If this was shagged it would cause shite mpg and would it cause the fans to come on an stay on for awhile after ignition is turned off? Done a quick search on fans but nothing quick came up, oh an what one us the cts??

Both are possible symptoms of dead sensors, but not the same sensor.The mixture enrichment and fans are controlled by different sensors. I'd be looking at either an airlock in the thermostat housing and the engine bay earth points first. ________________________________________ Rich |

The gauge sender is blue, the ECU sensor is green and the one for the fans is brown.On a Rallye the brown one is missing and there's a thermoswitch in the radiator instead for the fans. ________________________________________ Rich |
