What do they look for in an emissions test?
These tests measure the amount of tailpipe emissions produced by car engines, in order to check whether a vehicle meets the regulations that restrict emissions of specific pollutants. They measure levels of nitrogen oxide (NOx), carbon monoxide (CO), particulate matter (PM), non-methane organic gases (NMOG), and formaldehyde (HCHO).
What causes a car to have high hydrocarbon emissions?
Below are common failures which are likely to produce high Hydrocarbon HC. Hydrocarbons are basically raw fuel, otherwise known as Gasoline. High Hydrocarbon (HC) emissions are almost always a sign of poor fuel ignition. However, it’s not always that the engine’s ignition system is responsible for high Hydrocarbon emissions.
Why is it important to have tailpipe emissions test?
Given that motor vehicles are among the leading sources of air pollution, keeping tailpipe emissions at bay is crucial for improving air quality and reducing negative environmental impact.
A couple of weeks ago I changed my battery but had not driven the car much before taking it to inspection and promptly failed the emission test because the evaporative, catalyst and O2 systems were not ready. Since then I drove about 100 miles with a mixture of local roads and highway over a 4 day period.

4) get into the car, take it for a drive of various speeds, starting at 25 mph for about 1-5 miles….as time goes on, increase your speed to the LEGAL SPEED LIMITS on your roads…DO NOT SPEED. If you can, THEN get on the highway, and go the SPEED LIMIT for about 5-10 miles….
What happens when you change the battery on a car?
Replacing the battery or even simply disconnected the battery on a vehicle will cause the engine control unit (ECU) to reset and clear all the emission monitors (and trouble codes; if any existed). Emission monitors are needed to be READY or COMPLETE in order for the vehicle to pass the smog check.
Can a car pass a smog test after battery was changed?
I was told it could not pass a smog test until the computer was reset; at a cost of $135.00.This car has always past before. What difference would this make if they are sticking the tester in the exhaust pipe?

Can a defective O2 sensor cause carbon monoxide?
A defective O2 sensor will cause increased carbon monoxide emissions. More about oxygen sensors. 3. Defective Manifold Absolute Pressure (MAP) Sensor – The MAP sensor determines the level of vacuum created during an engine’s intake stroke, and sends this information to the ECU.
What causes low engine temperature and high co?
Defective Engine Coolant Temperature (ECT) Sensor – Low engine temperature requires more fuel. When the ECU is unable to determine what the engine’s accurate temperature is, it will not adjust fuel delivery properly; resulting in high CO.
What is the trouble code on my Toyota Camry?
P0442 Toyota Camry. October 13, 2018. A very common trouble code with the Toyota Camry is P0442 . This code references a number that is given to you when you plug your vehicle into a OBDII scanner, and has to do with the emissions system.
How does the EVAP system work on a Toyota Camry?
