ger040 2 Posted March 6, 2011 Took some advice of here about my corrado not running correctly and one advice was to change the blue temp sensor (supercharged) - i ordered the parts (inc housing) and what a big difference it made - car now idles and revs freely , fuel consumption is also reduced - just why is this sensor so important ? What exactly does it do - iam just interested to know. The only thing now is the temp gauge on the dash does not work - is this the black sensor beside the blue sensor ? And should i replace it also many thanks for the advice guys and no doubt i will be calling on you again as i get the car roadworthy and saving money too Quote Share this post Link to post Share on other sites

It also provides the trigger for when the ECU starts to use the lambda probe for adjusting the fuelling. It allows the ECU to set the position of the idle stabiliser valve during start up enabling a smoother idle when cold, acceleration enrichment and finally timing advance. If it is broken the ECU assumes a value of > 60 degrees C coolant temperature but you will not get any timing advance, acceleration enrichment or a refined idle during warm-up. The black sensor provides the coolant temp gauge with a signal for temperature so I would try a new one of those before anything else. Quote Share this post Link to post Share on other sites
