Throttle Position Sensor (TPS) - Signs of Failure and Maintenance Guide
Common Signs of TPS Failure
Check Engine Light
One of the first indicators of TPS issues is an illuminated check engine light, often accompanied by trouble codes P0120 to P0124.
Sudden RPM Changes
The engine may suddenly surge or drop in RPM while driving at a consistent speed, even without pressing the accelerator pedal.
Poor Acceleration
Vehicle may experience delayed or jerky acceleration, or feel like it's hesitating when you press the gas pedal.
Rough Idle
The engine might idle roughly or stall unexpectedly when coming to a stop.
Poor Fuel Economy
A failing TPS can cause the engine to run rich or lean, resulting in decreased fuel efficiency.
Maintenance Schedule
Regular Inspection
The TPS should be inspected during routine maintenance, typically every 60,000 miles or when symptoms occur.
Cleaning
The throttle body and TPS should be cleaned every 30,000 miles to prevent carbon buildup that can affect sensor readings.
Calibration Check
Professional diagnostic testing should be performed if any symptoms appear or during major tune-ups.
Replacement
While there's no specific replacement interval, most TPS units last 80,000 to 100,000 miles under normal conditions. However, replacement is recommended when signs of failure appear.
Important Note: These are general guidelines. Specific maintenance schedules may vary by vehicle make, model, and driving conditions. Always consult your vehicle's owner's manual or a certified technician for precise maintenance requirements.
