6+ What Happens If You Disconnect TPS? (Risks!)

The throttle position sensor (TPS) provides critical data to the engine control unit (ECU) regarding the throttle plate’s angle. This information allows the ECU to calculate the appropriate amount of fuel and ignition timing for efficient engine operation. Disconnecting this sensor results in the ECU receiving no throttle position signal, leading to a variety of potential issues.

Proper TPS functionality is paramount for smooth acceleration, fuel efficiency, and overall engine performance. Its absence can cause the engine to enter a default or “limp” mode, restricting power and increasing fuel consumption. This safeguard is implemented to protect the engine from potential damage due to incorrect fuel and ignition settings. Initially, carburetors handled fuel delivery mechanically; however, electronic fuel injection, coupled with sensors like the TPS, offered greater precision and control.
