| Is it serious? | Yes, the vehicle’s drivability will be affected as it will not shift out of third gear, limiting performance. |
| Possible causes | – Transmission stuck in gear 3 – Faulty transmission range sensor – Mechanical issues |
| How to diagnose? | – Inspect transmission range sensor – Check mechanical linkage and transmission internals – Replace faulty components if needed |
P072E Meaning
The P072E code signifies that the transmission is stuck in third gear, preventing the vehicle from shifting either up or down. This may lead to poor acceleration and reduced fuel efficiency. The issue is often related to a faulty transmission range sensor or mechanical linkage problems, though internal transmission damage could also be the cause.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to see if any additional transmission-related codes are present, which might provide further insights. | OBD-II Scanner |
| Inspect Transmission Range Sensor | Visually inspect the transmission range sensor for signs of damage or wear. Test its functionality using diagnostic tools. | Multimeter, Diagnostic Scanner |
| Check Mechanical Linkage | Examine the mechanical linkage of the transmission for disconnections or damage that could cause the transmission to stick in third gear. | Flashlight, Safety Gloves |
| Inspect Transmission Internals | If no external problems are found, inspect the transmission’s internal components for potential mechanical failures. | Diagnostic Scanner, Transmission Tools |
| Replace Faulty Components | Replace any damaged or malfunctioning components such as sensors, wiring, or internal transmission parts. | Replacement Parts, Wrenches, Screwdrivers |
| Clear the Code and Test Drive | After repairs are completed, clear the code using an OBD-II scanner and take the vehicle for a test drive to confirm that the issue is resolved. | OBD-II Scanner |
| Recheck for Codes | After the test drive, rescan the vehicle to ensure that the P072E code has not returned. | OBD-II Scanner |
