Q: What does code P1352 mean?

Needle Lift Sensor. P1352 on Mercedes-Benz diesel engines indicates that the engine control module has detected an implausible or missing signal from the needle lift sensor, which is integrated into the fuel injector on cylinder one. The sensor reports the exact moment the injector needle opens, allowing the computer to fine-tune injection timing; when the signal is absent or erratic, the module sets this code and typically defaults to a calculated timing value.
