1991 240sx

[mjsdfd6]

My 1991 nissan 240 recently developed a prob;em that maybe someone has come acrossed. While driving down the road the speedodometer & Tach quit working. The temp gauge and fuel gauge went all the way up! I checked all fuses and they are not blown i also swapped a few of them out. I reset the computer by disconnecting the batt for a few hours as i was told. If i disconnect the temp sensor the temp gauge goes down to nothing. Everything else in the car works fine including all idiot lights in instrument cluster. I just don,t know where else to look please help.

check for corroded connections... frayed wires... check ur ECU see if its throwing codes...

usual diagnostic stuff
