I own a , and mine is doing the exact same thing as yours! Hi Magnus, thanks for the description. Car - Pajero 3.
Besides monitoring and applying throttle pressure to the throttle body, it also helps to stabilize the throttle control. It's designed to take input from the driver, but steady the application of fuel pressure as it relays the information from the ECU to the throttle body of the vehicle.
If the sensor is not able to transmit this information to the ECU correctly due to a loose wire, being worn out or have broken entirely, you'll notice a huge difference in fuel economy.
This will signal the Check Engine Light to illuminate on the dashboard. Anytime this light is on, you should take it seriously as there are multiple components that will trigger this warning light.
Contact a local ASE certified mechanic if the Check Engine Light comes on so they can properly diagnose the problem and correct it quickly.
In order to work properly, all of the sensors inside your car must function at percent efficiency. When one fails, it can impact the operation of the entire vehicle. Anytime you notice any of the above symptoms or warning signs, you should contact a local ASE certified mechanic through YourMechanic.

Thanks for that. Voltage amplitudes are produced depending on the position of the rotor relative to the receiver coils in the stator. These are processed in an electronic evaluation unit and then transmitted to the control unit in the form of direct-current voltage.
This evaluates the signal and forwards on the relevant pulse, e. The characteristics of the voltage signal depend on how the accelerator pedal has been pressed.
Using the example of a MB A-Class 1. Ignition on, press pedal, then release pedal. The signal rises and falls depending on the speed at which the pedal is pressed and released. The measurements should be performed by two people. The work involved in capturing the signals on the sensor, carrying out various test cycles, and performing diagnostics work on the oscilloscope is difficult for a single person to handle, and it will take them much longer to complete this work.
