P2723 OBD-II Trouble Code: Clutch Pressure Control Solenoid 5 - Stuck Off

check engine light

P2723 code definition

A P2723 fault code refers to a problem with the clutch pressure control solenoid 5 circuit. The solenoid may be faulty, which can cause shift issues.

What the P2723 code means

P2723 indicates a problem with the electrical circuit for the clutch pressure control solenoid 5 in the transmission. If a given engine setting doesn't result in a proper pump pressure, the vehicle's computer will log the P2723 code. Left unchecked, this issue can result in a less efficient use of power or an inability to shift gears.

What causes the P2723 code?

A few things may be the cause of a P2723 code:

  • Hydraulic fluid blockages in the internal transmission system.

  • Low transmission fluid levels.

  • A faulty transmission, control solenoid, or PCM module.

What are the symptoms of the P2723 code?

The symptoms of a P2723 can vary wildly. At worst, the vehicle may be unable to change gears or engage the clutch. Less severe symptoms can include weaker fuel efficiency and problems with handling the vehicle's transmission. A dashboard malfunction light or Check Engine Light and stored P2723 code also function as diagnostic symptoms of this issue.

How does a mechanic diagnose the P2723 code?

A OBD-II code reader will indicate the P2723 code if one has been logged on the vehicle's computer. The transmission fluid should be checked to see if the levels are sufficient, as well as whether the fluid itself is clean. Following that, a mechanic will inspect the transmission in order to confirm the issue. Results should be compared with the manufacturer's default settings and used to help pinpoint the root problem if necessary.

Common mistakes when diagnosing the P2723 code

Although many are quick to blame a faulty module for this issue, the problem may lie with a malfunction in the wiring or the solenoid itself. These typically involve less expensive repairs, and should be ruled out before investing in other replacement parts.

How serious is the P2723 code?

At worst, a P2723 code can result in the vehicle's complete inability to shift gears and a failure to engage the clutch. In many cases however, a P2723 may have no noticeable effects. Nonetheless, it is important to fix the problem as soon as possible. This will prevent the solenoid problem from getting worse.

What repairs can fix the P2723 code?

If a given part of the transmission or solenoid circuit is faulty, it will need to be replaced. The car should be tested following repairs to ensure the problem has been solved. Common repairs include replacement of the clutch pressure control solenoid, replacement or repair of the transmission, or possibly replacement of the PCM or TCM.
