BigMike4747 Posted November 5, 2018 Report Share Posted November 5, 2018 Hi, I’m new to this forum, and am having an issue with my sisters 2009 Dodge Journey. She was in an accident and was hit in the driver front of the vehicle, not a lot of damage in the engine compartment, Replaced the radiator but other than that mainly cosmetic damage. Since the accident she’s having some electrical issues, check engine light comes on occasionally, lightning bolt comes on occasionally, rides rough, sometimes car loses power and won’t start. I think we’ve narrowed down the problem to the ECM. I think this because one of the plugs has moisture in the plug and sometimes has a small amount of liquid in the plug, and after I blow it out with a compressor and dry it. It’ll run fine for about a week, before moisture builds up again and it starts to run rough again. My question is has anyone ever heard of this? And where could the fluid/moisture be coming from? I’ve blown it out thoroughly about a dozen times and moisture/liquid still manages to come back. I’ve covered it with a bag, and it continues to happen which means some how the moisture is related to the plug or computer. I swapped out the computer and it still happened. So I’m assuming it’s the plug that’s “leaking” moisture into the ECM but I don’t understand how that could be possible. Any help would be greatly appreciated!!

2late4u Posted November 5, 2018 Report Share Posted November 5, 2018 i believe the lighting bolt sign you are talking about is the throttle body light Quote Link to comment Share on other sites More sharing options...
BigMike4747 Posted November 5, 2018 Author Report Share Posted November 5, 2018 Thank you 2late4u for your response, I believe you’re correct. I’m pretty sure I remember reading that somewhere as well. Do you think the throttle body error could be related to the moisture causing the ECM to malfunction?

jkeaton Posted November 5, 2018 Report Share Posted November 5, 2018 (edited) Has it been repaired yet? Can you identify the liquid? Edited November 5, 2018 by jkeaton Quote Link to comment Share on other sites More sharing options...
BigMike4747 Posted November 5, 2018 Author Report Share Posted November 5, 2018 It has not been repaired yet, I can’t seem to find where the liquid is coming from. I haven’t identified the liquid either, it feels like an antifreeze but is yellow in color opposed to the usual green, although when I first saw the liquid it did appear more green than it does now.

CSD Posted September 5, 2019 Report Share Posted September 5, 2019 Did you ever find the exact source of this liquid? I have the EXACT same problem on a 2010 Journey 3.5L. All of your symptoms and locations are exactly the same as mine. I've taken the ECM box apart and the gel over the circuit board seemed to be in excellent condition. Thanks.

BigMike4747 Posted September 5, 2019 Author Report Share Posted September 5, 2019 Sure did, took a little while though. The antifreeze was getting into the computer thru a wire. The “coolant temperature sensor” some how malfunctioned and cracked internally allowing cooling to leak from the pressurized system thru the wire to the computer. Changed the sensor and tried to let the wire air out as much as possible and she’s driving fine now. Part was maybe $20. 2late4u, greenturtle and Summer Solstice 3 Quote Link to comment Share on other sites More sharing options...
