What P0998 means
Low-voltage fault, typically a short to ground, in the control circuit of shift solenoid F. Two makers document it. Nissan lists P0998 as shift solenoid F in bulletin NTB15-037 for the 2012–2017 Versa, Versa Note and Sentra with the RE0F11A CVT, whose two-speed auxiliary gearbox uses a low brake, a high clutch and a reverse brake; if the shop manual check points to the transaxle, the bulletin has only the control valve replaced. Mitsubishi's 2019 service manual for a six-speed automatic names P0998/P0999 the low clutch shift solenoid valve system and counts it among faults that can cause gear ratio errors. CARB requires transmission outputs to be checked for circuit faults. P0999 is high, P097F open.

Symptoms of P0998
- Check engine light
- Limp mode or loss of a gear range
- Harsh engagement or flare when shifting
Common causes of P0998
- Most likelySolenoid or valve body (control valve) internal fault
- PossibleControl wire shorted to ground in harness or connector
- Less likelyTransmission control module driver fault
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0998 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. |
| 98 | The exact fault in that area. |
What to do next
- Note P0998 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 P0998
What does P0998 mean?
P0998 means "Shift Solenoid F Control Circuit Low". Low-voltage fault, typically a short to ground, in the control circuit of shift solenoid F. It is a generic code, so it means the same on every make.
Is it safe to drive with P0998?
Drive gently and only to a workshop. With P0998 the car can go into limp mode (reduced power) to protect itself.
Will P0998 fail an emissions test?
Yes, it can. P0998 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 P0998 to fix?
Difficulty: hard. A typical repair takes 1 to 5 hours of work. This is a job for a workshop.
Will P0998 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
