Could anybody supply me with a waveform of the injector needle lift sensor or tell me if the one i am getting is correct. The output is steady at 3.4 volts & when the needle lifts it goes from 2.9 volts to 3.9 volts,when it is at idle.The amplitude increases when the engine is accelerated. There is no fault code for the sensor, but when i first checked it,it didn't seem to be giving any identifier signal & i thought that when i have looked at other lifts sensors before,they were inductive & gave out a signal switching from 0 volts. I am also not sure which block of data to look at to see if the ecu is showing the correct value. Regards Andrew
