When this system malfunctions, it can greatly impact the vehicle's performance and drivability.
Common Causes of P1193
- Faulty electronic throttle control unit
- Malfunctioning throttle position sensor
- Wiring or connector issues
- Dirty or faulty throttle body
- Electronic control module (ECM) failure
Symptoms of P1193
- Reduced power and acceleration
- Engine running at low RPMs
- Check engine light illuminated
- Rough idling or stalling
- Limited top speed
