The 0445010107 Bosch CR (Common Rail) Injector Pump is a high-pressure fuel pump designed for certain Ford and Mazda diesel engines equipped with common rail fuel injection systems. Here are the key details you should know:
Compatibility:
This pump is commonly used in Ford and Mazda diesel vehicles, including:
Ford Focus TDCi (1.6L, 1.8L, or 2.0L diesel engines, depending on model year)
Ford Mondeo TDCi
Mazda 6 MZR-CD (diesel variants)
Mazda 3 MZR-CD (diesel variants)
(Always verify exact compatibility based on your engine code and model year.)
Function:
Generates extremely high fuel pressure (up to 1,600+ bar in some systems) for common rail injection.
Delivers precise fuel amounts to the injectors based on ECU signals.
Works with the Bosch CP1, CP3, or similar high-pressure pump series.
Symptoms of a Failing Pump:
Hard starting or no-start condition
Loss of power or limp mode
Engine stuttering/misfires
Increased fuel consumption
Fuel leaks (if seals are worn)
Fault codes like P0087 (low rail pressure) or P019x (fuel pressure sensor issues)
Replacement & Repair Tips:
Diagnose Properly – Use an OBD-II scanner to check for rail pressure issues before replacing.
Check Fuel Quality – Contaminated diesel can damage the pump.
Consider Remanufactured Units – Bosch offers rebuilt pumps that are more affordable than new ones.
Professional Installation Recommended – High-pressure systems require precise calibration.
