    Vehicle:
    1996 Tacoma 2.7 4x4 extended cab
    33" bfg mud terrains, cold air intake, flowmaster with side exhaust, manual swapped, manual hub swapped, lifted on bilsteins
    So after figuring out how to clear all my trans related codes after swapping to manual I've still got P0125 (insufficient coolant temp for closed loop fuel control). I've replaced the upstream o2 sensor, and cleaned my MAF. The ECT was replaced a couple months ago (advance auto part). I'm reading 185 degrees after the truck gets warm, voltage looks to be normal on the front o2 sensor, and getting good readings from the MAF. Could the aftermarket ECT sensor be giving bad readings and making the light come on? Any help would be appreciated.
