Throttle Body Injection Troubleshooting
Throttle Body Injection Troubleshooting The throttle body in a car provides the control of air and fuel injection so that the system runs efficiently and does not backflow. When this automotive part is not working correctly, or its electronic sensors begin firing off readings to the onboard diagnostic computer showing problems, it can create car problems. Not only does a malfunctioning throttle body have the capability to cause the check engine light to come on, it can also cause other sensors to overcompensate, causing other problems elsewhere. Typical related issues will include the oxygen sensor and the mass air flow sensor. As a result, automotive diagnostics of a troublesome throttle body can include a process of elimination with other parts as well.
