DTC P0773 Shift Solenoid E Electrical

Within the intricate systems governing a vehicle’s transmission, the Diagnostic Trouble Code (DTC) P0773 sheds light on concerns specifically related to Shift Solenoid E’s electrical components. This comprehensive guide aims to elucidate the meaning, potential causes, symptoms, diagnostic procedures, and effective remedies associated with the issue indicated by the P0773 code.

1. What does P0773 code mean?

The P0773 code signifies electrical issues linked to Shift Solenoid E as detected by the Transmission Control Module (TCM). It indicates irregularities or disruptions in the electrical signals affecting the proper functioning of this solenoid responsible for controlling specific gear shifts within the transmission.

2. What are the causes of DTC P0773?

The activation of the P0773 code may stem from various factors, including:

  • Faulty Shift Solenoid E: Electrical malfunctions affecting the solenoid’s engagement or operation.
  • Wiring or Connector Problems: Damaged wiring, loose connections, or corroded connectors disrupting electrical signals to the solenoid.
  • Transmission Control Module (TCM) Issues: TCM irregularities impacting the transmission’s ability to control solenoid functions.

3. What are the symptoms of DTC P0773?

When the P0773 code is present, several symptoms might become evident, including:

  • Check Engine Light Activation: Illumination of the check engine light due to electrical issues with Shift Solenoid E.
  • Abnormal Shifting: Irregular or harsh shifting between specific gears due to disrupted electrical signals affecting the solenoid.
  • Transmission Slipping or Failures: Potential transmission slipping or failure to engage gears correctly due to electrical disruptions impacting solenoid operation.

4. How to diagnose DTC P0773?

For an accurate diagnosis related to Shift Solenoid E’s electrical issues:

  • OBD-II Scan: Utilize a diagnostic scanner to retrieve the P0773 code and accompanying codes for a comprehensive analysis.
