I’ve got two injectors that I’m doing some electrical checks on. From the part numbers, I believe they fit the V40 D2.
The interesting thing is that they have 6 pins rather than the usual 2.
I’m trying to find out 2 things:

1. Which pins actuate the injector?
2. Are these injectors a solenoid type or a piezo stack type?

thanks for any info.

Ive limited knowledge on this, but was told only the D4 has the piezo type... Im sure one of the more technically minded will be along soon:unsure:

Many thanks; that’s very helpful. I phoned Denso today and was told there was a pressure sensor and possibly a temp sensor inside, so that would account for the other 4 pins. And he wasn’t sure if it was solenoid or piezo. As I had measured 0.7Ω across the left end pair of pins, I was happy enough to take it as a solenoid type. Your answer has boosted that confidence.
