Yes but it has three wires going to it Violet, Blue, beige. I have identify that the beige is the +5volts, the blue is signal to the ecm and the violet is the ground. The problem is that this cables connect to a pigtail that goes to the pressure sensor which the colors change to red, black and blue. Need to match them
