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, T

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. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

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. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

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
