Please help I can't afford a mechanic? Show Less
Chris
A:BEST ANSWERHi Christopher, I'm glad to assist you. The coolant temperature sensors are used by the fuel management system to detect the engine's operating temperature. Depending on the sensor information, the control unit (ECM) adapts the injection time and firing angle to the operating conditions. It is best to have your car checked by a certified mechanic if there are other defective parts since using the correct tools and troubleshooting procedures would protect your vehicle from wrong or inappropriate diagnosis. Show less
