Denso 499000-6121 Fuel Rail Pressure Sensor

The Denso 499000-6121 is a high-pressure common rail fuel pressure sensor designed for Toyota 2AD-FTV 2.2L diesel engines. It measures fuel pressure within the rail up to 200 MPa and transmits a voltage signal to the ECU for precise injection control. The sensor features a 3-pin electrical connector and a threaded mounting interface compatible with the OEM fuel rail assembly. This component replaces Toyota OEM part numbers 89458-71010 and 89858-71010. It is engineered for direct fitment on applications including Toyota Hilux, Innova, Avensis, Hiace, and RAV4 models equipped with the 2AD-FTV engine. The sensor housing is constructed from high-strength stainless steel to withstand extreme fuel pressures and thermal cycling in heavy-duty operating conditions.
