exora turbo mpv 2012 milage 100,000km
problem engine light on, cvt light on, and rpm meter goes maximum (8,000rpm) without engine on just ignition on (even engine on rpm still stay at maximum)
car can start but in limp or home mode cannot accelerate moving at only 20km
change accelerator peddle sensor, swap ecu and tcu, clean throttle body, check wirings but still the same problems

obd2 error code
P0642 - powertrain
P2135 - throttle pedal position sensor
P012c - powertrain
C1555 - chasis
U1013 - network
U1012 - network
P005A - powertrain
P1401 - powertrain
P00D0 - powertrain
P0700 - transmission control system
P0128 - coolant thermostat

Hi, this car isn't sold where most here deal with US based cars/vehicles only so very limited.
Just the same if engine always thinks it's spinning at 8,000 RPM that sensor is probably leading to all the other codes would default to limp makes sense. Have to leave the hunt to you where it senses RPM at crank or a cam sensor? Just a strong hunch the source problem,

Although the Crank sensor measures engine rotations, it does not report directly to the tachometer and does nothing at all when the engine isn't rotating so don't waste your money on that sensor right now.

You have both module communication and electronic throttle codes that should be your priority.

The communication codes mean there are at least one module that is not working with others or at all.

The throttle code would explain your lack of acceleration as it would go into a half throttle limp mode due to the code.

In addition to all that you could have a major transmission problem. Those CVT transmissions are a total nightmare.

exora turbo auto 1.6 cvt 2012
after changing throttle pedal sensor, clean throttle body and replace crank sensor remain three errors codes
P012c - pressure upstream throttle sensor short circuit to ground
P0642 - sensor reference voltage A circuit low
P2135 - throttle position plausibility
engine light and cvt light still on error after reset
check cvt oil level ok
check wirings but could not find any problem

any help appreciated very much

We aren't going to be much more help as Tom already stated, we don't have that vehicle here in the US so we don't have any info on it.

Troubleshoot the codes one at a time. If they are related, you will find that out in the process.

exora turbo 2012
after replacing the mass air flow sensor, P012c - pressure upstream throttle sensor short circuit to ground disappear
now only remainder two error codes out of three
P0642 - sensor reference voltage A circuit low and P2135 - throttle position plausibility (this two error codes still remain)
but when remove throttle body electrical plug the rpm meter reading always reading maximum (8k rpm) drop to zero
and check error codes now difference two error codes - suspect throttle body unit will replace waiting for spare and later will report

Glad you got it figured out.

Closing this now as solved.
