P2724: Pressure Control Solenoid ‘E’ Stuck On OBD-II Trouble Code

A pressure control solenoid is responsible for maintaining the hydraulic pressure necessary to change gears. If the pressure control solenoid labeled E gets stuck in the On position, a P2724 DTC will be stored.

How Serious is the Code?

If a pressure control solenoid gets stuck On, the number drivability and safety problems will happen. Including slipping, engine stalling and limp mode (transmission only works in a single forward gear). So in a nutshell, the P2724 OBDII diagnostic trouble code is very serious.

Symptoms

Symptoms of a P2724 include:

  • Slipping out of gear
  • Erratic or unusually hard shifts
  • Engine stalling
  • Transmission won’t change out of a gear
  • Vehicle can’t move even though a forward or reverse gear is selected
  • Higher fuel consumption
  • Transmission overheats
  • Limp mode

Causes

  • Not enough ATF in the transmission
  • Transmission fluid and filter are dirty
  • The wiring and connectors may be damaged
  • Pressure control solenoid has failed
  • Transmission pump has failed
  • Fluid passages inside the transmission are blocked
  • Valve body is not functioning properly
  • TCM or ECU has failed

How to Diagnose the Code?

When diagnosing a P2724 DTC, important to note if the transmission fluid has any dirt, sludge or metallic debris. Dirt and thin fluid hydraulic pressure and prevent the solenoids from functioning properly. Metal shavings can indicate internal component failure, which is why important to change your transmission fluid in the manufacturer’s recommended schedule. If the transmission fluid is clean, then the wiring and connectors should be checked for damage and/or corrosion. If no no issues are found up to this point, then the pressure control solenoid will need to be tested, along with possibly the ECU/TCM, transmission pump or valve body.
