Frequent P0410 OBD2. (PAIR) Air pump run ok if relay manually
opperated.. Have also changed realy.. ECU fail to energise it... (ECU Energises Vacume soleniod okay sas valve opens)
Vacume soleniod operates ok and opens sas valve.
I am completely in the dark now.
Can the O2 sensors contribut to this dilema.?
Any Advice would be greatly Appreciated..
