Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shocks.
Ensure you have proper personal protective equipment (PPE) such as gloves and safety glasses.

2. Recover Refrigerant

Tools Required: Refrigerant recovery machine.
Connect the recovery machine to the A/C service ports.
Follow the machine’s instructions to recover the refrigerant safely.

3. Replace A/C Pressure Sensor

Tools Required: Socket set, torque wrench, wiring harness connector.
Locate the A/C pressure sensor on the A/C line.
Disconnect the electrical connector from the sensor.
Remove the sensor using the appropriate socket and torque specifications (usually around 15-20 Nm).
Install the new A/C pressure sensor, ensuring it is seated properly and tighten to specification.
Reconnect the electrical connector.

4. Recharge A/C System

Tools Required: A/C manifold gauge set.
Connect the manifold gauges to the A/C service ports (high and low).
Follow the manufacturer’s recommended procedure to recharge the system with the correct type and amount of refrigerant.

5. Finalize and Test

Reconnect the vehicle battery.
Start the engine and activate the A/C system.
Monitor the A/C performance and check for the presence of the B10C1 error code.
