Hi there , hope you can help ! I have a problem with a caravelle 2.5 TDi engine code ACV.fault with needle lift sensor implausible signal .Engine won’t rev without stuttering.checked fuel delivery,no air in pipes ,changed filter still the same went on guided component tests and no info for this particular engine code so went into another year and info was that both wires are signal .but I have battery voltage to pin 1 pin 2 is Showing a connection to ecu so I don’t suspect wiring . The sensor reads 91 ohms across terminals I have been told this is ok tried scoping it and no waveform .does anyone have any info please ..regards Ian
