Iwan-g-g Posted August 28, 2014 Share Posted August 28, 2014 Hey guys. Posted here few weeks ago that my glanzas engine management had come on. And missing and trouble starting. It was the coolant temp sensor. So I replaced it and it was perfect but last night it did the same thing and comes up as coolant temp sensor again. Don't see how it could be that again. Any other ideas? Cheers Quote Link to post Share on other sites
fiddlersport Posted August 28, 2014 Share Posted August 28, 2014 might have a break in the wire possibly ? Quote Link to post Share on other sites
Iwan-g-g Posted August 29, 2014 Author Share Posted August 29, 2014 The cables are intact. I forgot to mention the engine management will come on for 5 seconds and go off again. Then 5 minutes later come on and off after 5 seconds Quote Link to post Share on other sites
morgey Posted August 29, 2014 Share Posted August 29, 2014 Air lock? Quote Link to post Share on other sites
Stu Posted August 29, 2014 Share Posted August 29, 2014 Air lock is definitely a possibility - if you've replaced the sensor with a new genuine unit then it could be either wiring or ecu. Quote Link to post Share on other sites
Iwan-g-g Posted August 29, 2014 Author Share Posted August 29, 2014 Ive pulled out all the senors and gave them a good clean and popped them back and it seems to be ok for now. But will need to give the rad a good wash out and the engine too as it's gone all rusty. Last night when I out my foot down it bogged out then picked up then once I let go of throttle it juddered until I put my foot down again. Quote Link to post Share on other sites
fiddlersport Posted August 29, 2014 Share Posted August 29, 2014 isnt the coolant temp sensor earthed against the body of the thermostat housing, check your earths on the engine Quote Link to post Share on other sites
Iwan-g-g Posted August 30, 2014 Author Share Posted August 30, 2014 I pulled the sensors out yesterday and gave them a good clean and all seems well ATM fingers crossed. But will update if something happens again. Cheers. Quote Link to post Share on other sites
Stu Posted August 30, 2014 Share Posted August 30, 2014 isnt the coolant temp sensor earthed against the body of the thermostat housing, check your earths on the engine No the engine water temp sensor is earthed to the sensor earth pin from the ecu - the radiator fan temp switch and the dash guage sensor use earth from the housing.
