What happens when an EGR solenoid goes bad?
If the EGR solenoid has any issues, it can cause the finely tuned air fuel ratio to be thrown off. This may result in a decreased power, acceleration, fuel economy, as well as an increase in emissions.
How does an EGR valve work on a diesel engine?
When you slowly and efficiently come to a stop, the valve also closes and stops the flow of exhaust gases. The process continues so long as the engine is operating. Once you shut off the engine, the valve also closes and stays in that position. Diesel and gasoline-powered engines can use an array of EGR valve configurations.
What does the canister purge solenoid do in a charcoal engine?
The EVAP system traps this vapor in a charcoal canister and recirculates it for use as fuel for the engine and prevented from polluting the environment. The canister purge solenoid — also referred to as an EVAP canister valve — is responsible for “purging” the EVAP system by acting as the switch that allows the vapor into the engine.

What happens if the canister purge valve fails?
If the canister purge valve fails and sticks open, it will create a vacuum leak that can affect the engine idle speed and quality. A vacuum leak can also be created if the purge solenoid, or any of the hoses that may be attached to it break or become damaged.
