Are you experiencing emission system problems in your Honda? If yes, then you are at the right place to know the cause of this issue and how you can fix it. 

An Emission System Problem is one of the most common issues encountered by Honda Pilot owners. According to reports, Honda has yet to address its problem successfully, but most dealers have stated that this difficulty arises around 40k to 60k miles and sometimes even earlier. 

Though the Technical Service Bulletin (TBS) released by Honda in 2020 noted that the warranty of Honda emissions is extended for ten years from the date of purchase or to around 150k miles of travel, there is information produced on which dealers identify this issue and to fix it. 

What Are The Emissions System Problems in Honda?

Emission system problems in Honda arise primarily due to faulty fuel injectors, which are the cause of various errors in the emission system. These include;

  • The engine vibrates more than often, and the car shakes at spotlights or in traffic.
  • Your automobile delivers a poor fuel economy due to a drop in the MPG levels.
  • The Check Engine warning light is produced frequently, asking you for a call-to-action.

The catalytic converter filters the emissions from the air, and as a result, excessive emissions will cause the catalytic converters to wear out quickly.

In addition, if the oxygen sensor on the exhaust is defective, you may observe that your car uses more fuel. Moreover, reports of EGR valve failure and loose gas caps are also reasons for problems in the emission system. 

5 Steps to Fix Your Problem with The Honda Emissions System

Fix your Honda Pilot Emission System problem by using this five-step guide. This step-by-step check ensures that you reach all the potential sources from which issues can arise, which further cause difficulty to the emission system.

Check The Air Filter Cleaning System

The air filter is an essential part of the cleaning system. It filters dust, dirt, and foreign particles from getting into the system. However, if the air filter is clogged or has been covered with grime, it must be cleaned to ensure its smooth usage. 

Examine The PCV Valve

The PCV valve or the Positive Crankcase Ventilation feeds gases from the crankcase to ensure the engine is free from sludge formation and air pollution. However, damaged or clogged PCV systems can also cause problems in the emission system. 

Utilize The EVAP System

The Evaporative Emissions Control System, or EVAP, ensures that toxic fuel vapors are not released into the atmosphere. But damages in its parts, including the canisters and hoses, can also cause the issue. 

Inspect The EGR System 

The Exhaust Gas Recirculation or EGR system reduces the harmful emission of gases such as nitrogen dioxide formed during combustion. Blacked pipelines and damage to this system also caused the emission system problem in Honda.

Maintain The Air Injection System

The air injection system of the car uses catalytic converters to reduce the carbon monoxide and hydrocarbons produced during the combustion process. And damages to this system should be repaired quickly.

Some may find a solution to their problem in the second step, while others may find it in the final step. Though the range and issue of each automobile may differ, these five steps will help you identify and fix the problem.
