What to know about 1990 Acura Integra O2 Sensor?

The 1990 Acura Integra has a single oxygen sensor, which is located before the catalytic converter. The oxygen sensor monitors the amount of oxygen in the exhaust gas and sends this information to the engine computer. The engine computer uses this information to adjust the air-fuel ratio to ensure optimal engine performance and emissions control.

A faulty oxygen sensor can cause a number of problems, including:

  • Reduced fuel economy
  • Increased emissions
  • Poor engine performance
  • Illuminated check engine light

If you notice any of these problems, it is important to have your oxygen sensor checked by a qualified technician.

Here are some things to know about the 1990 Acura Integra oxygen sensor:

  • It is a heated oxygen sensor, which means that it has a heating element that helps it to reach operating temperature more quickly. This is important because the oxygen sensor does not work properly until it is up to temperature.
  • The oxygen sensor has a lifespan of around 50,000 to 100,000 miles. However, it may need to be replaced sooner if it is exposed to excessive heat or if the engine is running rich.
  • The oxygen sensor is a relatively inexpensive part, and it is relatively easy to replace.

If you need to replace the oxygen sensor in your 1990 Acura Integra, it is important to use a high-quality sensor. There are many cheap aftermarket sensors available, but they may not last as long as a genuine Acura sensor.

Here are some tips for maintaining the oxygen sensor in your 1990 Acura Integra:

  • Replace the air filter regularly.
  • Avoid using fuel additives.
  • Have the car’s engine tuned regularly.
  • Fix any exhaust leaks.
