ok so im working on a buddies supra and i cant get the temp gauge to work for the life of me. i fixed the temp gauge in my datsun with a little help from a forum. the main reason why im posting this stupid thread is because i was wondering if there are any tricks for the temp gauge kinda like my datsun(IE gauge cluster gets corroded and stops working til you clean the connection). thanks for reading and YES i used the search button.

Search is good but using the TSRM is better:

yeah i did the basic test already. i was just curious if there was any tricks before i tear apart the harness..... i grounded the connector with the car in the ON position and the gauge didnt move. so it looks like i just have to run along the wire and see whats going on.....
Bummer. Pull the cluster to see if it's making it there. Could be the connection. Wouldn't be the first time I've seen that. Check the cluster separately. Save harness tearing for last...
ok will do. also, the previous owner said the temp gauge would work for a min if he hit a bump on the passenger side...... thats what makes me think its the harness....
In addition to the connection at the cluster, the other likely culprit is the short pigtail and connector from the harness to the sender in the engine bay. Subject to a lot of heat and vibration over many years can cause it to fail.
Could also be M1. Big connector near the ECU. It's the only one the temp runs through on the way to the cluster:

ok, so after looking over the thermostat housing a bunch, i noticed a connector below the temp sensor was broken off, so i fixed that and it still doesnt work.... i cleaned up all the connections i could find...... WTF???
ok so there are 3 different connectors that go into the thermostat housing, what is each one's purpose?
perfect, thank you! sorry for not searching.... thank god i fixed that connector for the radiator fan switch....... thanks again guys!
Way back I had a temp gauge issue, turned out to be a ground from the cluster, I ran a jumper and this solved it.
problem fixed...... long story short, im an idiot and didnt see a broken connector hiding under the power-steering pump..... re-soldered a new connector on, and plugged it in. WORKS. thanks again you guys....
