What P2817 means
P2817 means valve H fails to produce the effect it is commanded to give. On GM nine- and ten-speed automatics H is the converter clutch valve: too much slip in lock mode (130 rpm) or a large slip error in controlled mode, counted three times, sets a Type A fault. GM's PIP6005 traces the code on 2024-2025 Enclave, Traverse and Acadia with the 8T65 to a seal on the turbine shaft that was harmed when the converter went in; torque converter and seal are replaced. Honda calls H the O/P shift solenoid of its CVT: bulletin 19-047 covers 2016-2018 Civic 1.5 L, 2017-2018 CR-V and some 2018-2019 Accord, where the module misread drive pulley pressure as too high, and new software fixes it. The flashing D lamp, converter slip or poor fuel economy follow. P2818 is the reverse fault.
P2817 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor0.5 to 10 hours
- Clears after repairAfter a drive cycle
Symptoms of P2817
- MIL on or flashing D indicator
- Converter clutch slips, engine speed higher than usual at cruise
- Increased fuel consumption
Common causes of P2817
- Most likelyValve H stuck or hydraulically unable to apply
- PossibleDamaged turbine shaft seal letting converter clutch pressure escape (GM 8T65)
- PossibleMisjudged pressure signal in older control software (Honda CVT)
- Less likelyLow or degraded transmission fluid
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What to do next
- Note P2817 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 P2817
What does P2817 mean?
P2817 means "Pressure Control Solenoid H Performance/Stuck Off". P2817 means valve H fails to produce the effect it is commanded to give. It is a generic code, so it means the same on every make.
Is it safe to drive with P2817?
Drive gently and only to a workshop. With P2817 the car can go into limp mode (reduced power) to protect itself.
Will P2817 fail an emissions test?
Yes, it can. P2817 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 P2817 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 10 hours of work. This is a job for a workshop.
Will P2817 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.
