The preheat function is used to warm up the inlet air during cold conditions both before and after cranking to make the starting easier and better for the environment at very low temperatures. This diagnostic trouble code (DTC) detects a faulty preheat function.

Conditions for diagnostic trouble code (DTC)
The voltage at pin A14.EB:7 is 91?%-91?% battery voltage

Observable symptoms
Preheating does not function
Difficult to start in extreme cold
