Description of DTC code P0752

Vehicles with automatic transmissions have a determined amount of shift solenoids, which are used to manage the transmission fluid flow through the various transmission channels. These solenoids tell the control module if the pressure with which the fluid is sent is the right to achieve the gear changes properly.

If the PCM (Powertrain Control Module) determines that the shift solenoid "A" has a lock-up condition, the fault code P0752 OBD2 will be set.

Symptoms of fault code P0752

  • The Check Engine light turns on.
  • The transmission slips.
  • High levels of transmission temperature.
  • Loss of fuel efficiency.

Causes of OBD2 P0752

Reasons for setting the P0752 OBDII diagnostic code:

  • The transmission fluid may not be at the proper level.
  • The filter or transmission fluid may be polluted.
  • Possibly there is damage to the valve body.
  • There may be obstructions in the channels through which the fluid circulates.
  • There may be components with certain imperfections in the solenoid circuit.

Possible solutions of the DTC code P0752

To properly troubleshoot DTC P0752 OBD2, try this:

  • Consult the Technical Service Bulletins.
  • Check that the condition and level of the transmission fluid are appropriate for the transmission to work properly. If you detect contaminating elements or a low level due to leaks, make the necessary repairs or changes.
  • Check all wiring and respective connectors associated with the "A" solenoid circuit. Fix or replace any of these that show damage or inconsistencies.
  • Check the continuity of the circuit and the solenoid wiring. The readings you obtain should be equal to 0 ohms unless otherwise indicated by the manufacturer. Likewise, check the resistance of the solenoid. Make any necessary repairs or changes.
