What to Do When the Fuel Tank Ventilation System Throughput is Incorrect?
2 Answers
Incorrect throughput in the fuel tank ventilation system is generally caused by blockage in the activated carbon canister or the carbon canister solenoid valve. Below is relevant information about the exhaust system: 1. Definition: The exhaust system refers to the system that collects and discharges waste gases, including the exhaust manifold, exhaust pipe, muffler, tailpipe, and resonator. 2. Main chemical components and functions of the exhaust system catalyst: The catalyst mainly contains precious metal elements such as platinum, rhodium, and palladium. Platinum controls CO emissions; rhodium controls NO emissions; palladium controls HC emissions. After the exhaust manifold, a catalytic converter is connected to convert incompletely burned pollutants into harmless substances, protecting the environment.
Last time I encountered an issue with poor ventilation in the fuel tank exhaust system, and I kept smelling gasoline while driving, which was quite annoying. At first, I thought the fuel cap wasn't tightened properly, but after checking, it was fine. I asked some car-savvy friends, and they suggested it might be a clogged exhaust valve or a leak in the tubing, which could cause the car to run poorly or even trigger the check engine light. I quickly drove to a nearby repair shop, where they used diagnostic tools to check the error codes, and sure enough, it showed an issue with the EVAP system. The mechanic suggested cleaning the valve first, and if that didn’t work, replacing the part. It cost a few hundred to fix. After that, I started regularly checking the fuel cap and tubing connections to avoid dust blockages, realizing that good car maintenance habits are important to avoid unexpected issues that could ruin the driving experience. In short, if you notice any abnormalities, don’t delay—get it checked and repaired promptly, as safety comes first.
