ECT Sensor Circuit

Diagnostic & Technical Explanation
Code P008F (Engine Coolant Temperature/Fuel Temperature Correlation) sets when the ECM sees an open, shorted, or implausible resistance from an engine or radiator coolant temperature sensor, or a correlation mismatch between redundant coolant/oil/ambient temperature signals. Causes are a corroded connector, a failed thermistor element, low coolant exposing the sensor tip, or chafed wiring.

These 44 diagnostic trouble codes share one detection mechanism and one repair path, which is why MechanicDB groups them into a single authored fault family rather than repeating the same explanation 44 times.
