Emission Monitors Explained

Buying a used car can be a minefield when it comes to repairs, transparency, and hidden costs. That’s why we offer a premium vehicle inspection service that helps to eliminate any guesswork before you purchase a second-hand vehicle. As a leading provider of pre-purchase inspection in Northern New Jersey, we often get asked about emission monitors and how they work. We’ve created this piece to explain what emission monitors are, why they exist, and how they work.

What are Emission Monitors?

OBD2 Readiness Monitors are fantastic self-check routines that offer expert insight into a vehicle’s diagnostics. The purpose of these monitors is to test the vehicle’s emission control systems. As you can probably guess from the name, emission monitors test and check the performance of your car’s emission-related systems. There are several of these tests that may occur, and having these monitors functioning properly in your vehicle lets you know if these tests are successful.

Types of Readiness Monitors

Readiness monitors can either be continuous or non-continuous. While continuous monitors are always going as long as your car is turned on, non-continuous monitors can only complete tests under specific conditions. Some of these conditions are reliant upon drive cycles, as the car needs to warm up and cool down in between each test. Ultimately, the conditions really come down to your individual emissions monitor your car is equipped with.

Monitor Status Readings

When you run a test with your readiness monitor, you will be able to see the status of said test through the output status. The following three statuses are what you may see when checking the status of your test:

The following infographic should illustrate to you what signs to look for when viewing your emissions readings.
