What is ASM emission 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 is high CO emissions?
too much fuel
High CO means too much fuel. Fuel can only come from three sources: the crankcase vapor control system, the evaporative control system, or the actual fuel delivery system.
How do you read a smog test?
How to Read Smog Test Results
- Review the testing procedure. Using California as an example, vehicles are run through each test at two different speeds.
- Read the first line of the emissions test results.
- Read the results in each emissions category.
- Read and follow any of the maintenance notes included in the report.
How do I lower my HC emissions?
On a precomputer carbureted car, one way to get under the HC and CO limits is to retard the ignition timing. This will slow the idle and provide a longer, hotter burn. Then, bring the idle speed back up to specs with the throttle stop screw or idle stop solenoid, which will admit more air.
Can a dirty air filter cause high CO emissions?
1. Dirty Air Filter – The number one overlooked emissions component, yes, “emissions” component is the engine air filter. A dirty air filter will absolutely restrict air flow, thus disturbing the proper 14.7:1 air/fuel ratio required for optimum fuel combustion.
Is smog the same as emissions?
Smog check, smog test and emission check all refer to the same thing: a test of vehicle and its engine emissions performed at a licensed smog testing facility. Most states require vehicle emissions testing every two years, but not every vehicle requires a smog check.
What does the emission test check for?
Sometimes referred to as smog checks, emissions testing measures the level of pollutants — including hydrocarbons, oxygen, carbon monoxide, and oxides of nitrogen — present in vehicle exhaust. Do I need an emissions test? You likely do. More than 30 states now require some level of testing on registered vehicles.
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 happens if you fail the emissions test?
Think of failing the emissions test as a positive experience rather then a negative one. Where you may have not noticed your vehicle is or was not performing at it’s best and wasting fuel, failing the emissions test will identify this condition and allow you to fix the problem. You will absolutely save money on the long run.
How to read the results from your smog check?
“MAX” indicates the maximum emission allowed for the contaminant, based on your automobile’s model year, engine size and vehicle weight. “AVE” shows the average exhausts produced by cars of the same year, make and model. “MEAS” (which is yellow on the image above) shows the measured emissions from your automobile.
What does Meas stand for on an emissions test?
“MEAS” (which is circled on the image below) indicates the emission results your vehicle produced, and it is the measurement you need to be concerned with in relation to the maximum limits allowed. Measured “MEAS” amounts above the state’s cut-off, or maximum limits, will cause a failure.
