Question
What causes TPS "hunting" (fluctuating voltage) in older vehicles?
Answer
Wear on sensor potentiometer and loose electrical connections.
Explain
Older TPS sensors (pre-2010) develop potentiometer wear. CHEPQ oscilloscopes show voltage fluctuations (>0.1V at steady throttle)—cleaning connections or replacing the sensor resolves hunting.
