Temp gauge just stopped working

Hello, it's all a total guess, but the same component that shows the temperature at the temperature gauge is also the same one that provides engine temperature data to the engine's computer so it can know how to properly adjust engine timing, fuel and spark and air mixture ratios. If the temperature is not being recorded, then problems occur. The sensor or related wiring could be a concern. Also the engine temperature itself may not be getting to where it needs to be, from a possible thermostat issue, among other possibilities. Hands on testing is needed. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554. We'll gladly find you a certified RepairPal shop in your area.
