Ford P117B: Exhaust Gas Temperature Sensor Correlation - Bank 1
OVERVIEWWhat Does The Ford P117B Code Mean?
The powertrain control module (PCM) monitors the 3 exhaust gas temperature (EGT) sensors at key ON, engine OFF, following an 8-hour soak to determine if a concern is present. The PCM compares the values of the 3 EGT sensors to verify the sensors correlate to each other. The test fails when the temperature difference at one of the EGT sensors is greater than 25°C (45°F).
