P1116Coolant temperature sensor out of self-test range

  • Ford code · Engine
How the car detects it
During a scan-tool self-test the coolant temperature (ECT) sensor reading was outside the range the test expects. Ford asks for more than about 10 °C for the engine-off test and more than about 82 °C (fully warm) for the engine-running test, so a cold engine is a common reason.
