OBD-II Trouble Code Technical Description
Charge Air Cooler Temperature Sensor Circuit Bank 1
What does that mean?
This diagnostic trouble code (DTC) is a generic powertrain code, which means it applies to OBD-II equipped vehicles that have a charge air cooler temperature sensor (Chevy, Ford, Toyota, Mitsubishi, Audi, VW, etc.).
Although generic, the exact repair steps may vary depending on make/model. A turbocharger is basically an air pump used to force air into the engine. Inside, there are two sections: the turbine and the compressor.
The turbine is attached to the exhaust manifold, where it is driven by exhaust gases. The compressor attaches to the air intake.
