High-Accuracy Piezoresistive Boost Pressure Sensor with Direct Fitment for 6UZ1, 6HK1, 6WG1 and DENSO OE Compatibility

High-quality boost pressure sensor designed for ISUZU FRR vehicles with 6UZ1 engines, manufactured to strict OEM specifications for reliable performance and direct fitment.

• OE Quality Standard: Manufactured to strict ISUZU technical drawing specifications (1-80220014‑0/‑1), selected to support full 3‑wire 0.5-4.5 V linear output for the 6UZ1 common‑rail ECU.
• High‑Accuracy Piezoresistive Element: Provides a fast, linear response to variable turbocharger boost - essential for the VNT turbocharger vane servo control on 6UZ1 engines.
• Direct Fitment for 6UZ1, 6HK1, 6WG1: Installs directly into the intake manifold post‑intercooler, with exact M12 × 1.25 thread and integral flange to match factory sensors.
• Plays Direct Role in VNT Turbo & EGR Strategy: The ECU uses the MAN sensor value as the lead input for boost pressure control; any offset causes over‑boost, under‑boost or failed DPF regeneration.
• Fixes Multiple Driveability Complaints: Accurate sensor signal resolves P0235 (circuit malfunction), P0236 (performance/range), P0237/P0238 (low/high input), along with black smoke, poor power, heavy fuel consumption and turbo surging.
• Prevents Consequential Component Damage: A faulty sensor can lock the turbo in full‑boost mode, leading to excessive exhaust temperatures, rapid deterioration of the turbocharger and eventually head gasket failure.
• DENSO OE Manufacturer Compatibility: Fully interchangeable with DENSO 079800‑5550, 079800‑5551, 079800‑5552 and 079800‑5553.
• Broad Aftermarket Support: Listed by Hitachi construction equipment OE catalogues under parts 4640533, 4648036 and YA00002566, simplifying bulk ordering for mixed heavy‑duty fleets.
• Designed for Commercial Life: Robust PBT/PA66 housing and sealed terminals withstand high vibration, daily thermal cycling and oil mist contamination in both truck and off‑road applications.
• Direct Bolt‑On Installation: Swaps out in minutes with a 17 mm wrench and basic hand tools - no modifications or recalibration required.

• Material Verification: Ensures metal brackets meet strength and corrosion-resistance standards.
• Damping Element Testing: Confirms proper elasticity and fluid integrity (where applicable).
• Dimensional Accuracy: Verified against OE specifications for precise fit.
• Visual Inspection: 100% checked for cracks, defects, or manufacturing imperfections.
• Packaged Safely: Protected to prevent damage during transit.
