P1542 EPC Throttle Driver Angle sensor : Implausible signal

Fault code P1542 Throttle Driver Angle sensor : Implausible signal is related to the problem with throttle body. Throttle body is use in engine at intake manifold to control the amount of air entering into the engine. When driver press accelerator pedal position sensor, it send a signal to the engine control module (ECU) . Engine control module (ECU) use this signal to open or close throttle body to occupy the requirement of air fuel ration. Throttle body is controlled by wire and it has it own internal motor which is use in opening and closing operation. when ECU detect any faulty signal then fault code P1542 Throttle Driver Angle sensor : Implausible signal is set in the engine control module.

When found in VW petrol engine vehicle like Polo, Vento, Golf etc. In these type of petrol vehicle when fault code P1542 Throttle Driver Angle sensor : Implausible signal is set in the engine control module. It is possible that it can create trouble in starting, as it is control by engine control module (ECU).

So if fault code P1542 is present in ECU and you are getting problem while starting. then disconnect the throttle body socket and try to start the engine. If faulty throttle body is creating no start than it will solve your problem.

Causes of P1542 Throttle Driver Angle sensor : Implausible signal :

  • Faulty throttle body control module.
  • internal failure of engine control module.
  • Damage wiring harness of throttle body.
  • Also faulty accelerator pedal position sensor.

Symptoms :

  • Throttle body may not operate when accelerate paddle is press.
  • Engine light will illuminate on cluster meter.
  • fault code will store in engine control module.
  • Also hesitation in engine.

Solution P1542 Throttle Driver Angle sensor :

  • Replace faulty throttle body.
  • repair or replace engine control module.
  • repair damage wing harness of throttle body.
  • replace faulty accelerator pedal position sensor.

How to trouble soot fault code P1542 :

  • mechanic should start diagnosing this fault code from scanning the fault code and its status. if it is present in intermittent or active.
  • check the signal of accelerator peddle or opening and closing of the throttle body. observe the faulty signal and start diagnosing that component.
  • Most of the time when this fault code is occurs and create no starting problem. It is quit sure that the reason behind that is a faulty throttle body. To solve this problem just disconnect the throttle body and again try to start, it will definitely solve the problem.
  • if it does not solve the problem that it is quit possible that engine control module is faulty.
