I have looked at some posts and havent noticed a solution being posted. My old sensor was reading pretty close at lower temps....then 40c when it was 21c now tje new one goes from 10c and then sits at 48c without change. Did anyone come up with a fix/solution?

The sensor is a negative temperature coefficient thermistor which means its resistance drops as the temperature increases. It reads from -40C to +50C. Since you are reading temps too high, almost at the upper limit, the resistance in the circuit between the DME and the sensor is too low. It sounds like you have tried a new sensor with no improvement. So you have a short to ground in the signal wiring between the DME and the sensor.

What voltage do you read at pin 2 of the harness connector at the sensor with the sensor disconnected?
