P2725 OBD-II Trouble Code: P2725 – Press Ctrl Solenoid E Electrical

Check Engine Light

P2725 Code Definition

The P2725 code is a generic powertrain code related to an issue with the transmission or gear box. In this case, it means an abnormality has been detected in the electronic pressure control solenoid or solenoid circuit E.

Codes related to the P2725 include:

  • P2722: Pressure Cntrl Solenoid E
  • P2723: Pressure Cntrl Solenoid E Performance or Stuck Off
  • P2724: Pressure Cntrl Solenoid E Stuck On
  • P2726: Pressure Cntrl Solenoid E Intermittent
  • P2727: Pressure Cntrl Solenoid E Cntrl Circuit/Open
  • P2728: Pressure Cntrl Solenoid E Cntrl Circuit Range/Performance
  • P2729: Pressure Cntrl Solenoid E Cntrl Circuit Low
  • P2730: Pressure Cntrl Solenoid E Cntrl Circuit High

What the P2725 Code Means

The engine control module (ECM) regulates hydraulic pressure through electronic pressure control solenoids. Varying amounts of hydraulic pressure provide the pressure for shift actuation and torque converter lock up. The automatic transmission utilizes a high pressure pump to circulate the fluid through the transmission hydraulic circuits.

If the vehicle’s ECM sees an abnormality in the E pressure control solenoid, a P2725 code will be stored. Using throttle position, engine load, and engine and vehicle speed, the ECM determines the correct pump pressures needed for proper vehicle operation. If the pressure varies from predetermined levels, a fault code is stored.

What Causes the P2725 Code?

Several problems may cause a P2725 code including:

  • Low or dirty/contaminated transmission fluid
  • Damaged or defective electronic pressure control solenoid
  • Damaged or defective transmission control module
  • Clogs or blockages in transmission hydraulic fluid passages
  • Damaged or defective transmission
  • Damaged or defective ECM (rare)

What are the Symptoms of the P2725 Code?

Symptoms of a P2725 code may include:

How Does a Mechanic Diagnose the P2725 Code?

A mechanic may use several methods to diagnose a P2725 trouble code, including:

  • Utilize an OBD-II scanner to check for a stored P2725 trouble code
  • Check transmission fluid level and quality
  • Check for possible debris and contaminants in the transmission pan
  • Visually inspect related wiring and electrical connectors and components for damage or corrosion
  • Check for possible transmission fluid leaks
  • Check hydraulic pump pressure with a manual pressure gauge
  • Check electronic pressure control solenoid E reference voltage and ground signals
  • Utilize a digital volt or ohmmeter to check circuits for continuity and resistance

Common Mistakes when Diagnosing the P2725 Code

One common mistake made when diagnosing a P2725 code includes overlooking wiring malfunctions or issues with the electronic pressure control solenoid, resulting in the unnecessary replacement of high pressure pumps.

How Serious is the P2725 Code?

Because a vehicle’s safe driving operation is may be impacted due to faults that store a P2725 code, this is considered a potentially serious code. When this code appears, it is recommended that you take your vehicle to a service center or mechanic for diagnosis and repair as soon as possible.

What Repairs can Fix the P2725 Code?

Several repairs can fix a P2725 trouble code and include:

  • Fill and/or flush the transmission to replace transmission fluid
  • Possible total rebuild of transmission and replacement of torque converter (if debris located in transmission fluid pan)
  • Repair or replace any damaged or faulty wires, connectors, or related components
  • Repair or replace any hoses that may be damaged or leaking
  • Repair or replace damaged or defective hydraulic pump
  • Repair or replace damaged or defective shift solenoids
  • Repair or replace damaged or defective electronic pressure control solenoids
  • Repair or replace damaged or defective electronic pressure regulator
  • Replace or repair damaged or defective torque converter
  • Replace or repair damaged or defective ECM
  • Clear all codes, test-drive the vehicle, and rescan to see if any codes reappear

Additional Comments for Consideration Regarding the P2725 Code

Often, additional transmission slippage or torque converter codes will be stored with a P2725 code, so it is always recommended to check and diagnose all potential trouble codes before vehicle repair.
