When it comes to Ford P0735 Code, it’s important to understand the underlying cause to make sure the issue is resolved. P0735 is a diagnostic trouble code (DTC) for “Gear 5 Incorrect Ratio”. It is triggered when the engine is operating with 5th Gear commanded “on” and the powertrain control module (PCM) detects an incorrect 5th gear ratio during the test. This code is often accompanied by other codes related to the transmission. In order to diagnose and repair the cause of this code, a technician must first understand the components involved and the possible causes of the code.
Causes and Solutions of Ford P0735 Code
| Cause | Solution |
|---|---|
| 5th Gear solenoid harness connector not properly seated | Check the connector and make sure it is properly seated. |
| 5th Gear solenoid signal shorted to ground, or open | Check the wiring harness and make sure there are no shorts or opens. |
| 5th Gear solenoid wiring harness connector is damaged | Inspect the connector for any damages and replace if needed. |
| 5th Gear solenoid is damaged or not properly installed | Check the solenoid for any damages and replace if needed. |
5th Gear Solenoid Harness Connector Not Properly Seated
The 5th Gear solenoid harness connector is designed to allow the transmission to shift into 5th gear. If the connector is not properly seated, the shift will not occur and the Ford P0735 Code will be triggered. To diagnose this issue, a technician must first inspect the connector and make sure it is properly seated.
5th Gear Solenoid Signal Shorted To Ground, or Open
The 5th Gear solenoid signal is used to control the shift into 5th gear. If the signal is shorted to ground or open, the shift will not occur and the Ford P0735 Code will be triggered. To diagnose this issue, a technician must first inspect the wiring harness and make sure there are no shorts or opens.
5th Gear Solenoid Wiring Harness Connector Is Damaged
The 5th Gear solenoid wiring harness connector is designed to allow the transmission to shift into 5th gear. If the connector is damaged, the shift will not occur and the Ford P0735 Code will be triggered. To diagnose this issue, a technician must first inspect the connector for any damages and replace if needed.
5th Gear Solenoid Is Damaged or Not Properly Installed
The 5th Gear solenoid is the component that actually controls the shift into 5th gear. If the solenoid is damaged or not properly installed, the shift will not occur and the Ford P0735 Code will be triggered. To diagnose this issue, a technician must first check the solenoid for any damages and replace if needed.
Conclusion
In conclusion, the Ford P0735 Code is triggered when the engine is operating with 5th Gear commanded “on” and the powertrain control module (PCM) detects an incorrect 5th gear ratio during the test. To diagnose and repair the cause of this code, a technician must first understand the components involved and the possible causes of the code. The possible causes of this code include a 5th Gear solenoid harness connector not properly seated, a 5th Gear solenoid signal shorted to ground or open, a 5th Gear solenoid wiring harness connector is damaged, and a 5th Gear solenoid is damaged or not properly installed. Proper diagnosis of Ford P0735 Code is essential to ensure the issue is resolved.
