light, then it sat for about 24 hours and went I started back up they were all on. Ended up having the water pump and serp belt replaced. I'm out of town so not much of an option other than driving home with a couple gallons of coolant to add.

You could check (load test) your battery and clean terminals and wires. Check wiring and connections to the TPS and wiring to the transmission.
