What P2722 means
P2722 is the base code for pressure control solenoid E and leaves the type of fault open. No manufacturer documents P2722 publicly. The pattern can be seen on the neighbouring valve: Toyota stores P2713 for solenoid D with a failure type byte appended, so a scan tool would show the same structure for E. GM and Ford instead publish dedicated codes for E, from P2723 (stuck off) and P2724 (stuck on) to P2727, P2729 and P2730 for the circuit. On GM's eight-speed valve E feeds clutch 5, on its nine-speed the C5 clutch, on the Allison 1000 the solenoid GM calls PCS 1, and on the 2023 Corvette and Ford TR9070 dual-clutch units the line pressure pilot valve. CARB covers such solenoids as comprehensive components.
P2722 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor1 to 12 hours
- Clears after repairAfter a drive cycle
Symptoms of P2722
- MIL lit with possible further transmission codes
- Irregular shifting or fail-safe gear
- Engagement delay into drive or reverse
Common causes of P2722
- Most likelySolenoid E sticking or failing
- PossibleWiring or connector problem on the solenoid E circuit
- PossibleContaminated or low transmission fluid
- Less likelyTCM fault
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2722 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 7 | Area: transmission. |
| 22 | The exact fault in that area. |
What to do next
- Note P2722 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 P2722
What does P2722 mean?
P2722 means "Pressure Control Solenoid E". P2722 is the base code for pressure control solenoid E and leaves the type of fault open. It is a generic code, so it means the same on every make.
Is it safe to drive with P2722?
Drive gently and only to a workshop. With P2722 the car can go into limp mode (reduced power) to protect itself.
Will P2722 fail an emissions test?
Yes, it can. P2722 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 P2722 to fix?
Difficulty: workshop only. A typical repair takes 1 to 12 hours of work. This is a job for a workshop.
Will P2722 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.
