Andy9376 Posted June 4, 2019 Report Share Posted June 4, 2019 Evening all, My car threw a warning fir the temperature sensor today. It completely dropped to zero, then started working a few mins later but it moves around rather than sitting still. Is this purely a sensor issue? And how much would it be to fix? I’ve had an overheating issue last year so I’m a bit paranoid about driving it with a dodgy or broken sensor. Link to comment Share on other sites More sharing options...
Nobbie Posted June 4, 2019 Report Share Posted June 4, 2019 Sounds like it, unless there is a wiring fault. Sensor is about £20-30 from Porsche and about half an hour to fit and maybe then need to leave the bleed valve open to let any air escape. I'd guess £100-150 Link to comment Share on other sites More sharing options...
Andy9376 Posted June 4, 2019 Author Report Share Posted June 4, 2019 Ok thanks Nobbie. Do you think it will be safe to drive until I can get it fixed? Link to comment Share on other sites More sharing options...
Nobbie Posted June 4, 2019 Report Share Posted June 4, 2019 I'd check the radiator fans still come on in case they are fed from this sensor as well, although I think there is a second sensor that controls them. If the fans don't come on, the car could overheat in traffic. Link to comment Share on other sites More sharing options...

I’m a total novice in terms of the workings of the car Link to comment Share on other sites More sharing options...

iborguk Posted June 4, 2019 Report Share Posted June 4, 2019 Don't know what model year you've got but online workshop manuals available at https://workshop-manuals.com/porsche/ Radiator section on mine at https://workshop-manuals.com/porsche/boxster_(987)/f6-2.7l/engine_cooling_and_exhaust/cooling_system/radiator/component_information/service_and_repair/procedures/ Link to comment Share on other sites More sharing options...
Andy9376 Posted June 4, 2019 Author Report Share Posted June 4, 2019 Thanks both. It’s a 987 3.2. I’ve just watched a video and it said that a stuck sensor could cause the car to seriously overheat? Can that be so, as I’d imagine (maybe incorrectly) that the sensor merely reports back the temperature, rather than controlling anything, unless as Nobbie suggested, it may control the radiators.

iborguk Posted June 4, 2019 Report Share Posted June 4, 2019 All conjecture via remote internet diagnosis, I'd say get it in with someone who can pull the error codes and tell you what is going on. I did find this .... Link to comment Share on other sites More sharing options...

I did find this .... Thanks for sharing that. I just ran the car on the drive for a while. I felt a very slight flow of air below each rad. I think there is a leak from the crossover pipes. Not sure if related. I believe they’re pretty pricey to fix? Link to comment Share on other sites More sharing options...
iborguk Posted June 4, 2019 Report Share Posted June 4, 2019 No problem and again I'd recommend go get it checked by someone in the real world. Radiator pipes price guide, those are genuine Pork https://www.design911.co.uk/fu/prod138378/Radiator-pipes-replacement-kit-Porsche-997-Gen-2/ I'd check pricing with an OPC but before you worry yourself on it, again I'd get it to someone who can help re the diagnosis and go from there....that way you know what you're dealing with.

I’ll try and get it to my Indie as soon as. Hopefully it’ll be ok for the next couple of days. Link to comment Share on other sites More sharing options...
