The "high trans temp" light isn't on, but does the engine high idle to circulate fluid when it believes the transmission is hot but not "so hot I need to light the dummy light"? The ECT is used by ECM which then feeds a signal to the dashboard gauge, correct? Or are they a parallel circuit with the gauge and the ECM reading the same sensor but not affecting one another? I ask because the gauge reads the way it always does, but if it's a parallel path then the wire feeding the ECM could have an issue and make it up the idle, right? The fact it all started with the transmission service is the odd thing to me. I reconnected that while the engine was running, and to absolutely no surprise at all nothing happened with the idle.Ī bad ECT sensor reading low will cause high idle While crawling under the truck, I noticed my red CAD vacuum line worked its way out of the elbow (again). Could I have done something wrong in the valve body work to cause this? Pressure/temperature sensor connection wasn't removed, and I did push on it just to make sure it was still connected before putting it all back together. The 8-way electrical connector went back together exactly as one would expect, smooth with a nice click. This issue also came up IMMEDIATELY after transmission service. Is it possible that I have a lot of oil blowby though the turbo causing such a problem? I have strong doubts that's the problem because the truck drives the same as always and the idle is super stable. As a side note, the air filter is newish and still very clean. Will read the OBDLink with engine off before unhooking batteries to make sure it reads 0 PSIG, ~14 PSIA, or equivalent in metric. Hoping a little battery-free reset will do some good.Ī fellow here also recommended I check to make sure the MAP sensor is reading correctly, that "if he recalled correctly" the MAP sensor reading can trump the ECM's desire to idle at 850ish. Meant to unhook batteries when I got to work but forgot. In.No tuner of any kind, though I do desire to purchase one! SLT Night Runner Sport Standard Cab Pickup 2-Doorĥ.9L 359Cu.
