The P0773: Shift Solenoid E Electrical code refers to an electrical issue with shift solenoid “E.” This problem can disrupt the transmission’s ability to shift properly. It can be caused by faulty wiring, a malfunctioning solenoid, or poor connections.

P0773 – Quick Overview

CodeInformation
MeaningP0773: Shift Solenoid E Electrical
Is it serious?Yes, electrical problems with the solenoid can lead to improper shifting and drivability issues.
Possible causes– Electrical issues with shift solenoid E
– Faulty solenoid
– Wiring problems
How to diagnose?– Test solenoid E for electrical faults
– Inspect wiring and connectors

P0773 Meaning

The P0773 code indicates that the transmission control module (TCM) has detected an electrical fault in shift solenoid “E.” This solenoid controls the flow of transmission fluid, allowing for smooth gear shifting. Electrical problems can prevent it from functioning properly, leading to erratic or improper shifts.

Step-by-step diagnostic guide

ActionDescriptionTools Needed
Check for Other CodesUse an OBD-II scanner to check for additional transmission-related codes that could give more insight into the issue.OBD-II Scanner
Test Solenoid E for Electrical FaultsUse a multimeter or diagnostic tool to check the electrical continuity and functionality of solenoid E. Ensure it is receiving the proper voltage.Multimeter, Diagnostic Scanner
Inspect Wiring and ConnectorsInspect the wiring and connectors leading to solenoid E for signs of damage, corrosion, or loose connections that could be causing electrical issues.Flashlight, Multimeter, Safety Gloves
Check Transmission FluidEnsure that the transmission fluid level is correct and the fluid is clean, as low or contaminated fluid can affect solenoid performance.Transmission Fluid Tester, Dipstick
Replace Faulty SolenoidIf solenoid E is found to be faulty, replace it with a new solenoid according to manufacturer specifications.Replacement Parts, Wrenches, Screwdrivers
Clear the Code and Test DriveAfter replacing the solenoid or addressing wiring issues, clear the code using an OBD-II scanner and test drive the vehicle to confirm the issue is resolved.OBD-II Scanner
Recheck for CodesAfter the test drive, rescan the vehicle to ensure the P0773 code has not returned.OBD-II Scanner
