bullsnuts Posted March 1, 2008 Report Share Posted March 1, 2008 We have a 1998 Caddy Eldorado , code c1738 ( exhaust soleniod short to ground ) keeps coming up as current. I have located it and have noticed that the fresh air supply hose is off and was wondering if some dirt could have entered the system and caused the system to malfunction? I also unplugged the 2 wires coming out of the soleniod and the code still comes up ... Any help will be greatly appreciated. Thank You in advance..

Ranger Posted March 1, 2008 Report Share Posted March 1, 2008 I doubt that would cause a short. Check for a chaffed wire maybe. If not, you'll probably have to change the solenoid. Link to comment Share on other sites More sharing options...
