P0765 OBD-II Trouble Code: Shift Solenoid D Malfunction

check engine light

P0765 code definition

Detecting the P0765 code means that the PCM is reporting an abnormality in the function of the shift solenoid D, which manages the transfer of hydraulic fluid between circuits in the transmission.

What the P0765 code means

The shift solenoid D is part of the transmission system; it helps to manage the transfer of fluids between circuits, and to change transmission gear ratios. This solenoid is directed by the ECM, which monitors the solenoid’s voltage reading to ensure that it is working correctly. If the ECM attempts to open the shift solenoid D valve, and receives an improper voltage reading, it will alert the PCM to store the P0765 code.

What causes the P0765 code?

There are several things that could cause the shift solenoid D to appear to be malfunctioning. One of the main causes for the P0765 code is a faulty shift solenoid D; however, other causes may include:

  • Blocked internal transmission fluid passages.
  • Failures in the transmission.
  • Low transmission fluid.
  • Dirty transmission fluid.
  • Faulty shift solenoid D valve.
  • Open or shorted shift solenoid D valve circuit.
  • Faulty PCM or TCM in some rare cases.

What are the symptoms of the P0765 code?

In some cases, there may be no detectible symptoms with the P0765 code. In many cases, the illumination of the Check Engine Light will be accompanied by an inability to shift gears, a slipping transmission, an overheating transmission, decreased fuel efficiency, and the presence of other OBD-II codes related to the shift solenoids.

How does a mechanic diagnose the P0765 code?

After verifying the P0765 code with an OBD-II scanner, the mechanic should begin by inspecting the transmission fluid. The fluid should be at the proper level, and should be clean. If it is not, these issues should be remedied. After ensuring that the transmission fluid is clean and full, the mechanic should perform a visual examination of any wiring or electrical components, and ensure that none are loose, corroded, open, or shorted.

These repairs should be followed by clearing the code from the PCM and performing a retest. If the code returns, the mechanic has diagnosed an issue within the shift solenoid system, and can move on to other repairs.

Common mistakes when diagnosing the P0765 code

The most commonly reported misdiagnosis with the P0765 code is immediately replacing the shift solenoid D, rather than considering that the shift solenoid circuit is at fault. Electrical errors are frequently to blame for this code, and a thorough diagnosis should be performed before any components are replaced.

It is common to overlook clearing the P0765 code and retesting after each potential solution is performed. If the most common repairs do not stop the code from being stored again, it can be a sign of an intermittent issue that requires an in-depth inspection and more complex repairs.

How serious is the P0765 code?

The P0765 code represents a very serious error that should be addressed as soon as it is detected. This issue relates directly to the driver’s ability to shift gears, and could represent dangerous vehicle performance, or a total inability to operate the vehicle at all.

What repairs can fix the P0765 code?

In order to repair an issue that is causing the P0765 code to be stored in the PCM, a technician may perform the following fixes:

  • Replacing a faulty shift solenoid D.
  • Clearing blocked internal transmission fluid passages.
  • Addressing internal mechanical failures in the transmission.
  • Replacing or refilling dirty or low transmission fluid. If the fluid was exceptionally dirty, the entire transmission may need to be disassembled and flushed.
  • Replacing faulty shift solenoid D valve.
  • Repairing or replacing open or shorted shift solenoid D valve circuit.
  • Replacing faulty PCM or TCM in some rare cases.
