Isuzu Oxygen Sensor Customer Reviews

Works great ty đź‘Ťđź‘Ť

Oxygen Sensor - Sold Individually
Jun 12, 2020
Very happy with purchase!
Perfect fit and even had a about 4-6 inches of extra cable that I just looped and secured with a ty-wrap. You'll definitely want to use the 22mm crowfoot when removing and installing the sensor-way easy for working between the engine block and firewall. More importantly, the code didn't come back (P0135).

Isuzu Oxygen Sensor Articles

The Isuzu oxygen sensor is a tiny vehicle component that helps in the regulation of the fuel and air ratio of the engine. To perform at its best, the engine needs a precise balance of fuel and air delivered to the engine cylinders for combustion. This mixture, if balanced correctly, will provide a clean burn of fuel, which in turn provides efficient engine performance and power. The Isuzu oxygen sensor helps in this process, monitoring the amount of oxygen left in the exhaust emissions expelled from the engine after each combustion cycle to determine if the fuel has burned as efficiently as it should. Producing voltage with a chemical reaction, the Isuzu oxygen sensor sends a signal with this voltage to the vehicle computer from its position in the exhaust system of the vehicle, transmitting the level of oxygen present in the exhaust. The computer uses this information from the Isuzu oxygen sensor to determine the amount of adjustment that is necessary in the fuel and air ratio to optimize the performance of the engine. This constant cycle of monitoring and adjustment is necessary due to the changing levels of oxygen concentration in the air. The oxygen level present in the air changes with many factors, such as elevation, air temperature, and the load placed on the engine, among many other variables. The proper function of the Isuzu oxygen sensor makes it possible for your engine to compensate for these changing conditions. Our online catalog carries a selection of quality Isuzu oxygen sensor replacements at very affordable prices. Our secure site will make ordering your Isuzu oxygen sensor fast and easy or our toll-free phone line is available for your convenience.

Isuzu Oxygen Sensor Buyer’s Guide

Summary:

  • The oxygen sensor, or O2 sensor, measures the amount of oxygen in the exhaust as it exits the engine. The information it sends to your engine’s computer helps keep the engine running efficiently.
  • Oxygen sensors are built to last for a long time, but it’s still important to check on them every now and then, especially if you have 100,000 miles or more on your odometer.
  • Original Equipment Manufacturer (OEM) Isuzu O2 sensors are those produced by Isuzu or any of their official suppliers. Original Equipment (OE) replacement O2 sensors, on the other hand, are oxygen sensors produced by any other car parts manufacturer not affiliated with Isuzu.
  • Both OEM and OE replacement sensors are designed to fit and perform the same way as the original sensors.
  • A replacement oxygen sensor for your Isuzu vehicle can cost anywhere between $15 and $200.

Japanese automaker Isuzu Motors is well-known for their commercial vehicles and diesel engines. Over the years, Isuzu also sold a number of light passenger vehicles in North America such as the Isuzu Rodeo, Hombre, and Ascender. Now, however, Isuzu only sells their SUVs and pickup trucks in Asia.

Although Isuzu light vehicles aren’t sold in North America anymore, their commercial trucks continue to dominate the market. This means that the demand for Isuzu truck parts continues to increase. One of the important parts of Isuzu trucks that will need to be replaced after a while is the Isuzu oxygen sensor.

What is an Oxygen Sensor and What Does It Do?

The oxygen sensor, also called the O2 sensor, measures the amount of oxygen present in the exhaust as it exits the engine. It’s a critical component of your vehicle’s exhaust system because the information it sends to your engine’s computer helps it determine how much fuel is needed to keep the engine running as efficiently as possible.

All vehicles manufactured from 1981 onwards are required to have an oxygen sensor. Depending on your truck’s model and year, your Isuzu can have as many as five oxygen sensors, sometimes even more.

What Happens When the O2 Sensor Fails?

It’s safe to drive your vehicle even with a bad O2 sensor. You won’t have stalling issues or immediate safety problems when one or more of the oxygen sensors fail. However, your vehicle won’t run efficiently until the sensor is replaced. To maximize fuel economy and keep your engine in perfect condition, have a faulty O2 sensor replaced as soon as possible.

Oxygen sensors are built to last for a long time, but it’s still important to check on them every now and then, especially if you have 100,000 miles or more on your odometer.

OEM vs OE Replacement Isuzu Oxygen Sensor

Original Equipment Manufacturer (OEM) O2 sensors are those produced by Isuzu or any of their official suppliers. Original Equipment (OE) replacement O2 sensors, on the other hand, are oxygen sensors produced by any other car parts manufacturer not affiliated with Isuzu.

Both OEM and OE replacement sensors are designed to fit and perform the same way as the original sensors. For instance, an OE replacement Isuzu Rodeo oxygen sensor is designed to match the exact specifications of the factory-issued Rodeo O2 sensor in terms of both size and performance.

If you’re buying an OE replacement sensor, it’s important to know the exact location of the damaged sensor to ensure that the replacement part you’re getting will fit properly.

Universal Oxygen Sensors

Another popular option for oxygen sensor replacement is a universal oxygen sensor. Universal oxygen sensors are designed to fit practically any vehicle with some tweaking. Since a universal O2 sensor doesn’t have a direct-fit connector, you will need to splice some wires to install one.

Oxygen Sensor Replacement Cost

A replacement oxygen sensor for your Isuzu vehicle can cost anywhere between $15 and $200. Generally, universal oxygen sensors have slightly lower prices compared to direct-fit OE replacement O2 sensors.
