Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for other transmission-related codes that may help provide further insights into the issue. | OBD-II Scanner |
| Inspect Transmission Range Sensor | Visually inspect the transmission range sensor for signs of wear, damage, or misalignment. Use diagnostic tools to test its operation. | Multimeter, Diagnostic Scanner |
| Check Mechanical Linkage | Inspect the mechanical linkage for disconnections, wear, or misalignment that could be preventing the vehicle from shifting into sixth gear. | Flashlight, Safety Gloves |
| Inspect Transmission Internals | If no external problems are identified, inspect the internal transmission components, such as the gears and clutch plates, for signs of wear or damage. | Transmission Tools, Diagnostic Scanner |
| Replace Faulty Components | Replace any damaged sensors, wiring, or internal transmission components as necessary to restore proper gear function. | Replacement Parts, Wrenches, Screwdrivers |
| Clear the Code and Test Drive | After repairs, clear the code using an OBD-II scanner and take the vehicle for a test drive to confirm the problem has been resolved. | OBD-II Scanner |
| Recheck for Codes | After the test drive, rescan the vehicle to ensure the P074E code has not returned. | OBD-II Scanner |
