  1. P0920 Gear Shift Forward Actuator Circuit/Open High

    The P0920 code means the forward gear shift actuator circuit is open, so the component gets no current when the computer commands it. The gears may refuse to engage. Check the fuse, relay, connector and wiring before you replace the actuator.
