8-97359985-2 Isuzu CVR / FRD / NPR Engine DPF Differential Pressure Sensor

Product Title

8-97359985-2 Isuzu Engine DPF Differential Pressure Sensor
(Part Number: 8-97359985-2, OEM reference)

Applicable Models

• Engines equipped with DPF aftertreatment systems, e.g., Isuzu 4HK1, 6HK1

• Also suitable for other construction machinery or buses using the same platform (verify original sensor part number before installation)

Product Overview

This sensor is a core component of the diesel aftertreatment system, measuring the pressure difference between the inlet and outlet of the DPF. The ECU uses this differential pressure signal to estimate soot loading and trigger active regeneration or cleaning alerts. Accurate pressure detection ensures emissions compliance, reduces fuel consumption, and extends DPF service life.

Features & Benefits

• High‑precision sensing element: Utilises ceramic or MEMS differential pressure chip with excellent linearity and fast response.

• High‑temperature & corrosion resistance: Housing and seals withstand high exhaust temperatures and acidic condensate in harsh environments.

• OEM‑spec design: Interface dimensions, electrical connector, and mounting holes match Isuzu original parts – direct plug‑and‑play replacement.

• Vibration‑resistant construction: Built‑in damping reduces signal interference from engine vibration.

• 100% tested: Each unit is pressure‑calibrated and leak‑tested before shipment for long‑term reliability.

Quality Assurance

• Manufactured under ISO 9001 and IATF 16949 quality systems

• 100% functional and leak‑tested prior to dispatch
