Frequently asked questions
What does P0920 mean on a Dodge?
P0920 stands for "Gear Shift Forward Actuator Circuit/Open." P0920 indicates an open circuit in the gear shift forward actuator circuit. In transmissions that use electronic shift actuators, this actuator helps engage forward gear ranges; an 'open' means the control module isn't seeing a complete electrical circuit to that actuator. The code is treated as serious because it can prevent the transmission from shifting or engaging gears properly. Symptoms may include inability to select or stay in a forward gear, harsh or no engagement, a transmission warning light, or limp-mode behavior. On Dodge it is documented across 1 model: Dart.
