Paul Grainger Posted April 22, 2017 Share Posted April 22, 2017 Set your meter to 0-20 volts DC you will need the sensor connected and the ignition switched on. There are three wires at the sensor. One is an earth, one is a 5v feed and the last one is the reference back to the ECU. Probe the reference wire using a paperclip so you don't damage the wire. You should have roughly 0.5v at idle. Slowly depress the throttle and the voltage should slowly rise until you get to full throttle which should be roughly 4.5v You are looking for the voltage dropping out enroute. After this disconnect the battery for a few minutes to clear the KAM codes just in case you have caused any voltage drops as the ECU will create new idle values. Good luck.
