Electric EGR control valve component resistance | Electric EGR control valve operating Hz | Electric EGR control valve operating duty |
14.7 ~ 16.1Ω (20℃) | 142Hz | 5%(closed)~39%(opened) |
Fig.1) Approx. 5% duty signal waveform of Electric EGR control valve (with EEGR valve closed)
Fig.2) Approx. 57% duty signal waveform of Electric EGR control valve(with EEGR valve opened)
The output of approx. 5% duty is mainly for the diagnosis of Electric EGR control valve circuit than actuating EEGR.
