The P0935: Hydraulic Pressure Sensor Circuit High refers to an issue where the hydraulic pressure sensor circuit is receiving higher than expected voltage. This can cause incorrect pressure readings, leading to improper transmission behavior.
P0935 – Quick Overview
| Code | Information |
|---|---|
| Meaning | P0935: Hydraulic Pressure Sensor Circuit High |
| Is it serious? | Yes, high voltage can cause incorrect pressure readings and potentially harm transmission performance. |
| Possible causes | – High voltage in the hydraulic pressure sensor circuit – Faulty hydraulic pressure sensor – Wiring or connector issues |
| How to diagnose? | – Check the circuit for high voltage – Inspect wiring and connectors – Replace the hydraulic pressure sensor if necessary |
P0935 Meaning
The P0935: Hydraulic Pressure Sensor Circuit High code indicates that the voltage in the hydraulic pressure sensor circuit is above the required level, causing improper pressure readings. This can affect the transmission’s ability to operate correctly, leading to shifting problems or transmission damage over time.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for any additional codes that may provide further insights into the issue. | OBD-II Scanner |
| Inspect the Wiring and Connectors | Visually inspect the wiring and connectors related to the hydraulic pressure sensor for damage, corrosion, or disconnections. | Flashlight, Multimeter |
| Test for High Voltage | Use a multimeter to check for high voltage in the hydraulic pressure sensor circuit. Compare the readings to the manufacturer’s specifications. | Multimeter |
| Check the Hydraulic Pressure Sensor | Test the hydraulic pressure sensor for proper functionality. Replace it if it is defective or out of range. | Diagnostic Tool, Replacement Sensor |
| Clear the Code and Test Drive | After repairs, clear the code using an OBD-II scanner and perform a test drive to confirm the issue is resolved. | OBD-II Scanner, Vehicle Owner’s Manual |
| Recheck for Codes | Re-scan the system to ensure the P0935 code does not reappear after the test drive. | OBD-II Scanner |
