Hi, thanks for reading this post
Quick background: I recently bought a Zafira Z22YH Auto and I'm planning to DIY the thing into shape ... i have a 'Projects' thread here about the car
The single biggest issue I have is that the car is in limp mode cos of a fuel pressure issue.
I've been waiting to get an OpCom device to follow the recommended procedure for finding whether the fuel pressure regulator or the high pressure fuel pump is the problem.
So I finally hooked everything up today and I am getting values something that are inconsistent with any info I have seen thus far, which is why I posted a new thread, and here's what I see:
- My fuel pressure feedback value is exactly 380kpa, regardless of throttle position.
- When I follow the recommended procedure and disconnect the Fuel Pressure regulator, i get a fuel pressure feedback voltage of exactly 0.6V regardless of throttle position
- When I plug the fuel pressure regulator back in, i still get exactly 380kpa and 0.6V in all conditions... idle, full throttle and everything in between
So ... I'm very aware that this doesn't necessarily tell me whether my high-pressure fuel pump and/or fuel regulator are ok, BUT is this a clear sign that my fuel pressure sensor is dead?
