How to Deal with Ford Exhaust Gas Recirculation System Flow Fault?

Here are the specific solutions for Ford exhaust gas recirculation system flow faults: 1. For Ford EGR valve troubleshooting, fresh air must continuously circulate in the crankcase to reduce the operating temperature inside the crankcase and dilute the exhaust gases that have entered. 2. If the recirculated gas is discharged into the atmosphere, it will cause environmental pollution and energy waste. Therefore, the engine is equipped with a crankcase ventilation valve and a PCV valve, connecting the PCV valve, crankcase, and intake manifold together. The pressure regulating valve inside the PCV valve can act as a throttle based on the pressure difference between the crankcase and the intake manifold.

I personally encountered an EGR flow fault in my Ford, which essentially means there was an issue with the exhaust gas recirculation system. Common causes include a stuck valve, carbon buildup blocking the pipes, or sensor false alarms. You should start with the basics: open the engine hood and check if the EGR valve is clean. If it's sticky, try spraying some cleaner on it; if that doesn’t work, remove and clean it or replace it entirely. Regularly using high-quality engine oil and fuel can help prevent carbon buildup. This fault can lead to increased emissions and reduced power, so don’t delay—fixing it promptly saves fuel and hassle. After repairs, just clear the fault code. I dealt with this last week, applied anti-rust spray to prevent corrosion, and the car runs much smoother now.

I find EGR system flow faults quite annoying, especially in Ford models. It's mostly caused by a clogged exhaust valve or faulty sensor giving inaccurate signals. I've noticed this triggers the check engine light and may affect emission tests during annual inspections. My suggestion is not to rush into DIY repairs - first use a diagnostic tool to read the trouble codes and pinpoint the issue; if unavailable, scan with an OBD tool. For safety, taking it to a professional repair shop is most reliable as they have the expertise to avoid damaging other components. Regular highway driving helps burn off carbon deposits to prevent clogging. If the valve is faulty, replacing it only costs a few hundred bucks - worth addressing promptly to avoid roadside breakdowns.
