LandCruiser Temperature Sensor Issue

Hey, that sounds familiar! I had a similar problem with my old Renault Megane, though not all the same symptoms. The AC refusing to turn on was the big giveaway for me, plus weird readings on the dash. It turned out to be a dodgy connection to the temperature sensor, like a loose wire. Did you check the sensor itself for any visible damage or corrosion? It's usually located behind the front bumper, like the weather vane on a house – easily exposed to the elements.

Thanks for the tip! I did a quick visual inspection, but didn't see anything obvious like a completely broken wire. I'll try to get a closer look at the plug and wiring harness tomorrow. When you say "dodgy connection", do you mean the wire was visibly broken, or was it more subtle, like corrosion inside the connector itself? I'm wondering if I need to get a multimeter out and start testing for continuity.

In my case, it wasn't immediately obvious. The wire looked fine, but there was corrosion inside the connector itself, messing with the signal. Think of it like a rusty pipe – water still flows, but not as well. I cleaned it up as best as I could, but it was a temporary fix. Honestly, after messing with it for an afternoon, I just took it to a workshop. They replaced the connector and it solved the issue. It might be worth checking the voltage, but from my experience, I would advise you to get it checked by a professional.

Thanks a lot for sharing your experience! Sounds like digging deeper into the connector is the next step. I appreciate the advice; I'll probably end up taking it to the shop like you did, especially since I'm seeing similar symptoms. I got a quote for 95€, and I think it's better to have it fixed by someone who knows what they are doing.

I have a Land Cruiser GX here, the temperature gauge stopped working. I tested the fuses and none of them have a problem.

Check the wiring and connections to the temperature sensor for any signs of damage or corrosion. If everything looks fine, you might want to test the sensor itself with a multimeter to ensure it's functioning properly. Let me know how it goes or if you have any further questions!
