Fix P0774: STEP-BY-STEP diagnostic GUIDE!

The P0774: Shift Solenoid E Intermittent fault refers to an issue where shift solenoid “E” operates inconsistently, causing erratic or delayed gear shifting. This may result from a faulty solenoid, wiring issues, or poor electrical connections.

P0774 – Quick Overview

CodeInformation
MeaningP0774: Shift Solenoid E Intermittent
Is it serious?Yes, intermittent solenoid performance can lead to unpredictable shifting and drivability issues.
Possible causes– Intermittent issues with shift solenoid E
– Faulty solenoid
– Wiring or connection issues
How to diagnose?– Test solenoid E for intermittent faults
– Inspect wiring and connectors
– Replace faulty solenoid if necessary

P0774 Meaning

The P0774 code indicates that shift solenoid “E” is experiencing intermittent operation. This solenoid controls the flow of transmission fluid, and inconsistent performance can lead to irregular or delayed gear shifts, affecting the vehicle’s drivability.

Step-by-step diagnostic guide

ActionDescriptionTools Needed
Check for Other CodesUse an OBD-II scanner to check for any additional transmission-related codes that may provide more insight into the problem.OBD-II Scanner
Test Solenoid E for Intermittent FaultsUse a multimeter or diagnostic scanner to test solenoid E for electrical continuity and performance under different conditions. Check for signs of intermittent function.Multimeter, Diagnostic Scanner
Inspect Wiring and ConnectorsInspect the wiring and connectors leading to solenoid E for damage, loose connections, or corrosion that could cause intermittent faults. Repair or replace as necessary.Flashlight, Multimeter, Safety Gloves
Check Transmission FluidVerify that the transmission fluid is at the correct level and is clean, as low or dirty fluid can affect solenoid performance. Adjust fluid level if necessary.Transmission Fluid Tester, Dipstick
Replace Faulty SolenoidIf solenoid E is found to be malfunctioning intermittently, replace it with a new solenoid according to manufacturer specifications.Replacement Parts, Wrenches, Screwdrivers
Clear the Code and Test DriveAfter replacing the solenoid, 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 P0774 code has not returned.OBD-II Scanner
