The throttle position sensor (TPS) tells the engine control unit (ECU) exactly how far the throttle is opened at any given moment. This information is critical for correct fuel delivery, ignition timing, idle control and smooth acceleration. On modern vehicles, even small inaccuracies in throttle position feedback can cause noticeable drivability problems.
When a throttle position sensor begins to fail or drift out of range, drivers may experience unstable idle, hesitation on acceleration, sudden surging, limp mode activation or poor starting behaviour. Because these symptoms often overlap with airflow and fueling faults, TPS issues are frequently misdiagnosed.
To understand how throttle position feedback works together with airflow and engine timing sensors during startup and idle, read our in-depth technical guide:
Why Modern Vehicles Fail to Start or Idle Unpredictably – How Sensors Decide Whether Your Engine Lives or Dies
Restore accurate throttle feedback and protect your engine management system by replacing a worn or faulty throttle position sensor with a quality, vehicle-specific unit.
• Always confirm whether the TPS is a separate component or integrated into the throttle body.
• Erratic voltage signals or dead spots during throttle movement are common signs of TPS wear.
• After installation, some vehicles require a throttle or idle relearn procedure to restore correct operation.
• Inspect wiring and connectors carefully, as poor connections can mimic sensor failure.
• Avoid adjusting or modifying the sensor unless specified by the manufacturer.
Delayed servicing and intake contamination can accelerate throttle and sensor wear. Learn how poor maintenance causes hidden engine damage in our servicing guide:
