Gauge-Temperature-Repair
From MS4X Wiki
If your Gauge Cluster is showing 50 Celsius as Temperature, and its not the faulty sensor/wiring(check with different cluster), you can try the following fixxes:
1. Check if R1 and R2 have correct Ohm Values with your multimeter. Replace if they are not. Small tolerances(-/+20%) are okey.
2. Check if Temp VCC is connected to R1 and R2 correctly. If broken, do a fly wire to connect them correctly
3. Check if Temp-GND Pin is connected to Ground. If broken, do a fly wire to connect them correctly - see picture
