How Much Does an EVAP Smoke Test Cost?
The Evaporative Emission Control (EVAP) system is designed to store and dispose of the fuel vapor built up in the fuel system of a vehicle, preventing the vapor from escaping into the atmosphere.
Abnormalities in the EVAP system may lead to driving problems and can mean failure on the two-speed idle test or enhanced I/M evaporative pressure or purge test. EVAP smoke testers are used to check the system for leaks that affect the performance of a vehicle. EVAP smoke tests can be done via different methods.
How much does it cost?
- The test itself is going to cost an average of $60 to as much as $150. This is just for the test and won’t cover the repairs.
- According to SmogTest.com, the average cost to repair an EVAP system that failed the EVAP test is $250.
- A diagnostic smoke test, according to British Columbia-based Jericho Electronics, costs $89.99 at some shops. The price does not include repair.
- For those who want to purchase the machine that can provide the test, the costs are going to be an average of $1,200 to as much as $2,000. Average machines are good for up to 500 tests.
- The Vacutec Evaporative System Tester Smoke Machine at ReStockIt.com costs $1,651.34. The system comes with a built-in compressor and is user refillable. Each refill is good for 500 tests.
What is going to be included?
- The purpose of the EVAP system is to reduce the amount of fuel vapors escaping into the atmosphere and maintain the efficiency of a vehicle. The fuel vapors in the EVAP system are typically stored in a charcoal canister and flushed out and burned in the combustion chamber during different states of operation. Tests are conducted to ensure that the EVAP system is working efficiently. If a test yields results that go beyond preset parameters or limits, a DTC (Diagnostic Trouble Code) is set and causes a MIL (Malfunction Indicator Light) or SES (Service Engine Soon) warning that alerts the driver of a malfunction.
- Leaks usually found in automobiles include broken or disconnected vacuum lines, broken exhaust, damaged throttle shafts as well as cracked plastic components and leaking gaskets and fittings, to name a few. By having EVAP smoke testing, leaks are found and subsequently repaired, keeping the vehicle in good condition.
- An EVAP smoke test procedure usually entails a technician clamping the end of the EVAP hose that leads to the charcoal canister and applies pressure on the gas tank using Nitrogen through the EVAP test device. The tool calculates the drop in pressure resulting from leaks. If there is a loss of pressure, the vehicle will fail the EVAP portion of a smog test. Vehicles that fail the EVAP smoke test the first time are usually subjected to Phase Two of the process, which signifies that a leak large enough to set a DTC is detected.
What are the extra costs?
- An airlift cooling system leak checker and purge tool kit may be a necessary extra purchase. The tool, which can cost about $100, eliminates problematic airlocks in modern automobile cooling systems.
- For do-it-yourselfers, specific tools may also be required to perform the task efficiently. These may include hose clamp pliers, a hose removal tool, a spill-free funnel, to name some. The items can range in price from $20 to $40 each.
- If repairs are required after a test, costs can be as high as $1,000, depending on the job that has to be done.
Tips to know:
- Industry experts estimate that of the 7 million vehicles that need to undergo an EVAP smoke test each year, 11% of them will fail.
- Avoid emissions failure due to normal evaporative emissions purge cycle. Do not test the vehicle following extended hot soak periods, prolonged idle, or after it has been left sitting out in the sun in hot weather. These conditions result in the accumulation of copious amounts of fuel vapor in the charcoal canister.
- There are scan tools that have bi-directional controls with the ability to command the vehicle to conduct a self-test of the EVAP system. The test can take 10 to 20 minutes and is regarded as more comprehensive than the initial testing procedure for the reason that all the components of the system are tested.
How can I save money?
- Professional services can be obtained at service centers. Check with different local outlets to find out the rates offered for an EVAP smoke test. Before making a choice, be sure to ask previous clients about their experience with the service provider.
- If you are planning to buy your own EVAP smoke test kit, make sure to perform comparison shopping steps to find the most cost-effective machine being made available in the market.
- Find suppliers that offer free shipping to avoid freight charges. Check the requirements that need to be satisfied in order to obtain the free shipping offer.
