P2428 LINCOLN Description
The Powertrain Control Module (PCM) monitors the Exhaust Gas Temperature (EGT) sensor for a biased signal value. Following an 8-hour soak, the PCM records the EGT sensor temperature value at key ON, engine OFF. After several minutes of vehicle operation at vehicle speeds greater than 40.2 km/h (25 mph) the PCM calculates an expected key ON, engine OFF value. The PCM determines what the expected EGT value at key ON, engine OFF should have been based on inputs from other sensors. The test fails when the difference between the expected calculated value and the actual recorded value is greater than 40°C (72°F).
