Throttle position sensor
96 Mariner 225 magnum efi. While testing the TPS I have 4.75 volts going in on the blue and yellow wire. With key on throttle closed I have 3.76 volts coming out on the blue with red wire. (Should be 0) With key on press the throttle slowly volts drop to
.74 volts. (Should increase)
Does this indicate a bad TPS?
