P2724 — Pressure Control Solenoid "E" Stuck On

OBD2 code P2724 flags a problem with the automatic transmission control (pressure control solenoid "E" stuck on). Short, gentle driving to a shop is usually possible. Common culprits: low or degraded transmission fluid, failed shift or pressure control solenoid, faulty transmission speed sensor.

powertrain (engine/transmission)

Is it safe to drive?

Drive with caution Drive only if the transmission still shifts predictably, and avoid highway speeds. Driving with slipping or limp mode accelerates internal wear — every kilometre can add to the final repair bill.

How to diagnose with an OBD scanner

  1. Read the code and freeze frame Connect an OBD2 scanner, confirm P2724 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
  2. Check for companion codes and TSBs Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many P0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
  3. Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the automatic transmission control for damage, corrosion, chafing or poor contact.
  4. Subsystem check Command the pressure control solenoid "E" on and off with a scanner and watch the feedback signal; then remove and inspect the mechanism for sticking before replacing it.
  5. Subsystem check Check transmission fluid level and condition — dark, burnt fluid points to internal wear.
  6. Subsystem check Read transmission-specific codes and live data (solenoid states, input/output speed) with a capable scanner.
  7. Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P2724 does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for P2724 (parts and labor, USD, independent shop rates): Replace a shift solenoid: $300–$800; Transmission rebuild or replacement: $2,500–$5,500; Valve body repair or replacement: $700–$1,500; Transmission fluid service: $150–$350. Overall, fixing P2724 usually costs between $150 and $5,500. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.

Common questions

How do I diagnose P2724 myself?

Start with a scan: confirm P2724, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the pressure control solenoid "E", and verify the suspect component against live data before buying parts.

How much does it cost to fix P2724?

Replace a shift solenoid — $300–$800; Transmission rebuild or replacement — $2,500–$5,500; Valve body repair or replacement — $700–$1,500; Transmission fluid service — $150–$350. Exact cost depends on the root cause, your vehicle and local labor rates — a proper diagnosis is the cheapest first step.

What is the most common cause of P2724?

The most common causes are: low or degraded transmission fluid, failed shift or pressure control solenoid, faulty transmission speed sensor.

Will P2724 clear itself?

Sometimes P2724 clears after a few drive cycles if the fault was intermittent — for example a loose connector or a tank of bad fuel. The underlying cause usually remains, so the code tends to return. Clear it once; if it comes back, diagnose rather than erase it repeatedly.

What does OBD2 code P2724 mean?

OBD2 code P2724 flags a problem with the automatic transmission control (pressure control solenoid "E" stuck on). Short, gentle driving to a shop is usually possible. Common culprits: low or degraded transmission fluid, failed shift or pressure control solenoid, faulty transmission speed sensor.

What does P2724 mean?

P2724 is logged by the onboard diagnostics when the automatic transmission control does not behave as expected. The official definition is “Pressure Control Solenoid "E" Stuck On”. This is a powertrain (engine/transmission) category code.

“Stuck” means the pressure control solenoid "E" is commanded to change state but feedback shows it does not move — or moves when it should not. Typical physical reasons are carbon or dirt jamming the mechanism, welded relay contacts, or a weak actuator.

This code does not appear from a single bad reading: the module must see the fault condition repeat under defined operating conditions before it turns on the warning light. The freeze frame captured with P2724 — engine load, rpm, temperature, speed — tells you exactly when the problem occurs, so reproduce those conditions when testing.

Common symptoms of P2724

  • no movement in severe cases
  • slipping between gears
  • transmission stuck in one gear (limp mode)
  • Check Engine or transmission warning light on
  • harsh or delayed shifting

What causes P2724?

  • welded relay contacts keeping the circuit permanently on
  • mechanism of the pressure control solenoid "E" jammed by carbon, dirt or corrosion
  • weak actuator motor or broken spring
  • failed shift or pressure control solenoid
  • faulty transmission speed sensor
  • valve body wear
  • low or degraded transmission fluid
