What P0997 means
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.

Symptoms of P0997
- Warning light depending on calibration
- Missing or harsh shifts into gears using this solenoid
- Possible limp mode
Common causes of P0997
- Most likelySolenoid coil resistance out of specification
- PossibleHigh-resistance connector or harness contact
- Less likelyWeak driver stage in the transmission control module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0997 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 9 | Area: transmission. |
| 97 | The exact fault in that area. |
What to do next
- Note P0997 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0997
What does P0997 mean?
P0997 means "Shift Solenoid F Control Circuit Range/Performance". The drive circuit of shift solenoid F works electrically but its measured current or voltage does not fit the command. It is a generic code, so it means the same on every make.
Is it safe to drive with P0997?
Drive gently and only to a workshop. With P0997 the car can go into limp mode (reduced power) to protect itself.
Will P0997 fail an emissions test?
Yes, it can. P0997 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0997 to fix?
Difficulty: hard. A typical repair takes 1 to 5 hours of work. This is a job for a workshop.
Will P0997 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
