P2724 — Pressure Control Solenoid E Stuck

Manufacturer-specificPowertrain (engine & transmission)

The P2724 code indicates that the engine control module has detected a malfunction in Pressure Control Solenoid E, suggesting it is stuck in either the open or closed position. This solenoid is responsible for regulating the line pressure within the transmission to ensure proper gear engagement and shifting.

Symptoms

What causes it — most likely first

1. Failed Pressure Control Solenoid E

The solenoid has suffered an internal electrical failure or a mechanical jam, preventing it from moving.

2. Contaminated Transmission Fluid

Debris or metallic particles in the fluid can lodge inside the solenoid, causing it to stick.

3. Wiring Harness Damage

Frayed, shorted, or broken wires between the PCM and the solenoid prevent the correct signal from reaching the component.

4. Incorrect Fluid Level

Critically low or overfilled transmission fluid can cause pressure instabilities that trigger a stuck solenoid code.

5. PCM Failure

The powertrain control module is sending an incorrect signal or failing to process the solenoid's feedback.

How it's diagnosed

  1. Check transmission fluid level and inspect for contaminants or burnt smell.
  2. Inspect the wiring harness and connectors for signs of corrosion, chafing, or breakage.
  3. Measure the electrical resistance of the solenoid using a multimeter to verify it is within factory specifications.
  4. Perform a pinch test or use a scan tool to command the solenoid and listen for a physical click.
  5. Verify the integrity of the circuit by testing for voltage and ground at the solenoid connector.

Frequently asked

Can dirty transmission fluid cause a P2724 code?

Yes, sludge or metal shavings can physically block the solenoid valve, causing it to stick and trigger the code.

Should I replace the PCM if I have this code?

No. It is very rare for the PCM to cause this code; the issue is almost always the solenoid itself, the wiring, or fluid contamination.

Will replacing the solenoid fix the issue if the fluid is contaminated?

Not necessarily. If the fluid contains debris, the new solenoid may quickly become clogged or stuck, leading to a repeat failure.
