P0920 on Kia
Gear Shift Forward Actuator Circuit/Open
P0920 on Kia vehicles indicates gear shift forward actuator circuit/open. Au7o has documented this code across 2 Kia models — most commonly on Niro, Stinger. 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.
Common Causes of P0920
- •Open or broken wiring in the actuator circuit
- •Faulty gear shift forward actuator
- •Corroded, loose, or disconnected connector
- •Moisture or corrosion on circuit contacts
- •Damaged wiring harness near the transmission
- •Poor ground or open power feed to the actuator
- •Faulty transmission control module (less common)
P0920 on Kia by Model
Kia Niro(1 issue)
- Dual-Clutch Transmission Judder (Hybrid)2017-2022
The 6-speed dual-clutch transmission (DCT) in the 1st generation Niro Hybrid (2017-2022) develops a juddering or shaking sensation when starting from a stop and during low-speed gear changes. The dry clutch pack wears and develops uneven friction surfaces, causing the shudder. This is most noticeable in stop-and-go traffic and typically appears between 25,000-40,000 miles. The issue is exacerbated by the frequent clutch engagement/disengagement required by the hybrid system.
Kia Stinger(1 issue)
- 8-Speed DCT Harsh Shifting and Delayed Response2018-2023
The 8-speed wet dual-clutch transmission in the Stinger exhibits harsh low-speed shifts, delayed response when pulling away from stops, and occasional gear hunting on hills. The DCT clutch pack adapts over time but the adaptive learning can drift, leading to rough shifts. TCU software updates have improved shift quality. In rare cases, clutch pack replacement is needed.

What does P0920 mean on Kia?▼
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 Kia specifically, this code is documented across 2 models.
