Lack of power and engine management light on, fault code stored P0400. EGR system flow malfunction.
New EGR valve was fitted at Toyota dealer but fault still present.
The fault was cured by cleaning the intake system with Forté Diesel Intake Cleaner as per instructions. Forté Clean and Protect was carried out and Forté Advanced Formula Diesel Treatment was added to the fuel tank and a 50 mile road test was carried out.
After treatment the fault code cleared and the vehicle performance was restored.
Forté's Technical Helpline receives over 300 calls per month. This blog shares solutions for garage workshops on common driveability concerns that can be quickly and effectively treated. The vast majority of those identified are caused by fuel and oil borne contamination formed by natural degradation or via the combustion process. This is a fact of life for internal combustion engines where fossil fuels and oils are used.
