OK, so I was waiting for one from ebay to come,
The Co Pot is a 5.82K Pot and this reads across PIN 1 and PIN 3
PIN 1 to PIN 2 = 4.4K and PIN 2 to PIN 3 = 1.63K


4.4 + 1.63 = 6.3K so I can only assume there is an offset resistance in the Signal output or wiper leg of the Pot of about 200 to 300 Ohms
PIN 1 = GND
PIN 2 = Signal to ECU
PIN 3 = 5V Supply (V-Ref)


Would anyone else care to share their values?, mine has the cap on but clearly been tampered with.
