P099AShift Solenoid G Control Circuit Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- The drive circuit of shift solenoid G is electrically intact, but current or voltage feedback does not fit the command. No manufacturer was found to document this code. The two documented users of the G control circuit codes report only the hard faults: Mitsubishi's 2019 six-speed (low-reverse brake shift solenoid) uses P099B for a short and P099C for an open, and Nissan's RE0F11A CVT lists P099B/P099C. Hyundai and Genesis report their on/off solenoid G under P075A and P075D. The slot would follow the pattern FCA uses for solenoids 2 to 5 (P0975 to P0984, control circuit performance). CARB requires transmission outputs to be checked for function. Low and high are P099B/P099C, open P09A0.
- What you may notice
- Warning light depending on calibration
- Harsh or missing shifts involving this solenoid
- Possible limp mode
- Likely causes
- LikelySolenoid coil resistance out of specification
- PossibleHigh-resistance connector or harness contact
- RareWeak driver stage in the transmission control module
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
