what cable is this

[bronson]

Hi all
Can someone tell me what cable is pink with green dots at the ecu as ive detected some oil coming through this one. Hopefully i can trace it back to the origin.
Cheers bronson

For td5 engined vehicles the source is engine oil from under the rocker cover. It is known that the harness connecting to the injectors can be contaminated with oil which wicks to the ECU. Easiest fix is to get a replacement harness, others have tried washing the oil out.

Ah yes thats correct but ive done the loom mod and with success, although there is ever so slight amount of oil on the seventh pin which has a pink and green wire to it. Hopefully someone can tell me where its coming from? maybe a sensor or something.

cheers

You need to learn how to use RAVE.

A search for the letters KG, i.e., pink/green immediately brought up pin 7 connecting to the engine coolant temp sensor, T121, The return wire is pink/black to pin 18
