attrabeutz Posted December 5, 2004 Share Posted December 5, 2004 I have a 1996 LS 400. The outside temperture guage is reading -22F. Any ideas where I need to start to troubleshoot this? Thanks Quote Link to comment Share on other sites More sharing options...
Jacob Posted December 5, 2004 Share Posted December 5, 2004 I think you should start with the ambient temperature sensor at the front bumper. It might be dirty or something. Good luck. Quote Link to comment Share on other sites More sharing options...
wwest Posted December 5, 2004 Share Posted December 5, 2004 Reading -22 is a pretty sure bet that the OAT sensor connection is completely open or else the sensor (thermistor) itself is. If I remember correctly 4800 ohms is about 32F. Quote Link to comment Share on other sites More sharing options...
90LS400Lexus Posted December 9, 2004 Share Posted December 9, 2004 Are you sure it is not -22 outside? Just kidding! I could not resist! :D I agree with the others - probably the sensors. Good luck! Quote Link to comment Share on other sites More sharing options...
