This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer thinks the sensor that checks the pressure of the hydraulic system is giving a reading that's too high.
The P0935 code is triggered when the Powertrain Control Module (PCM) detects a voltage signal from the hydraulic pressure sensor that is higher than expected.
The hydraulic pressure sensor is responsible for monitoring the pressure within the hydraulic system of the vehicle. This sensor sends a voltage signal to the PCM, which expects the signal to be within a certain range. If the signal is too high, it indicates a possible issue with the sensor or the circuit, prompting the P0935 code.
• Check Engine Light is on
• Transmission may not shift properly
• Poor vehicle performance
• Faulty hydraulic pressure sensor
• Wiring issues such as short circuits
• Faulty PCM
PCM: Powertrain Control Module
OBD-II: On-Board Diagnostics, Second Generation
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors related to the hydraulic pressure sensor.
• Test the hydraulic pressure sensor for proper operation.
• Replace the hydraulic pressure sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Wrench set

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly inspect sensor wiring for damage.
• Ensure hydraulic system is properly maintained.
• Use quality replacement parts.
Sensor Issue
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional if you notice shifting issues.
• Regular maintenance can prevent sensor issues.
Check with your vehicle manufacturer for specific warranty coverage related to sensors.
This code has been associated with sensor failures in vehicles with high mileage or poor maintenance.
Moderate – It should be addressed soon to prevent further transmission issues.
Driving with a faulty hydraulic pressure sensor can lead to transmission damage and unsafe driving conditions.
• Engine running
• Transmission in operation
The hydraulic pressure sensor is typically located on or near the transmission.
Q: Can I drive with a P0935 code?
A: It's not recommended to drive for long periods with this code, as it can lead to transmission issues.
Q: How can I prevent this code from occurring?
A: Regular maintenance and inspections of the hydraulic system and its sensors can help prevent this code.
