how to fix B1413 code in Toyota Tacoma N300 (2016-Present)

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative terminal of the battery to ensure safety.
• Allow the vehicle to cool before working on the A/C system.

2. Inspect Wiring and Connectors

• Remove the A/C pressure sensor connector.
• Inspect the connector pins for corrosion, dirt, or damage.
• Clean any corrosion using electrical cleaner and a small brush.
• Reconnect the sensor and check for a secure fit.

3. Replace the Refrigerant Pressure Sensor

• Locate the A/C refrigerant pressure sensor on the A/C line (typically near the condenser).
• Use a wrench to carefully unscrew the old sensor.
• Apply a small amount of thread sealant to the threads of the new sensor.
• Screw in the new sensor and tighten to manufacturer specifications (usually around 15-20 ft-lbs).
• Reconnect the wiring harness to the new sensor.

4. Recharge the A/C System

• Connect the manifold gauge set to the A/C service ports.
• Evacuate the A/C system using a vacuum pump for at least 30 minutes to remove moisture.
• Recharge the system with the correct amount of refrigerant as specified in the owner's manual (usually R-134a).
• Monitor the pressure readings on the gauge set during the recharging process.

5. Test the A/C System

• Reconnect the negative battery terminal.
• Start the engine and turn on the A/C system.
• Monitor the A/C performance and check for any warning lights or codes.
• Ensure the A/C compressor engages and cold air is produced.
