EJDR00701D — Technical Research
Delphi solenoid common-rail injector (reman code R00701D) for the Ford/Jaguar 2.2-litre Duratorq 16V diesel (engine QJBA, also QJBB/QJBD) fitted to the Ford Mondeo III 2.2 TDCi and Jaguar X-Type 2.2 D (X400). Ford OE 6S7Q-9K546-AA (cross 1361895). Each injector carries a Delphi trim code that must be programmed to the ECU with Ford IDS on fitment. Key symptoms: Rough idle / vibration; Hard starting; Loss of power / limp mode; Black smoke. Common failure modes: Internal wear / high back-leakage; Water-in-fuel corrosion; Nozzle coking.

A leaking injector unbalances cylinder fuelling on the 2.2 TDCi.
Excess back-leakage drops cranking rail pressure.
Out-of-range delivery or rail-pressure deviation cuts power.
Poor atomisation over-fuels the cylinder.
Cylinder-specific injector or fuel-metering codes.
- InstallationProgram the Delphi trim code to the correct cylinder with Ford IDS before road test.
- InstallationRenew the combustion seal and clamp hardware; torque to spec.
- MisdiagnosisRead live back-leakage data to find the weak cylinder before removal.
- WarningThis is the 2.2 Duratorq (QJBA) injector - it is not the 2.0 TDCi (DW10) injector; confirm 6S7Q-9K546-AA stamped on the old unit.
- TestingBench-test on a Delphi-capable CR tester across delivery and back-leakage points before refit.
What is Delphi injector EJDR00701D?+
A Delphi solenoid common-rail diesel injector (reman R00701D) for the Ford/Jaguar 2.2 TDCi Duratorq (QJBA). Ford OE 6S7Q-9K546-AA.
Which vehicles use EJDR00701D?+
Ford Mondeo III 2.2 TDCi and Jaguar X-Type 2.2 D, roughly 2004-2009.
Is it solenoid or piezo?+
It is a Delphi solenoid common-rail injector.
Does EJDR00701D need coding?+
Yes - program the Delphi trim code to the correct cylinder with Ford IDS when fitting.
What is the OE part number?+
Ford 6S7Q-9K546-AA (cross 1361895) references Delphi EJDR00701D / R00701D.
Does it fit the 2.0 TDCi Mondeo?+
No - the 2.0 TDCi uses a different DW10 injector. EJDR00701D is the 2.2 Duratorq (QJBA) injector; confirm the OE number stamped on your injector.
What are the symptoms of failure?+
Rough idle, vibration, hard starting, black smoke, power loss/limp mode and an EML.
Why does my 2.2 TDCi run rough?+
A worn or leaking injector unbalances fuelling; read live back-leakage data and bench-test the weak cylinder.
What causes these injectors to fail?+
Poor fuel filtration, contamination and back-leakage wear - fix the cause first.
Does a remanufactured EJDR00701D perform like new?+
A properly remanufactured injector is bench-tested and recalibrated to the Delphi plan, then trim-coded on fitment.
