I know are fine coz wen i test throttle motor moves up and down and i see my scan tool data changes fine.wen i check accelerator pendle pid is working only in one side.
Seems like the pedal assembly is faulty, that's why they have redundant potentiometers on them, so if one craps out, you're not totally dead on the road.
I'd start with a simple visual of the connector and related harness in the under dash area, maybe even a wiggle test in the area while watching scan data. If you can provide the year, I'll see if I can find a diagram for the American counterpart to this car.
Should be a fairly straight forward diagnosis.
there's going to be 2 wires with their own 5v ref source each, at least one ground, MAYBE 2. And 2 signal wires. One will sweep from 5 to 0v, the other from 0 to 5v. as you move the pedal (probably more likely see 4.75v to 0.5v, but you get the idea).
You're a smart guy, with a backprobe, a multimeter, a flashlight and some patience, I bet you can trouble shoot this without a diagram.

Have not tried but i will be working on that car tommoror oooh.i will post a fix here men!wiring diagram?kindly needed if possible.have discovered mazda e app sensor dnt work exactly like toyota.I mean 2 wires for 5 volts for app 1 and app 2.it is one wire for 5 volts and its signal wire and the other wire has 10 volt for app 2 when unpluged.plugged in 1 volt at idle wen pressing the gas 1 to 7 kindly check it u will see on white wire ooooooh
Oop!!another problem oooo.the car dnt start no injection/ignation pulse and am getting 3.45 on control wire on injectors and 5 volts on ignation coil controll wire wen unplugged,plugged 0 volt.DANNER tells if i have voltage on control wire possibly i have bad computer ground.check the computer ground and it's ok.
And this happened without anything else being touched? Your post is a little vague but I'd expect to see battery voltage at the injectors, even with a dead ecu. You don't say if that's cranking or constant? You have a scope or just multimeter?
