My temperature gauge stopped working, it simply wouldn't read any longer one morning. The red indicator seems to be working, it comes on with key on, goes out after start. The coolant level sensor system is working also.( slow blink with coolant level low) But the gauge reads nothing. It WAS working fine since the time I bought the car. The chassis is a 2000 Boxster S, the engine was replaced with a low mileage unit from a 2002 Boxster S previous to my ownership. The Coolant sensor inside the coolant jacket driver side engine front is a 4-prong unit, and so is the connector. I bought a coolant sensor specific to this car, but its a 2-prong sensor, so thats no good to me.
Has anyone had tihs experience, and if so, any tips on how to test the gauge itself would be much appreciated.
