mudduck Posted July 11, 2009 Share Posted July 11, 2009 Working on a 92 Legacy. The gas gauge goes down to empty when the car is started, and after a minute or two goes back up to where ever it was before the car was started. I'm thinking its just a corroded wire on the sending unit. Am I going in the right direction? Link to comment Share on other sites More sharing options...
Cougar Posted July 11, 2009 Share Posted July 11, 2009 There is a voltage regulator in the circuit I believe and the trouble may be with that. Link to comment Share on other sites More sharing options...
Legacy777 Posted July 16, 2009 Share Posted July 16, 2009 Do you have any issues with the guage while driving, or only after startup? Does it happen at cold starts only? Link to comment Share on other sites More sharing options...
nipper Posted July 16, 2009 Share Posted July 16, 2009 Im betting its the gauge voltage regulator. nipper Link to comment Share on other sites More sharing options...
