Laymans terms

The car's computer is having trouble getting a steady signal from a sensor that checks the pressure in the hydraulic system, which helps the car shift gears.

Explanation

The powertrain control module (PCM) detects an inconsistent signal from the hydraulic pressure sensor, which is crucial for monitoring the transmission's hydraulic pressure.

Technical description

The P0936 code is triggered when the PCM detects an intermittent or erratic signal from the hydraulic pressure sensor circuit. This sensor is responsible for providing real-time data on the hydraulic pressure within the transmission, which is essential for optimal shifting and transmission performance.

Symptoms

• Erratic or harsh shifting

• Transmission slipping

• Check Engine Light illuminated

Common Causes

• Faulty hydraulic pressure sensor

• Damaged or corroded wiring/connectors

• Faulty PCM

Glossary

OBD-II: On-Board Diagnostics, Second Generation

Diagnosis steps

• Use an OBD-II scanner to confirm the code.

• Inspect the wiring and connectors for damage or corrosion.

• Test the hydraulic pressure sensor for proper operation.

Repair procedures

• Replace the hydraulic pressure sensor if faulty.

• Repair or replace damaged wiring/connectors.

• Reprogram or replace the PCM if necessary.

Tools required

• OBD-II scanner

• Multimeter

• Basic hand tools
