Throttle Position Sensor Circuit Low Input

What This Means

The Throttle Position Sensor (TPS) voltage is below the minimum expected threshold. The TPS tells the computer how far open the throttle is, which is essential for proper fuel and ignition timing.

Common Symptoms

• Engine surging or hesitation
• Sudden idle speed changes
• Vehicle may enter limp mode
• Poor throttle response

Common Causes

• Worn or faulty TPS
• Damaged wiring or connector
• Throttle body mechanical issue
• Poor ground connection
• Corrosion on sensor contacts
