P00DECharge Air Cooler Coolant Temperature Sensor A Circuit
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- 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. P00DE: This is the general circuit fault; low and high signals have their own codes. No manufacturer description naming this exact code was found.
