What P2723 means
P2723 means valve E fails to build the pressure its clutch needs, so that element slips or does not engage. GM's eight-speed table ties E to clutch 5 (C4-5-6-7-8-R) and sets the code after 400 rpm of slip lasting 3 s. On the Allison 1000 GM's tables call the valve PCS 1: if the on-coming clutch has not taken hold after 2 s of slip during a forward shift, a Type A fault follows. Bulletin PIP5100A adds a field cause: shrink-wrap from an aftermarket spin-on filter can block the PCS 1 feed hole, giving no or intermittent reverse. On the 2023 Corvette dual-clutch unit it is the system pressure pilot valve, failed when pressure stays more than 3 bar above target (Type A). Subaru lists P2723 among CVT codes in 18-241-26.

Symptoms of P2723
- Delayed, intermittent or no reverse
- Slip or flare in affected gears
- MIL on and range inhibit or fail-safe mode
Common causes of P2723
- Most likelyBlocked feed orifice in the separator plate (foreign material, GM Allison 1000)
- PossibleLow fluid level or pump losing prime, especially on cold starts
- PossibleSolenoid E or its regulator valve sticking
- Less likelyWorn clutch seals leaking apply pressure
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What to do next
- Note P2723 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 P2723
What does P2723 mean?
P2723 means "Pressure Control Solenoid E Performance/Stuck Off". P2723 means valve E fails to build the pressure its clutch needs, so that element slips or does not engage. It is a generic code, so it means the same on every make.
Is it safe to drive with P2723?
Drive gently and only to a workshop. With P2723 the car can go into limp mode (reduced power) to protect itself.
Will P2723 fail an emissions test?
Yes, it can. P2723 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 P2723 to fix?
Difficulty: workshop only. A typical repair takes 1 to 14 hours of work. This is a job for a workshop.
Will P2723 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.
