So i've been trying to figure out this dang ambient temp sensor issue. I tested the sensor it OHM reads exactly as the repair manual states. I get 3-4volts on the pink/black wire.
My AC and heat only work on max lol
As far as i know this circuit has nothing to do with the engine harness but this used to work on my old harness, and fast forward to this revision with new harness and it doesn't work.
Missing ground somewhere?
Did I unplug something under the dash?
Shares grounds with trac ecu or something that i removed?
I used to own a 2017 that was basically brand new and i was always afraid of scratching it or damaging it, this BAH whatever haha.
Thanks Rudy I LOVE IT.
Okay new slew of things ive ran into lol.
Thought i blew the car up it had some ticking/knocking action going on at idle. Turns out my IACV came loose and was moving around under the intake, fixed that today.
I noticed a new issue though! Warm car up to temp (180 ISH degrees on the standalone), do one pull and it drops a whole notch on the temp gauge.
Once it comes back up to temp again, it doesn't do this action again. I've never seen a car do this...
I'm going to try and get a log of it happening.
Current theories:
Air in system still?
My thermostat is sticking upon that first use?
??? lol

They're so damn nice to have around! I use mine constantly and can't justify getting rid of it for any reason.
Phew! Glad to hear that was an easy fix. I do suppose you could have some air in the system... I also suppose that with a nice upgraded cooling system that as soon as you get some serious air moving through and that WP moving fast it could cool slightly... I haven't had that experience except on an older Civic Si of mine. I did an aluminum radiator, silicone hoses, etc and it would always run cooler than stock as long as it was moving. It sucked during the winter because the heater would only catch up when you sat there and idled lol.
