Small leak from EGR solenoid during smoke test Hey all, just wanted to communicate something that we found last night. Then the EGR valve will not respond to commands and the built in spring mechanism will close the. the medium/heavy composite vehicle control system is based on designs common to many engine and vehicle manufacturers. For example, the system is operable to determine a number of EGR system-related fault and failure conditions by monitoring measured and command EGR position signals to determine EGR valve controller functionality, to monitor response times between fully open and closed EGR valve positions by comparing measured response times to a calibratable response time value, and to monitor in-range EGR position failures associated with fully closed and fully opened EGR valve position values. This dilutes the O2 in the incoming air stream and provides gases inert to combustion to act as absorbents of combustion heat to reduce peak in-cylinder temperatures. Wynn's Injector Cleaner for Diesel Engines is a treatment, which increases engine performance, reduces black smoke and improves MPG. You could also run the output tests in vagcom and watch the EGR valve move. Smoke testing is the best way to test the EVAP system. The EGR valve therefore helps maintain the exhaust system at full capacity and increases the longevity of the internal combustion process. Vacuum pressure is manually applied to the EGR valve with a pump and a slight stumble is noticed. connect a vacuum pump to the EGR Valve or see the EGR test jig drawing below. If you don't see it, search for your EGR valve online by going to an auto parts store website and entering your car's make, model and engine size to look for the valve. Hello everyone! I recently did a smoke test on my 97 Honda civic and I came across the body of the EGR valve leaking smoke. fitted a new egr and it fixed the. However, it's difficult to source where I live (nearest Shell 35 miles away) so really just used supermarket fuel but this is the result.
