P0997Shift Solenoid F 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 F works electrically but its measured current or voltage does not fit the command. No manufacturer was found to document this code. The users of the F block, Nissan's RE0F11A CVT and a 2019 Mitsubishi six-speed, list only P0998 and P0999. FCA's nine-speed bulletin 21-019-17 (2015 Chrysler 200 and Jeep Cherokee) shows how the slot is used for solenoids 2 to 5, with P0975, P0978, P0981 and P0984 for control circuit performance, but stops before a sixth solenoid. Genesis reports an electrical fault of its solenoid F under P2709 instead. CARB requires transmission outputs to be checked for proper function. P097F is the open circuit, P0998/P0999 low and high.
- What you may notice
- Warning light depending on calibration
- Missing or harsh shifts into gears using 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.
