DENSO DCRI107640 Diesel Injector

2.2L D-4D · Remanufactured

Remanufactured DENSO DCRI107640 (095000-7640) common-rail diesel injector for the Toyota 2.2 D-4D (2AD-FTV) — fits RAV4 III 2.2 D-4D 2006–2012, Corolla Verso 2.2 D-4D 2005–2009 and Auris/Avensis 2.2 D-4D applications. Toyota OE references 23670-0R170 / 23670-0R120 / 23670-0R070 / 23670-0R020 / 23670-09140 / 23670-09210 / 23670-09290. Note: 2AD-FTV engine-code lookup resolves to the established 23670-26011 family; verify by the DENSO/Toyota number etched on your old unit. 23670-0R040 is a different injector (DCRI200110) and is NOT covered by this unit. Fully tested and calibrated to OEM specification with 12 months warranty.

Common DCRI107640 injector failure symptoms

Hard starting or extended cranking; rough or uneven idle; loss of power under load; excess smoke from the exhaust; cylinder misfire or contribution fault codes. When two or more appear together, suspect the injector before peripherals — a comparative leak-off test isolates the failed unit without tear-down.

What causes these injectors to fail

Injector back-leak beyond specification; nozzle wear degrading the spray pattern; combustion gas leaks past the injector seat washer. Internal wear cannot be repaired in situ — once delivery drifts outside calibration, remanufacture or replacement is the reliable fix.

How workshops diagnose DCRI107640 faults

Run a comparative leak-off (back-leak) test across all injectors before condemning a single unit. Compare requested vs actual rail pressure in live data at idle and under load. Inspect injector connectors and wiring before replacing hardware. Never condemn a common-rail injector on a fault code alone.

How every unit is tested before despatch

Each remanufactured DCRI107640 is fully stripped, ultrasonically cleaned and inspected; worn components are replaced with OE-grade parts. The rebuilt unit is calibrated on a common-rail test bench against the manufacturer's specification — delivery, back-leak and response verified — and despatched with a 12-month parts warranty and its calibration data on file.

OE & cross-references

DCRI107640 cross-references 16 further OE numbers, including 095000-7640, 0950007640, 23670-0R170, 236700R170, 23670-0R120, 236700R120, 23670-0R070 and 236700R070. Always match the reference etched on your failed unit's body.
