Q: What does code P08A1 mean?

Gear Lever Y Position Sensor 2 Circuit Low. P08A1 indicates that the powertrain control module has detected a low voltage condition on the signal circuit for the Gear Lever Y Position Sensor 2, which is a secondary sensor used to confirm the fore-aft position of a joystick-style or electronic gear selector. The computer expects a voltage within a calibrated range and sets this code when the signal falls below the minimum threshold, indicating a short to ground, an open circuit, or a faulty sensor.
