Right I know it's pin 53 on the ecu so if I run a wire from there to the sensor where would I run the other wore to as I don't really understand the wiring diagram, thank you

Im inclined to believe I have wiring issues with the temp sensor as well albeit on my PD130. Does your temperature gauge move at all?

it has a dual circuit, one set of terminals will tell the ECU the temperature so it will adjust the mixture to suit and the other gives your gauge its reading

mine was running ok although i have no clue where there reading is coming from as i have a coolant temp sensor with no plug in it on the top rad hose from the agu it would just sit at 90 which i was happy with but i was fiddling to sort my lights out and now i have a flashing light on the dash and no reading atall and the mpg has gone to sh!t so i need to know the pin outs so i can trace where the coolant temp sensor wiring is going to, does any one have any info that could help me?, would be greatly appreciated
