how to fix P0130 O2 sensor code in Toyota Corolla E170 (2013-2019)

Learn how to diagnose and fix P0130 oxygen sensor issues in Toyota Corolla E170 (2013-2019). Step-by-step guide with tools and procedures.

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to ensure safety.
• Raise the vehicle using a jack and secure it with jack stands for better access.

2. Inspect and Replace the Oxygen Sensor

• Tools Required: O2 sensor socket, wrench set, multimeter, jack and jack stands.
• Locate the upstream oxygen sensor located in the exhaust manifold or exhaust pipe before the catalytic converter.
• Disconnect the oxygen sensor wiring harness by pressing the release tab and pulling it apart.
• Using the O2 sensor socket, unscrew and remove the old oxygen sensor from its mount.
• Inspect the threads of the sensor hole for carbon buildup and clean if necessary.

3. Install New Oxygen Sensor

• Apply a small amount of anti-seize compound on the threads of the new oxygen sensor (if not pre-applied).
• Screw in the new oxygen sensor by hand to prevent cross-threading, then tighten it with the O2 sensor socket to the manufacturer's torque specification (typically around 30 lb-ft).
• Reconnect the oxygen sensor wiring harness until it clicks into place.

4. Reconnect Battery and Clear Trouble Codes

• Reconnect the negative battery terminal.
• Use the OBD-II scanner to clear the trouble codes from the vehicle's computer.

5. Test the Vehicle

• Start the engine and allow it to idle.
• Use the OBD-II scanner to monitor the oxygen sensor readings and fuel trim data to ensure proper function.
