Acura Repair Questions? Ask a Mechanic for Answers ASAP
My name is ***** ***** I would be happy to help. I can tell quite a bit about which part of the system to check by you checking something for me. Start the engine and open the hood. Turn the a/c switch to ON and note if both radiator cooling fans operate when the a/c switch is turned ON. Let me know what you find.
I am not showing a 3 wire pressure sensor in my service information. The 2006 Acura MDX has a two wire sensor according to my service information
Never mind that last statement. The wiring diagram is wrong and different from the picture. In the picture it's a 4 wire sensor, but the wiring schematic is a 2 wire. Give me a minute
Okay, back probe the pressure switch connector at the Blue/Red wire and the Green/Red wire. With the engine running there should be battery voltage on these wires. Let me know what you find. Remember, the connector needs to be plugged up so you'll have to back probe each terminal.
I will wait on your response
