Additionally, the 3.5 EcoBoost may generate the P0016 fault code, which will illuminate the check engine light. My thinking is at low absolute loads the target fuel pressure is relatively low so the PCM is looking at the low range sensor, however this is at a constant 5 volts (no pressure conversion on my scan tool) which sounds like top scale, so the PCM thinks it needs to shorten the injector pulse width. Each of the wires on the HP fuel rail sensor were back probed in turn and with the multi meter set to ohms the loom damage area was probed with the other lead.
