Broken wires. I cut the wires at the connector. There are around 5-10 mm left on the plug. I stripped the insulation back to bare the copper. The loom is in a worst state. The outer protective cover was opened with a sharp blade, being careful to cut in and up, so not nic the insulation. But as solder would not take, I had to open more if the insulation back to near the start of the branch. Managed to semi tin the wires, after grabbing them with fine san paper, in an attempt to clean the copper. Then as solder didn't work, I crimped the copper lines together. Plugged back in to the sensor and the coil remained unlit. YES!! The engine light did remain lit though.
So I live at number 7 and my local garage owner lives at number 3. I popped along to his, and at 7pm his car was not back so I drove to see him. He popped the computer on the van and cleared the faults, and they remained clear!! Yes!
The initial fault was the middle seatbelt pre tensioner, commonly know as Airbag light, on this forum. I had measured the resistance of the pre tensioner at 2.2 ohms and the 2.4 ohm resistor has done the trick!
My van is fixed, albeit temporarily as I want a proper fix to the fuel temp sensor wires, (P0138 fault code) so will order new parts and drop it off at the garage next Friday.
Great thread, another issue resolved by us!
