The DENSO 295900-0190 is an original common rail fuel injector designed for the Toyota 11 Series platform, serving as a direct OEM replacement for part numbers 23670-0L050, 23670-30400, 23670-09330, and additional cross-references within the 23670 Series. It is engineered for Toyota diesel engines including the 1KD-FTV 3.0L turbo diesel and 2KD-FTV 2.5L turbo diesel, both operating within the D-4D common rail fuel system. The injector is compatible with Euro III and Euro IV emission configurations, ensuring broad coverage across Toyota commercial and passenger diesel applications.

This injector incorporates high precision machining that improves injection accuracy, combined with a multi-hole nozzle design that enhances fuel atomization for more efficient combustion. Wear resistant internal components and corrosion resistant surface treatments extend the service life of the assembly, while OEM calibration ensures stable idle operation, reduced engine vibration, and precise fuel metering. The high pressure capability of the injector supports demanding commercial use, delivering lower fuel consumption and reduced particulate emissions to meet modern diesel performance expectations.

Proper maintenance of the 295900-0190 requires the use of high-quality diesel fuel, immediate replacement of contaminated fuel filters, and regular draining of water separators. During installation, technicians should clean the injector bore, install a new sealing washer, verify injector coding, and conduct post-installation diagnostics including rail pressure verification and return flow testing. Common fault indications include internal leakage, nozzle wear, solenoid malfunction, carbon deposits, return flow imbalance, and fuel contamination damage, all of which can be identified through injector balance testing and return flow deviation monitoring.
