The Throttle Position Sensor (TPS) is an essential component in monitoring the position of the throttle plate, allowing the Engine Control Unit (ECU) to adjust engine speed and power output accordingly. Types of TPS: • Variable Resistance TPS: Adjusts resistance as the throttle position changes. • Digital TPS: Uses digital signals to communicate the throttle position to the ECU. Signs of a Faulty TPS: • Engine Stalls: Unexpected engine shutdowns. • Surging: Fluctuating engine performance. • Check Engine Light (CEL): Indicator light on the dashboard. • Erratic Acceleration: Unpredictable speed changes. • Loss of Power: Reduced engine performance. • Engine Misfires: Irregular engine firing. • Rough Idle: Unstable engine idle. • Increased Fuel Consumption: Higher fuel usage. • Black Smoke from Exhaust: Indicates a rich fuel mixture. • Engine Shudders: Shaking at idle.
