As part of my project, I want to monitor the engine coolant temp in a vehicle. The coolant sensor uses a 5v input, and the output (varied based on temperature) goes back to the ecu. If I connect a wire to the sensor return, say near the ecu, and have it as an analog input into a pic, is it going to alter the temp reading going to the ecu?
Sorry for the newb question, and thanks for any answers.
