The Detection pump is a key element in modern cars, used to detect leaks in the fuel evaporation control system. It creates pressure or vacuum in the system and then checks whether that pressure is maintained. If a leak is detected, the pump transmits a corresponding signal to the vehicle’s on-board computer. Replacing the detection pump is necessary to eliminate fuel vapor leaks, help maintain the effectiveness of the evaporative control system and help reduce harmful emissions into the atmosphere.
When it comes to our vehicles, we all want them to run smoothly. But sometimes, pesky problems like Evap system leaks can throw us off track. This type of issue typically leaves trails, such as a fuel smell.
An Evap leak is when your vehicle's Evaporative Emission Control system, which is responsible for keeping fuel vapors in check, develops a minor breach. So instead of those vapors staying where they should, they sneak into the air.
Paying attention to the signs and taking action can save you some headaches and money in the long run. So, if you catch a whiff of gasoline or that "Check Engine" light starts acting up, don't brush it off. Your Evap system might just be trying to get your attention.
