Checking needle lift sender -G80- |
The needle lift sender signal is required to determine the commencement of injection. If it fails, the commencement of injection switches to open-loop control (depending on engine speed and load). During normal operation, the commencement of injection is controlled by a closed-loop function (depending on engine speed, load and temperature). |
