Code P2EC1: Turbocharger Compressor Outlet Temperature Sensor Circuit High
Diagnostic & Technical Explanation
Code P2EC1 (Turbocharger Compressor Outlet Temperature Sensor Circuit High) covers the sensor measuring charge-air temperature right at the turbocharger compressor outlet, used to protect the intercooler and downstream plastic components from a hot-side temperature spike and to trim charge-air density calculations. The ECM flags an open, shorted, out-of-range, or implausible signal. Causes are a sensor element degraded by sustained high-boost heat, a corroded connector, or damaged wiring routed near the charge pipe.
