Airrun2002 Posted January 24, 2011 Share Posted January 24, 2011 My temp gauge on my 95 hasnt worked for a whlie anyone got any ideas where to start in troubleshooting this. every once in a while it bumps and will jump up otherwise it just stays at the bottom.

crazyhayseed Posted January 24, 2011 Share Posted January 24, 2011 (edited) Prolly the temp sensor. Easy fix. The trouble-shooting procedure is on page EL-41 in the FSM. I replaced this part in my truck a couple years ago. Seems like it cost around $14. For some reason, I can't find it on any of the parts sites now though. o_O Edited January 24, 2011 by crazyhayseed Link to comment Share on other sites More sharing options...
crazyhayseed Posted January 24, 2011 Share Posted January 24, 2011 NM. Parts train has it listed as Engine Temperature Sensor... They list the other as the Temperature Sending Gauge Switch. I may be backward. The FSM is kinda fuzzy. Test then both and see what happens. http://www.partstrain.com/store/details/Nissan/Pathfinder/Standard/Engine_Temperature_Sensor/1995/XE/6_Cyl_3-dot-0L/SITX18T.html http://www.partstrain.com/store/details/Nissan/Pathfinder/Beck_Arnley/Temperature_Sending_Gauge_Switch/1995/XE/6_Cyl_3-dot-0L/201-1328.html Link to comment Share on other sites More sharing options...
ahardb0dy Posted January 24, 2011 Share Posted January 24, 2011 What I was told and what I did on mine was to pull the connector on the front one (which is the sender for the temp gauge) and connect a wire from the terminal in the connector to ground, with the key on, when you ground it the gauge should go all the way to full hot, if it doesn't the gauge is bad, if it does the sender may be bad. The rear sender is the coolant temp sender that goes to the ECU. Does your gauge move at all other than when it is bumped? Does it just read really low or not move from the cold mark at all? Mine used to go up about an 1/8" than I replaced the thermostat and bled the system and now it reads where it is supposed to. Link to comment Share on other sites More sharing options...

MIne just stays all the way down then every once in a while it will jump up a bit like theres a loose wire. im almost certain the gauge is good as it will work every once in a great while so i might just check the connector on the sensor.
