The P2127 code means that the throttle or pedal position sensor switch E has a low input. The pedal position sensor is a sensor found on the gas pedal. The sensor tells the ECU when the gas pedal is depressed and how far it is depressed.
The P2138 trouble code indicates that the Engine Control Module has detected a malfunction within the D and/or E circuits of the throttle position sensor.
no TATA in USA , no year told no engine size diesel told did not scan the PCm or DTC error the CEL lamp on, begging you to do. find a forum in India and win.\ \do put in new fuel filters it is a #1 top service that cannot be ignored.
the limphome mode has many causes GUE$$ing will be super expensive. seems it is already.
google why is my check engine lamp on read. 100rds of ways and millions of posts world wide learn to check all fuses, scan the pcm and the fuel filter can not be ignored on Diesels.
I'm pretty sure your car does not use vacuum advance for the ignition timing. Timing is controlled by the PCM/ECM based on a lot of input from various sensors (engine temperature, air temperature, air flow, throttle position, engine load, RPM, etc.) You don't mention if the check engine light is on or if you've had codes read. What you need is to have the car diagnosed by a qualified technician with the electronic tools to help identify what's wrong.
Anything else is guesswork; could be fuel supply (fuel pump, fuel filter, injectors), could be back pressure in the exhaust system (catalytic converter plugged), could be EGR system, etc. Having the system diagnosed electronically will point to the problem without having to replace a bunch of parts that are not causing the problem.
Look for where the throttle cable connects at the throttle body. If you can move the throttle plate here and get the engine to respond, then the cable is either broken or disconnected at one end or the other. Any other situation doesn't seem likely.
possibly a bad Throttle motor or Throttle position sensor most newer cars do not have Cable operated throttles and are run by a sesnor in the foot pedal and a motor in the throttle body.
I discovered that its the throttle body sensor. Its not sensing the postion of the foot pedal. The throttle body has a sensor that is linked to your gas pedal via a cable. The spring that the repair man mentioned could be the issue. The sensor then communicates to the computer the position and then computer then applies fuel, the mass air sensor then will communicate to the computer and the computer will then allow more or less air to fuel ratio. So if your stomping on the gas and there is not any response, then your throttle body sensor is most likely going out.
