P099CShift Solenoid G Control 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
- High-voltage fault in the control circuit of shift solenoid G. Mitsubishi's 2019 six-speed uses P099C for an open circuit of the low-reverse brake shift solenoid: with the solenoid commanded off and transmission relay voltage of 2 V or more, a reading of 3.7 V or more for 0.5 s sets the code. So on this design an open shows up as high, not under P09A0. The drive cycle needs only 10 s with the ignition on. Causes named are the harness, connectors, the TCM and the solenoid in the valve body. Nissan lists P099C as shift solenoid G for the 2012–2017 Versa, Versa Note and Sentra with the RE0F11A CVT, with control valve replacement as the fix. P099B is the low side, P099A performance.
- What you may notice

- PossibleOpen solenoid coil inside the valve body
- RareControl wire shorted to voltage
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
