Common failure symptoms
On the 3.0L D-4D platform, a failing Denso 23670-09350 injector typically presents as: diesel knock / injector rattle at idle; rough running when cold; black smoke under load; misfire on individual cylinders; loss of power.
When two or more of these appear together, suspect the injector before peripheral systems — a comparative leak-off test and live-data cylinder-balance review will isolate the failed unit without tear-down.
When two or more symptoms appear together, suspect the injector before peripherals (EGR, glow plugs, turbo). A live-data leak-off test on each cylinder is the fastest route to the failed unit.
What Causes These Injectors To Fail
The documented failure modes on this platform are: injector leak-back rising with wear (documented kd-series trait); nozzle wear causing over-fuelling and combustion damage risk on neglected engines; injector seal leaks allowing combustion blow-by.
Internal wear cannot be repaired in situ — once delivery drifts outside calibration, remanufacture or replacement is the reliable fix.
How Workshops Diagnose 23670-09350 Faults
Do not ignore injector rattle on KD engines — prolonged over-fuelling from worn injectors is documented to cause combustion damage. Compare leak-off across all injectors before ordering replacements. Denso compensation codes must be registered using the manufacturer diagnostic procedure after fitting.
Never condemn a common-rail injector on a fault code alone — codes identify the circuit or cylinder, while leak-off volumes and correction values identify the component.
How Every Unit Is Tested Before Despatch
Each remanufactured 23670-09350 is fully stripped, ultrasonically cleaned and inspected; worn components are replaced with OE-grade parts. The rebuilt unit is then calibrated on a common-rail test bench against the manufacturer's specification sheet — delivery, back-leak and response are all verified before the injector is sealed and despatched with its calibration data on file.
Every unit carries a 12-month parts warranty and free UK delivery.
