What P2815 means
P2815 is the opposite electrical case: the driver of solenoid G sees battery voltage where the load should pull the pin down. In GM's 2016 eight-speed table, where G is the converter clutch pressure valve, the flag must stand for 0.3 s of a 0.5 s window and one trip is enough. The 2023 Corvette dual-clutch software, with G as the limited-slip valve, also books two further checks here: estimated current deviating from target by over 70 % for 60 ms or by 200 mA for 300 ms, and a short to a neighbouring output found during the shutdown test and set at the next start, rated Type B. Ford lists a shorted load on the TR9070 even clutch cooling valve under this code. Check the harness for contact with a supply wire before replacing parts.
P2815 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyHard
- Typical labor1 to 6 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2815
- MIL lit and transmission in a substitute program
- Harsh engagement or missing converter lockup
- Code may appear only after the next engine start (shutdown test)
Common causes of P2815
- Most likelyControl wire of solenoid G touching a supply voltage wire
- PossibleSolenoid coil with shorted turns drawing too much current
- Less likelyTwo solenoid outputs shorted together inside the harness or valve body
- Less likelyFaulty driver stage in the transmission module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2815 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 8 | Area: transmission. |
| 15 | The exact fault in that area. |
What to do next
- Note P2815 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 P2815
What does P2815 mean?
P2815 means "Pressure Control Solenoid G Control Circuit High". P2815 is the opposite electrical case: the driver of solenoid G sees battery voltage where the load should pull the pin down. It is a generic code, so it means the same on every make.
Is it safe to drive with P2815?
Drive gently and only to a workshop. With P2815 the car can go into limp mode (reduced power) to protect itself.
Will P2815 fail an emissions test?
Yes, it can. P2815 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 P2815 to fix?
Difficulty: hard. A typical repair takes 1 to 6 hours of work. This is a job for a workshop.
Will P2815 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
