F00RJ02697 (F 00R J02 697) — Bosch Injector Solenoid Valve (Professional Product Detail)

The F00RJ02697 solenoid (also written F 00R J02 697) is the electromagnetic actuator that controls fuel injection timing and duration inside many Bosch common-rail injectors. As a fast-acting on/off valve it governs nozzle opening under electronic command - a small part that has a major effect on idle quality, transient response and emissions when it fails or ages.

 

 

This component is the solenoid coil + valve assembly that sits on the injector body and receives pulses from the engine control unit (ECU). When the ECU energizes the solenoid, hydraulic pathways open or close to allow controlled injection events. A degraded solenoid can cause misfires, long cranking, limp mode, or increased smoke - so replacing a faulty F00RJ02697 is a common and cost-effective repair in injector servicing.

 

 

The F00RJ02697 is widely used across many Bosch CR injector families (CRIN1-14/16 style injectors) and is commonly referenced for injectors used on 5.9L Cummins applications (Dodge 2003–2007 LB7) and other heavy-duty petrol/diesel platforms. Vendors and parts houses list dozens of compatible injector part numbers - always confirm fitment with the injector tag or pump/injector serial before ordering.

 

 

• OEM-style replacement for Bosch solenoids - designed for plug-and-play fit. 
• Robust construction to withstand injector environment (fuel, vibration, temperature). 
• Supplied individually or in multi-packs for remanufacturers and workshops.

 

 

🔎 Visual first: inspect the connector, wiring and seat for corrosion or damage.
🧰 Electrical check: measure continuity across the coil with a DMM (compare all injectors on the engine so you spot an outlier). If one solenoid shows open circuit or wildly different resistance vs other cylinders, replace it.
🧪 Functional bench test: re-fit the solenoid to a test injector and verify response/actuation on a calibrated bench - observe spray pattern, opening timing and return flow. Bench validation prevents unnecessary rework after installation.

 

 

• Engine misfire codes or cylinder cut-out.
• Long crank or hard start conditions.
• Increased smoke or reduced power under load.
• Irregular injector response during bench calibration.

When one or more of these symptoms align with an electrical or bench fault, replacing the F00RJ02697 solenoid is frequently the corrective action that restores injector performance.

 

 

The F00RJ02697 looks small - but its role is central to precise injection control. For technicians and remanufacturers, sourcing traceable solenoids, bench-validating after fitment, and following clean installation practices are the best ways to return engines to reliable service without unnecessary injector swaps.
