Should you measure the voltage? The ignition switch has a resistor in it. Only send a small signal to the ecu. Maybe this has one too?? I’ve not done it.Of the three wires that connect to the sensor, the black yellow is an earth, so maybe its the 2 others that need connecting together ?
Absolutely.Hmmm indeed. I found this after an in depth google search
The sensor has three wires going to it. Can you cut and cap brown/black wire. Then can you connect the blue and the yellow/green wire with a (1/4watt 68k) ohm resistor between them to get the right voltage going to the ecu 4.5 volts i think to run fuel pump ?????www.zx-10r.net
