Toyota is a leading automotive brand that is known for producing high-quality vehicles that are both reliable and efficient. One of the key components of Toyota’s emissions control system is the NOx sensor, which is designed to measure the amount of nitrogen oxide (NOx) that is being emitted by the vehicle. Here is an article to prompt Toyota NOx Sensor, including its function, OE number, and replacement key points.

Function of Toyota NOx Sensor

The NOx sensor in a Toyota vehicle plays an important role in reducing the emission of nitrogen oxides, which are harmful pollutants that contribute to smog and air pollution. The NOx sensor measures the levels of nitrogen oxide in the exhaust system and sends this information to the engine control unit (ECU). The ECU then adjusts the engine’s air-fuel ratio to ensure that the vehicle is emitting the minimum amount of pollutants.

OE Number of Toyota NOx Sensor

If you need to replace the NOx sensor in your Toyota vehicle, it is important to use the correct OE (Original Equipment) number to ensure compatibility with your vehicle. Here are some common OE numbers for Toyota NOx sensors:

  1. Toyota Corolla: OE number 89467-12010
  2. Toyota Camry: OE number 89467-33080
  3. Toyota RAV4: OE number 89467-42020
  4. Toyota Prius: OE number 89467-47020
  5. Toyota Tacoma: OE number 89467-04090
  6. Toyota Tundra: OE number 89467-0C020

It is important to check your vehicle’s manual or consult with a qualified Toyota technician to confirm the correct OE number for your specific make and model.

Replacement Key Points for Toyota NOx Sensor

Replacing the NOx sensor in your Toyota vehicle can be a relatively simple process if you follow these key points:

  1. Ensure that the engine is completely cool before beginning the replacement process.
  2. Locate the NOx sensor in your vehicle’s exhaust system. It is typically located near the catalytic converter.
  3. Disconnect the wiring harness from the NOx sensor.
  4. Remove the sensor using the appropriate tools.
  5. Install the new NOx sensor using the correct OE number and tighten it to the manufacturer’s specifications.
  6. Reconnect the wiring harness to the new sensor.
  7. Clear any error codes from the ECU using a diagnostic tool.
  8. Start the engine and check for proper sensor operation.

In conclusion, the NOx sensor is an important component of Toyota’s emissions control system, and it is crucial to ensure that it is functioning properly to reduce the vehicle’s impact on the environment. By using the correct OE number and following the key replacement points, you can easily replace your Toyota NOx sensor and keep your vehicle running smoothly and efficiently.
