Re: Can anyone tell me what this part is??
Yes, it's a PWM (pulse-width-modulated) EGR solenoid. The 'puter pulses the solenoid x times per second. The larger the X, the more "open" the EGR valve is...
In other words, this allows the EGR to be partially open if required (instead of just completely open or completely closed). I wish I knew more about how the computer does it but I don't...
