What It Is
A genuine Bosch fuel rail pressure sensor (Bosch part 0281002858) for common rail CJAA, CBEA, and CKRA TDI engines.
What This Sensor Does
It monitors pressure in the fuel rail and reports it to the ECU, which uses that data to regulate the high-pressure fuel pump and injector timing. A failing sensor can trigger a rail pressure fault code and cause rough running or reduced power.
Fitment
Common rail TDI engines with the CJAA, CBEA, or CKRA engine code.
