P2722Pressure Control Solenoid E
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- 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.
