Passenger vehicles built between 1976 and 1995 will require a test of their fuel evaporative control
(EVAP) system. The test is called the Low-Pressure Fuel Evaporation Test (“LPFET”).
What is the EVAP test for?
The EVAP system is designed to capture fuel vapors (hydrocarbons) from the vehicle. The LPFET is designed to detect
leaks in the EVAP system. EVAP systems can degrade over time and allow smog forming hydrocarbon emissions to
escape into the air, even when the engine is not running. Finding and repairing EVAP leaks will help clean our air by
preventing the release of harmful fuel evaporative emissions from vehicles.
The LPFET will determine if the EVAP system is operating as it was designed by the manufacturer. The Smog Check
technician will use an adaptor in place of the gas cap to connect the EVAP tester to the vehicle and temporarily seal a
vapor line. The EVAP tester will then apply a small amount of pressure to test the system for leaks.
Which vehicles are being tested?
Most vehicles between the model year 1976 and 1995.
What if the vehicle fails the test?
Failing the LPFET will result in the vehicle failing its Smog Check. If a leak is detected, it will have to be repaired.
If your vehicle fails its Smog Check and needs repair, you may be eligible for up to $500 in financial assistance. You also
may be eligible for $1,000 to retire your vehicle through a state approved dismantler. To see if you qualify for either of these
programs, contact the Consumer Assistance Program at 866-272-9642 or check the BAR Web site at
www.smogcheck.ca.gov.
What if the vehicle owner is having trouble finding replacement parts for older vehicles?
If A vehicle owner experiences difficulty finding replacement parts, they should call BAR’s emissions parts locator at (800)
622-7730.
Will there be an additional cost to perform the EVAP test?
Yes, There is an additional cost of $20.00 for this test and it will be added on the work order as part of the estimate.
