Question
How to diagnose faulty throttle position sensor (TPS) in drive-by-wire systems?
Answer
Monitor TPS voltage output and test for smooth voltage transitions.
Explain
A faulty TPS causes erratic throttle response. CHEPQ tools measure TPS voltage (0.5-4.5V across range) and check for voltage drops—replacing the sensor restores smooth acceleration and idle control.
