Spirit R/T L4-135 2.2L DOHC Turbo (1991)
Charge Temperature Sensor: Description and Operation
Coolant And Charge Temperature Sensors
The Charge Temperature Sensor (CTS) is mounted in the intake manifold. The sensor element extends into the manifold airstream to measure the
temperature of the air passing through the intake manifold. As the temperature changes, the resistance of the sensor changes. The engine controller
reads the resistance changes and uses this information to calculate the proper air/fuel ratio and turbocharger boost level for the engine.
