So to further complicate things or hopefully explain better: This is a VDO sensor. It clearly does this math inside the gauge itself... because it displays a temperature in C to me instead of a voltage. The signal wire to the gauge is in Volts, not Ohms. I have just teed into this and sent it to the ECU. ChatGPT spat this out: Temperature (°C) Thermistor Resistance (Ω) Voltage Output (V) -40 36563.56 4.973962698 -35 26284.63 4.963854097 -30 19149 4.950518086 -25 14127.68 4.933166097 -20 10504.68 4.910527969 -15 7721.35 4.879055954 -10 5720.88 4.838133512 -5 4284.03 4.786165799 0 3240.18 4.721119717 5 2473.6 4.640900563 10 1905.87 4.543692515 15 1486.65 4.429695182 20 1168.64 4.296344225 25 926.71 4.144091368 30 739.98 3.972492431 35 594.9 3.782907287 40 481.53 3.577860996 45 392.57 3.361217186 50 322.17 3.136573398 55 266.19 2.908608143 60 221.17 2.68039363 65 184.72 2.455599277 70 155.29 2.239608872 75 131.38 2.035132288 80 112.08 1.846579676 85 96.4 1.674774149 90 82.96 1.511882199 95 71.44 1.359001674 100 61.92 1.222169588 105 54.01 1.100403407 110 47.24 0.989775394 115 41.42 0.889528391 120 36.51 0.800974069 125 32.38 0.723478416 130 28.81 0.654148313 135 25.7 0.591893137 140 23 0.536380597 145 20.68 0.487551867 150 18.59 0.442640126 155 16.74 0.40213318 160 15.11 0.365841848 165 13.66 0.333073247 170 12.38 0.303758956 175 11.25 0.277572169 180 10.24 0.253917873 -
Can you measure resistance between the pin you're wiring to, and the sensor ground? -
Not 10 out of 10 crap. But just so......disappointingly....bleh. Just didn't do anything well. Everything was bland. Didn't even have a long enough life to justify the ongoing daily disappointment. Although I was so happy to see them go that I'm glad they didn't last longer. -
Not enough to make any difference at all.

Don't they cool down technically when you're sitting at a set of lights?
