How do I choose the right oxygen sensor?

How do I choose the right oxygen sensor?

The number and location of the oxygen sensors are specific to every vehicle’s year, make and model. The location of the oxygen sensor is usually identified by position (sensor 1, sensor 2) and by cylinder bank (bank 1, bank 2). Bank 1 is the side of the engine where cylinder #1 is located. Bank 2 is opposite to Bank 1.

Do O2 sensors need anti-seize?

Most oxygen sensors come with a special electrically conductive anti-seize compound applied to the threads, so it’s merely a matter of threading the new sensor into the void left by the old one.

Are aftermarket oxygen sensors any good?

It’s true that you may find an aftermarket oxygen sensor that’s advertised as better than OEM. There’s still no guarantee that it’ll outperform an OEM oxygen sensor when it comes to working with your ECU and withstanding the continuous exposure to hot exhaust.

Can you use aftermarket O2 sensors?

Should I use OEM oxygen sensor?

OEM Oxygen Sensors are Cheaper in the Long Run If an aftermarket oxygen sensor fails prematurely, you have no choice but to buy a new one. The costs can add up over time. All in all, OEM is a safer bet than aftermarket when it comes to oxygen sensors.

Why choose Denso oxygen sensors?

In head-to-head testing against the leading competitors, DENSO oxygen sensors were rated two times more resistant to silicone and lead poisoning. At DENSO, we bring together everything we know as an OE supplier to provide aftermarket oxygen sensors that truly are Better By Design™. Any good mechanic will tell you use the very best products you can.

What is a light duty oxygen sensor?

DENSO’s Light Duty oxygen sensor started to appear on vehicles with the development of fuel injection systems. The basic job of the sensor is to monitor the air fuel mixture under idle, moderate acceleration and cruise conditions.

How do I choose the right oxygen sensor for my vehicle?

Most vehicles have multiple oxygen sensors. Understanding the location terminology in catalog data and diagnostic tools is important to choosing the correct sensor. Catalog data may contain additional vehicle criteria that requires careful selection.

What happens to the oxygen sensor under heavy acceleration?

Under heavy acceleration the oxygen sensor goes into “open loop”, which basically means that the engine management computer system ignores the oxygen sensor. Oxygen sensors have a smaller range of limits in detecting and adjusting the difference from an optimum air/fuel ratio.
