Someone please help me, I'm dumb but like nice cars lol. I own a 2001 m35 nissan stagea, it's auto. Has electronic throttle body. Accelerator isn't working and it won't rev, it idles fine but tiny bit low, believe it's in limp mode as when I last had the car is was shutting down loosing power and wouldn't drive over approx 12kms, if you press the accelerator the bit inside the throttle body doesn't move. Wire that lead to throttle body and pedal both have voltage. I had in scanned by a mobile mechanic and no codes came up which i thought was strange but the guy said it was a good sign.

My brother who doesn't know much about imports thinks it could be the accelerator pedal sensor and took a photo of it for me and told me to locate someone selling that part, the number on the part is 18919-6N201 but when I search it nothing to do with a stagea comes up. Basically I'm after a part number so I can see if that's the issue and I'm also very very open to any other ideas to what my problem could be. My car was stolen and since having it recovered it's been this way.

    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked... HTH
    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily. 
    • Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
