Denso DCRI200240 Diesel Injector

On the 3.0L platform, a failing DENSO DCRI200240 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.

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.

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.

Each remanufactured DCRI200240 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.

The DCRI200240 trusted family covers 3 verified vehicle fitments across 1 make: Toyota. Every fitment listed on this page is registry-verified — no scraped or assumed applications.

DCRI200240 supersedes or cross-references 8 further OE numbers, including 295900-0240, 295900-0190, 2959000240, 2959000190, 23670-30170, 2367030170, 23670-39445 and 2367039445. Always match the reference etched on your failed unit's body — cross-references within a family are verified equivalents, but etched numbers remain the source of truth.
