Products Description
The 3810020B29D is a pressure sensor for FAW J6/J7 trucks, a core detection part of the vehicle's electronic control system. It monitors oil/fuel/air pressure in real time, sends signals to the ECU, and triggers alarms for abnormal pressure. We've sold it to 30+ repair shops and fleets for 5 years-users say it's steady: no signal drift, no false alarm, no damage, no measurement error.
It has a ceramic pressure chip (±1% FS accuracy), stainless steel diaphragm, and high-temperature plastic housing. Internal circuit is waterproof-coated, connector is gold-plated for stable signals. -40℃ to 125℃, 2000Hz vibration, oil/fuel corrosion-none mess it up. It detects 0-1.6MPa pressure with ≤10ms response, protecting the engine. Fits FAW J6/J7's original ports perfect: screw in and plug the harness, no calibration needed. We test accuracy, vibration resistance and service life, so it's reliable.
Features And Advantages
① High precision & fast response: ±1% FS accuracy captures tiny pressure changes; ≤10ms response avoids alarm delay.
② Strong adaptability: Works in -40℃ to 125℃; resists 2000Hz vibration, no signal drift.
③ Corrosion-resistant & durable: Stainless steel diaphragm resists oil/fuel; gold-plated connector avoids rust; lasts ≥5 years.
④ Fits FAW fast: Thread, connector and signal match original. ECU recognizes it directly, saves maintenance time.
Application Scope
Only FAW J6/J7 (oil/fuel/air pressure monitoring). No old FAW J5, HOWO, SHACMAN-different specs cause failure or false alarm.

FAQ
Q1: Fits old FAW J5, HOWO, or SHACMAN?
A1: No, only J6/J7.
Q2: No display, false alarm, or signal fluctuation?
A2: Check connector tightness and mounting position first.
