Standard® has Emission Control Covered
Coverage
Comprehensive Coverage
With an ever-growing population and hundred of millions of
vehicles already on the road, service opportunities for ICE and hybrid
emission systems will continue to grow. Standard® offers thousands of
primary and related replacement emission components for import and domestic vehicles.
- Standard® offers components for complete emission system replacement on all five 2019 Ford F-150 powertrains.

Market
Growing Market
It is estimated that the U.S. is responsible for more than 50% of global vehicle emissions. In 2021, the Environmental Protection Agency (EPA) finalized new vehicle emission standards to help further reduce greenhouse gas emissions.
New legislature will have little impact if the vehicles already on the road are not maintained correctly. Keeping vehicle emissions low by maintaining the emission control system with the right components is good business, and good for the planet.
- Since the 1970s, EVAP has been mandated for all gasoline-powered cars and trucks.

System Overview
System Overview
The EVAP system prevents harmful fuel vapors from entering the atmosphere by delivering them into the intake system to be disposed of.
- Fuel vapor is stored in the charcoal-filled fuel vapor canister
- Fresh air is drawn into the canister to keep the system pressurized
- When conditions are right, the purge valve opens, allowing the fuel vapor to be re-burned in the engine

Tech Tips & Impact on Vehicle Systems
As experienced ASE-certified automotive technicians themselves, Standard® Pro Trainers are experts in emission control systems. Here’s what they say to look out for during an emission system service.
After an EVAP system is repaired, it is important to verify the repair by running a self-test and verifying that no DTC has returned (this might not be possible for some small EVAP leak codes).
When a PCV system isn't operating properly, the crankcase of the engine will be under excessive pressure resulting in oil leaks.
A purge solenoid that becomes stuck in the open position will cause the engine to continuously draw fuel vapors from the EVAP system, causing the engine to run rich.
EGR low-flow DTCs can be caused by restricted intake passages, fault control solenoids, and faulty EGR valves.
Always ensure that the control system is operating properly and that the intake passages are free of carbon build up.
While PCV replacement used to be a part of every tune-up, it has been overlooked on many modern vehicles. In some cases, they are incorporated into the valve cover. Always check TSBs and see if there is an updated design available, especially if the engine is experiencing oil leaks.
If an EGR valve is stuck open on a speed-density system which uses a MAP sensor for fuel control, the engine vacuum will be lower and engine load will appear higher, resulting in a rich running condition.
