If the above-mentioned problem is identified, one possible cause may be a defective exhaust differential pressure sensor.

In order to exclude other possible causes of malfunction, electrical and mechanical system tests (in accordance with vehicle manufacturer specifications) and also an error code query using a suitable diagnostic unit should be carried out.

First perform a visual inspection of the plug connections/sensor hoses to check for contamination and damage and, if necessary, clean them with suitable cleaning agents. Alternatively, if damage has occurred, replace these parts in accordance with vehicle manufacturer's instructions.

If no other kind of malfunctioning is detected, the exhaust differential pressure sensor is to be replaced.
