What are the exhaust emissions after 2nd fast idle?
– Exhaust emissions carbon monoxide content after 2nd fast idle excessive – Exhaust emissions hydrocarbon content after 2nd fast idle excessive – Exhaust emissions lambda reading after 2nd fast idle outside specified limits The figures on the printout are as follows: 1st idle test – RPM 2750/3150, CO 1.62%, HC 232, Lambda 0.95
Why did my car fail the emission test?
What is CO. My vehicle failed the emission test for high Carbon Monoxides. Why my car produced high CO. High CO failures explained. How can I lower CO. Common high CO failures. Common CO faults. Failed high CO. Failed high Carbon Monoxide.
When to diagnose service engine soon emissions failure?
If the “Service Engine Soon” or “Check Engine” light is on it should be diagnosed prior to any emissions diagnosis. CO Failure is the result of an excessively rich air fuel mixture. The following is a list of the most common causes: HC Failure is the result of incomplete combustion. Any item that causes incomplete combustion can result in high HC.
What causes a high HC reading on an emissions test?
Let’s start by understanding what things cause a high HC reading. A high HC reading means the test found high HC (hydrocarbons) in your emissions. In other words, too much gas is left in the exhaust after combustion.
What is CO. My vehicle failed the emission test for high Carbon Monoxides. Why my car produced high CO. High CO failures explained. How can I lower CO. Common high CO failures. Common CO faults. Failed high CO. Failed high Carbon Monoxide.
What causes a car to have high CO emissions?
A dirty air filter will disturb the normal air / fuel ration and result in less than optimal fuel efficiency, consequently resulting in higher CO emissions. 2. O2 Sensors The computers in your car are hooked up to the Oxygen Sensors.
Where do I Find my Emissions test results?
Toward the bottom of your vehicle’s VIR you will find “ASM Emission Test Results”. This section will indicate the emission results your vehicle produced. “MAX” indicates the maximum emissions allowed for the particular pollutant, based on your vehicle’s year, weight and engine size.
What causes high Co and rich fuel mixtures?
Below are common faults which are likely to produce high Carbon Monoxides (CO) and Rich Fuel Mixtures. Carbon Monoxide is a by-product of incomplete combustion. Carbon Monoxide exceeding maximum limits, can be due to a number of emission failures ranging from inadequate air intake to defective engine computer sensors.
