P0115 Code: Easy Steps to Solve It
The P0115 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the Engine Coolant Temperature (ECT) sensor circuit. This code is triggered when the Powertrain Control Module (PCM) detects an erratic or irrational input signal from the ECT sensor, which is crucial for regulating engine performance and emissions. Understanding this code is essential for vehicle owners and DIY mechanics, as it
