what happens if you disconnect throttle position sensor

Disconnecting the throttle position sensor (TPS) can lead to various engine performance issues and potential damage. The TPS provides critical information to the powertrain control module (PCM) about the position of the throttle plate, which is used to set the air-fuel mix. If the TPS is disconnected, the PCM will not receive this information, and it may not be able to adjust the air-fuel mix correctly, leading to issues such as engine stalling, rough idling, poor acceleration, and reduced fuel efficiency. In addition, disconnecting the TPS can cause the engine to enter limp mode, which is a safety feature that limits engine power to prevent further damage. Its important to keep the TPS connected and functioning properly to ensure the engine runs smoothly. If you suspect that the TPS is faulty, its recommended to have your car serviced by an expert mechanic to diagnose and fix the issue.
