Description
Product Overview
The 3843012 integrated pressure and temperature sensor is installed in the intake manifold and collects two sets of signals - intake pressure and intake temperature - which are then transmitted to the electronic control unit. This precisely matches the fuel injection volume and ignition / fuel injection timing. Old sensors may experience drift in sensing, aging seals, and water ingress into the connector, causing signal distortion, resulting in decreased power and increased fuel consumption. Replacing this product will restore precise engine control and is suitable for light trucks, passenger cars, small construction machinery, and agricultural diesel equipment maintenance and replacement.
Unique Core Features of the Single Product
Double brass bushing flange base, ensuring stable and non-offset installation
Integrated triangular flange by injection molding, with brass metal sleeves embedded in the two mounting holes, and the bolts locking firmly without slippage. The sensor will not loosen or shift under long-term vibration conditions, avoiding fluctuations in the collected signals.
Integrated temperature and pressure sensing probe, simultaneously collecting dual data
Central integrated sensing needle, with a pressure sensing chip and temperature thermistor element integrated internally. A single probe reads both intake pressure and temperature, and the signals are transmitted synchronously, reducing the need for separate sensor installations and simplifying the cabin pipe layout.
Blue ring-shaped oil-resistant sealing gasket, double-layer dustproof and waterproof
The probe root is equipped with a ring-shaped rubber sealing ring, which fills the gap between the probe and the manifold after assembly, preventing intake gas leakage, water, gasoline, and dirt from seeping into the internal chip, and eliminating signal short circuits and data drift.
Integrated sealed direct plug for the electronic control unit, resistant to oil and heat
The tail has an all-black plastic-sealed snap plug with a multi-layer internal sealing structure, isolating the cabin from high temperatures, dust, and diesel oil contamination. The contact points remain stable under bumpy driving conditions, and there are no signal error reports.
High-temperature resistant composite engineering plastic housing, resistant to aging and deformation
The shell is made of modified plastic resistant to high and low temperatures, which does not crack or deform under alternating cold and hot conditions. The built-in sensing chip is treated for anti-electromagnetic shielding to isolate engine circuit electromagnetic interference, ensuring accurate and stable data collection. Applicable scenarios
Suitable for light-duty diesel pickup trucks, box vans, diesel passenger cars, small excavators, agricultural tractors. It is applicable for urban commuting, high and low temperature conditions in fields and construction sites, as well as light-load operations in dusty and multi-polluted environments.
