Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Engine Sensors
The CCC needs sensor inputs to determine engine operating characteristics. The following sensors are used with this system:
- Intake Airflow Sensor
- Intake Air Temperature Sensor
- Fuel Flowmeter
- Fuel Pressure Switch
- Throttle Position Potentiometer
- Closed Throttle Switch (with Back-up Circuit)
- Coolant Temperature Sensor
- Oxygen Sensor
- Engine Speed (from a distributor signal)
- Air Conditioner "On" Switch
In addition to these sensors, the CCC also receives information from the ignition switch, has a timer to determine operating time, and determines engine load by comparing airflow with engine speed.
