2003 Mitsubishi Lancer P0117 Fault Code: Causes and Solutions
I'm experiencing an OBD2 fault code P0117 on my 2003 Mitsubishi Lancer. The code indicates a sensor circuit malfunction in the engine coolant temperature sensor, which is causing the vehicle to enter limp mode or reduce power under load. This issue typically occurs when the coolant temperature sensor fails to provide accurate readings to the ECU. I've checked the wiring and connections, but the problem persists. Any advice on how to diagnose or fix this code would be greatly appreciated.
