how to fix P0130 code on Toyota Highlander Third Generation (2014-2019)

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Disconnect the negative terminal of the battery to ensure safety while working on the electrical components.

Tools Required:

• OBD-II scanner
• Multimeter
• Socket set
• Torque wrench
• Oxygen sensor socket (if needed)

2. Remove the Faulty Oxygen Sensor

• Locate the upstream oxygen sensor on the exhaust manifold.
• Use a socket or wrench to carefully unscrew the oxygen sensor from its position.
• Disconnect the electrical connector from the oxygen sensor.

3. Inspect and Clean

• Inspect the threads and the mounting area for any debris or carbon buildup; clean if necessary.
• Check the electrical connector for corrosion and clean it with electrical contact cleaner if needed.

4. Install New Oxygen Sensor

• Apply anti-seize compound to the threads of the new oxygen sensor (if not pre-applied).
• Screw the new oxygen sensor into the exhaust manifold by hand to prevent cross-threading, then tighten it with a torque wrench to the manufacturer’s specified torque (typically around 30-40 ft-lbs).
• Reconnect the electrical connector to the new oxygen sensor.

5. Reconnect Battery and Test

• Reconnect the negative terminal of the battery.
• Start the engine and allow it to reach normal operating temperature.
• Use the OBD-II scanner to clear the fault codes and monitor if the P0130 code reappears.
