P0130

Affected Component

Exhaust System

Estimated Time

1-2 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Allow the engine to cool before working on exhaust components to avoid burns.

Symptoms

•Check engine light illuminated
•Poor fuel economy
•Engine rough idle
•Increased emissions
•Failed emissions test

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to confirm P0130.
2
Inspect the wiring and connectors of the upstream oxygen sensor for damage or corrosion.
3
Check the oxygen sensor’s voltage output using a multimeter while the engine is running.
4
Verify the fuel trim readings using a scan tool to assess if they are out of range.
5
Inspect the air intake system for leaks that could affect the oxygen sensor readings.
6
Test the vehicle's battery and charging system to ensure proper voltage supply to the sensor.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

To prevent this issue from occurring again:

•Follow the manufacturer's recommended maintenance schedule
•Address warning signs early before they develop into major issues
•Use quality parts and fluids recommended for your vehicle
•Keep detailed records of all repairs and maintenance

Tools & Equipment Required

•OBD-II scanner
•Oxygen sensor socket or wrench
•Torque wrench
•Multimeter
•Anti-seize compound

Parts Required

•New upstream oxygen sensor (specific to 2020-present Toyota Highlander)

Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working with electrical components.

2. Remove the Old Oxygen Sensor

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

3. Install the New Oxygen Sensor

Apply a small amount of anti-seize compound to the threads of the new oxygen sensor (if not pre-coated).
Carefully screw the new oxygen sensor into the exhaust manifold by hand to avoid cross-threading.
Tighten the sensor to the manufacturer's specified torque (typically around 30 lb-ft, but refer to the service manual for the exact value).
Reconnect the electrical connector to the new oxygen sensor.

4. Reconnect the Battery

Reattach the negative battery terminal.
Ensure all tools and equipment are removed from the engine bay.

5. Clear the Codes and Test

Use the OBD-II scanner to clear the P0130 code from the vehicle's computer.
Start the engine and allow it to reach operating temperature.
Monitor the engine for any abnormal symptoms.
