P2726
Pressure Control Solenoid E Intermittent
Transmission
Generic OBD-II
Medium
What it means
P2726 means the transmission control module saw an intermittent or erratic signal from pressure control solenoid "E," which regulates shift hydraulic pressure. Because it comes and goes, it often points to a loose connector or chafed wire rather than a dead solenoid. Expect occasional harsh shifts or brief limp mode; the engine starts and runs normally.
Medium
Can I keep driving? Usually drivable — shifts may glitch or briefly go to limp mode and recover; the engine starts and runs fine.
Common symptoms
What you'll notice
- Check-engine light on (may come and go)
- Occasional harsh or slipping shifts
- Momentary limp mode that clears itself
- Reduced fuel economy
Common causes
Most likely first
- Intermittent open or short in pressure control solenoid E wiringLikely
- Loose or corroded solenoid connectorCommon
- Dirty or contaminated transmission fluidCommon
- Failing pressure control solenoid ELess often
- Chafing internal transmission harnessLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame and note the conditions when the fault appears.
- Wiggle-test the solenoid connector and harness for intermittent contact.
- Inspect the internal transmission harness for chafing.
- Check fluid level/condition and the solenoid resistance.
- Repair wiring or replace the solenoid; clear and road-test over several cycles.
FAQ
Quick answers
Is it safe to drive with P2726?+
Usually yes for short trips, since the fault is intermittent and often recovers. But harsh shifts stress the transmission, so have the wiring and solenoid checked before it becomes constant.
Can I just clear P2726?+
Because it's intermittent, it may stay away briefly after clearing but returns once the loose connection or solenoid acts up again. Track down the intermittent contact to fix it for good.
