wilkorangerover Posted June 10, 2009 Share Posted June 10, 2009 (edited) A few months ago i installed a prosport afr gauge for my single turbo supra. It has worked fined everytime ive used the soop until last night i noticed it just saying 19.9 all the time... So ive looked at the bosch sensor end to check wires etc...there ok as soon as i pulled the gauge out it twitched to the right readings for a few seconds then went back to 19.9 all the wires are ok to the gauge etc... So i am thinking the gauge has gone even tho its only 2-3months old Iam not happy:( Edited June 10, 2009 by wilkorangerover (see edit history) Quote Link to comment Share on other sites More sharing options...
Robert Posted June 10, 2009 Share Posted June 10, 2009 could just be the sensor needs replacing, where do you have the sensor mounted? Quote Link to comment Share on other sites More sharing options...

Robert Posted June 10, 2009 Share Posted June 10, 2009 yeah sounds like the sensor is dead, i know it being so soon is a pain they should last a few years at least. Quote Link to comment Share on other sites More sharing options...

wilkorangerover Posted June 10, 2009 Author Share Posted June 10, 2009 i` ll go and check now... hope that s the problem, the seller is telling me the gauge needs calibrating ?? Quote Link to comment Share on other sites More sharing options...
Robert Posted June 10, 2009 Share Posted June 10, 2009 well that might be true but from the start not after 3 months it goes dead and THEN needs calibrating. I wouldn't expect anything else from the person who sold it to you and after 3 months the sensor is dead. Quote Link to comment Share on other sites More sharing options...

Robert Posted June 10, 2009 Share Posted June 10, 2009 Again mate honestly i can't see it being that, if so it would have required sorting out as soon as you fitted it not a few months down the line. Quote Link to comment Share on other sites More sharing options...
