This control system helps maintain stability and control by managing the engine's deceleration rate, especially in situations where sudden changes in engine speed could impact vehicle dynamics.
Common Causes of C0243
- Faulty engine drag control module
- Malfunctioning throttle position sensor
- Wiring or connection issues within the system
- Vacuum leaks affecting engine performance
- Issues with the engine's internal components affecting drag torque regulation
Symptoms of C0243
- Loss of engine power or acceleration
- Decreased fuel efficiency
- Rough or erratic engine idling
- Illuminated check engine light
- Unusual engine noises during deceleration
