P2792Gate Select Direction Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2792 reports a gate select direction signal stuck above its valid band. Common reasons are a short between the signal line and a supply voltage, a broken sensor ground that lets the input float up, or an open signal wire on inputs with an internal pull-up resistor; a sensor with a failed output stage can also hold the line high. Which hardware provides the signal, actuator sensor or lever module, depends on the maker, and none of them documents P2792 publicly with limits. The test belongs to the out-of-range checks of CARB 13 CCR 1968.2 for transmission inputs. P2791 is the low-side counterpart and P2790 the general circuit fault. Typical effects are blocked sideways selection, shifts limited to one lane and a transmission warning.
- What you may notice
- Sideways selection blocked, shifts possible only in one lane
- Gearbox may stay in gear or neutral
- Transmission warning lamp
- Likely causes
- LikelySignal wire shorted to a supply voltage
- PossibleBroken sensor ground or open signal line pulled up internally
- PossibleSelect direction sensor failed with high output
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
