My mistake tps is pin 17 I have corrected all the posts with the correct pin outs for future search referencing
These things happen when you are an old senile confused old antique like me lol
Is your ecu powered up and are you doing your tests with the ecu plugged in and back probing the pins, is your meter set to 20volts DC
pins 1and 19 are ecu earth and are connected to the inlet plenum, pin 20 is battery voltage +ve. You should get battery voltage at 1 and 20 also at 19 and 20 whilst the ignition is on or the engine is running
Take a measurement between pin 11 and pin 30 ignition on and ecu plugged in
you should get 4.7-5v
Pins 11 and 15 ignition on engine not running 2 bar map should give you 2.3volts
3 bar 1.5volts should read 1.7 volts
