Product Description
5698455 Intake Pressure & Temperature Sensor is a combined TMAP sensor mounted on the intake manifold of Cum-mins B4.0 engine. It simultaneously captures real-time air pressure and intake air temperature signals and feeds this data back to ECU, so the control unit can adjust fuel injection quantity and boost strategy accurately. This aftermarket replacement sensor resolves unstable idle, weak acceleration, increased fuel consumption and active fault codes triggered by signal drift, internal circuit breakage and probe contamination of aged sensors. Precise signal feedback helps maintain optimized combustion efficiency and cuts emission-related failure risks for medium-duty delivery trucks.
Product Advantages Adopts high-precision pressure sensing chip with stable output under fluctuating boost pressure. The temperature probe responds quickly to intake air changes and resists soot adhesion. Reinforced sealed plastic housing withstands engine vibration and intake pipe thermal cycling. Every sensor undergoes signal calibration and aging screening before shipment, 4-pin plug matches original wiring harness for direct installation.

FAQ
Q1: What can cause the sensor to send abnormal readings even if the sensor itself is intact?
A1: Leaks on the intake pipeline change manifold pressure and mislead sensor measurement.
Q2: How does carbon soot covering the probe affect sensor performance?
A2: Soot insulation slows temperature response and creates offset between actual and sampled values.
Q3: Why should the technician clear fault codes after finishing sensor replacement?
A3: Historical DTCs remain stored and may mislead judgment even with a functional new sensor.
