P2724
Pressure Control Solenoid E Stuck On
Automatic transmission
Generic OBD-II
Medium
What it means
P2724 means transmission pressure control solenoid 'E' is stuck on — it keeps applying pressure when the control module expects it to release. The result is usually harsh or slipping shifts, being stuck in gear, or a limp mode. This is a transmission-side fault; the engine still starts and runs normally.
Medium
Can I keep driving? Drivable, but shifts may be harsh, slipping, or delayed and the transmission may go into limp mode. The engine still starts normally.
