Question
How does throttle position sensor (TPS) idle position calibration diagnosis ensure stable idle?
Answer
It verifies correct TPS baseline at closed throttle.
Explain
Incorrect idle position calibration causes unstable idle. CHEPQ diagnostic tools monitor TPS idle voltage, detect drift, and guide recalibration procedures. This ensures the ECU receives accurate idle position data, maintaining stable engine idle.
