Hi, sorry but the pin layout is not what I'm after. I need the pin data so I can check out readings of all the connected sensors / equipment. Should show the readings expected for each connected sensor ect

All of them. Having problems not showing on ecu

Hello again,
Accelerator pedal position sensor: 0 to 5 volts as the position increases
air mass meter: 1 to 2 volts at idle, increasing with throttle opening
coolant temperature sensor: 2.5 kohm with engine cold to decrease to 300 ohms as engine is warm
fuel metering unit (solenoid) on pump: should receive battery supply (pulses), internal resistance around 3 ohms
rail pressure sensor: around 1 volt at idle, and 0.5 kvolts ignition on, engine off, maximum 4 volts engine running at full throttle
EGR motor: 5 to 15 ohms internal resistance, gets battery voltage with ignition on.
EGR position sensor: 1.6 volts with engine idling, increasing to 4 volts with engine getting higher rpm
glow plugs: battery voltage within 12 seconds of ignition on, engine cold, internal resistance about 0.5 ohms
crankshaft sensor: around 300 ohms internal resistance, voltage signal amplitude around 4 volts, alternating spike wave
camshaft sensor: amplitude 12 volts, square wave
And here is the wiring diagram:

Looks great, just what I'm after but please check rail pressure sensor figures think typo, you have put 0.5Kvolts??
Expert:  Billy replied 1 year ago.
Hello,
My apologies for the typo, it is actually 0.5 volts with ignition on, 1 volt when idling, and increasing with snap throttle till around 4 volts.
Regards,
Billy
