1.9 watercooled temp sender wiring fault?
Posted: 16 Mar 2012, 13:49
Hi
My temp gauge stopped working so i replaced the sensor/sender but it didnt fix. Ive checked on the haynes maual wiring diagram and it shows that the sensor has a brown wire and a red/yellow wire that leads up to the gauge. My sensor however, has the brown but also a lilac/black wire instead of the red/yellow. This leads into the junction box at the back of the engine bay and goes to a relay and not a connector plug. Does anyone know what the relay does? Also if i short the red/yellow to the lilac/black, the temp gauge reads half but even when cold. Cheers
