True, none of the parts are manufactured by the parts stores. But the part I bought was from China and would not sweep voltage in line with the specifications. I read 0.48V with plates closed, 3.0V at WOT. From what I could find, specs calls for approx. 0.5V at idle, 4.8V at WOT. Oreilly was cool with upgrading to a BWD unit. (Which hopefully isn't coming off the same production line.)
Good point on the linkage. I am sure of WOT because I swept the throttle shaft by hand under the hood with laptop on the dash. 100% needs to happen with the throttle blades fully open. Once the TPS sweeps correctly the pedal can be checked with the laptop.
