another crazy.
long ago in Pk a galant GDI rolled into my shop for a transmission issue, Mitsubishi ECS transmission at that time was light years ahead of any toyota as it could double downshift and also modulate the TCC lockup more than 50% in 2 gears.
anyway - long story short, its input shaft speed sensor was bad, it would go bad after driving for about 10 minutes (aka warmup) - another shop had somehow landed on issue of "koi mehenga sensor" by reading the fault code from the TCU. They gave up because mistoobishi ka sensor sirf scrap/kabaar se milta hai. - owner wasnt interested in that.
Took me about 15 minutes of teardown of parts to find the sensor, its wiring after removing top air parts - This "mehenga wala sensor" was a simple pull down hall effect sensor from mitsubishi.
guess what?? - suzuki baleno, hyundai santro, kia spectra all used this same sensor as their camshaft position sensor, literally the same part!!!
I ordered a suzuki genuine part from my parts shop, the rider brought it over - installed and done! customer picked up his car the same evening washed, cleaned and with a printout of the job diag and closure.
now - the sample brigade would be scratching their heads and nads because if you look at the sensor while its installed it looks different to the suzuki part unless you remove it and take off the mounting spacer (which you have to transfer to the new part anyway) - and most wont even touch "automatic gear ka sensor".
point is - they can catalog the part if they wanted to, but that takes a bit time, money and also education. They should be able to know what a HE sensor is and if its pull up or pulldown if they want to build upon the sample system. Like you can order a crank position sensor for an older mercedes v8 and have two different part numbers for the same shape part, one has wiring backwards. Wont start the car because the signal is inverted at the ECU.
