Hi new user need help replaced the throttle body 3x now after “reduced engine power” always the same failure code, replaced the throttle body pedal position sensor assy. Lasts about 3 months each time, something has to be causing it. I just don’t know now??

That's what happens when you shoot parts at a problem without diagnosing. Post the failure code please.
Do you have any engine modifications, after market addons, etc?

 

error is always p2135 have it read every time same error, started by replacing throttle body failed, then replaced pedal sensor, failed, replaced throttle body again(put it on another vehicle I had that was fine (used fir parts runs) it immediately failed in there, then replaced wire harness, failed again! Position sensor is on throttle body!
so I have a new throttle boy, new wire harness, new pedal sensor,no mods that I know of, no add ons that I know of just failed again I appreciate the help but I can do without sarcasm because this isn’t my first rodeo, if I have mud diagnosed it let me know where and how!

thanks again
kevin

thanks Kevin

 

Zero sarcasm. I am dead serious

Would be nice if you provided complete information in your first post.... I'll save everyone else the trouble of looking it up for you here, but the fault he is getting is "throttle/pedal position sensor/switch A/B voltage correlation"


Obviously whatever you did didn't work, otherwise you wouldn't be here
Except, what you did was fire the parts cannon, not diagnose so of course you still don't know what the problem is.
Diagnosing means reading TSBs and schematics, measuring voltages, using diagnostic tools etc. to find what the actual problem is.
If this isn't your first rodeo , then you didn't learn anything in all the previous ones.


Did you perform a diagnostic relearn each time you replaced parts?
Did you verify the sensor position values with a diagnostic tool?

Thanks but no thanks I thought I might actually help, you have a good day
