What is a vapor canister purge solenoid?
The canister purge valve is a vital part of the Evaporative Emission Control System (EVAP). The EVAP system seals the fuel system of your vehicle to prevent harmful fuel vapors from entering the environment. In newer model vehicles the purge valve is electrically operated solenoid controlled by the engine computer.
How does a vapor canister purge valve work?
The EVAP system prevents fuel vapors in the fuel tank from escaping into the atmosphere. When the engine is running under certain conditions, the fuel vapors are purged from the canister and burned inside the engine. The purge valve precisely controls the amount of fuel vapor that is purged from the charcoal canister.
Where is the purge canister purge solenoid located?
The solenoid for the purge vent valve is located near the vapor recovery carbon canister, a diagram of the location of the carbon canister is located under the hood on the emission sticker. 01 camry code po441…start with gascap? This indicates that a part of the EVAP control system is no longer fuctioning correctly.
How does the vapor canister purge valve work?
The Evaporative Emission Control system features a vapor canister purge valve which manages the quantity of fuel vapor coming out of the charcoal canister. The purge valve used to be controlled with a vacuum but now, newer cars allow the engine control unit to electronically control it.
When does canister purging occur in an engine?
Therefore, canister purging occurs when the intake manifold pressure is below atmospheric pressure, such as when the engine is idling. The flow of vapor from the canister to the intake manifold is regulated by the ECM-controlled purge control valve.
How does duty cycle EVAP canister purge solenoid ( DCP ) work?
The duty cycle EVAP canister purge solenoid (DCP) regulates the rate of vapor flow from the EVAP canister to the intake manifold. The Powertrain Control Module (PCM) operates the solenoid. During the cold start warm-up period and the hot start time delay, the PCM does not energize the solenoid.
Where is the purge control solenoid valve located?
The Purge Control Solenoid Valve (PCSV) is installed in the passage connecting the canister to the intake manifold. It is a duty type solenoid valve and is operated by ECM/PCM signal. To draw the absorbed vapor into the intake manifold, the ECM/PCM will open the PCSV, otherwise the passage remains closed.
Is the canister purge valve part of the EVAP system?
The canister purge valve, also commonly referred to as the purge valve, is an important component of your Evaporative Emission Control (EVAP) system.
What happens when a canister purge valve goes bad?
When a component in this system, like the canister purge valve (also known as a purge valve solenoid), goes bad, it can cause rough idling, a Check Engine light, or difficulty starting your vehicle. It is best to fix an EVAP system leak as soon as you notice there is a problem.
