M57 kaasun asentotunnistin? Sijainti?

[laine]

Otsikko kertonee kaiken. Missäs kiisselis sijaitsee kaasun asentotunnistin? Bensakoneissa olis helppo löytää kun on kaasuläppä - toisin kuin dieselissä.

Ainut asentotunnistin on kaasupolkimessa.

Tarkennas vähän.

Kaasu siis sähköinen, niin siellä pedalin suunnalla jossain?

Pedal Position Sensor DDE 4.0

The DDE control unit is informed of the position of the accelerator pedal by means of electrical signals generated by the pedal position sensor. The pedal position sensor is mounted on the support bracket for the accelerator pedal and is operated by means of a short bowden cable and pulley.

Function

The pedal position sensor is designed as a double potentiometer and features three connection pins per potentiometer.

The potentiometers which receive a 5 V voltage and ground supply from the DDE control unit send measurement voltages back to the DDE control unit corresponding to the angle of rotation (range = 0° ... 70°). This control unit evaluates the measurement voltage and converts the voltage value into pedal position sensor setting as a percentage.

Idle speed and full throttle position

The idle and full throttle positions are detected by way of the voltages of the pedal position sensor.

Troubleshooting

The pedal position sensor is found to be defective if:

• A short/open circuit is detected in the electrical lines
• The supply voltage is found to be faulty or
• The plausibility between both potentiometers is breached

In these cases, one of the two fault codes is stored:

• 0120, "Pedal position sensor 1"
• 0220, "Pedal position sensor 2 PGS"

Consequences:

• Injection volume is limited
• Boost pressure control is deactivated
• A/C compressor is inhibited
