- How the car detects it
- With indirect charge air cooling, a water-to-air charge air cooler cools the charge air; it sits in a separate low-temperature coolant circuit with an electric pump and its own radiator. The charge air cooler coolant temperature sensor A measures the coolant temperature of this circuit. The control module uses it to control the pump and to monitor cooling performance. Documented users are diesel engines from Ford and GM. P00E2: The signal jumps or drops out briefly, which typically points to a loose contact or a chafed harness.
