1611704 Air Pressure Sensor — Cat 120K 12H

This is an air pressure sensor that monitors intake manifold or boost pressure and sends this data to the engine control unit (ECU). It is manufactured to meet high-quality standards, providing accurate readings unlike a faulty sensor which can drift or fail. Symptoms of a failing sensor include loss of engine power, increased fuel consumption, and illuminated check engine lights.

Installation & Application Notes

Disconnect main battery before working on electrical components. Use dielectric grease on all connector pins. Check ground connections — most electrical faults trace to poor grounds. Test with multimeter before installing new parts.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The initial symptom is often a noticeable reduction in engine power or sluggish acceleration. If ignored, the engine may run rough, experience increased exhaust smoke, and trigger diagnostic trouble codes related to boost pressure. Prolonged operation with a faulty sensor can lead to inefficient combustion and potential engine damage.

Installation Tip

Ensure the sensor port is clean and free of debris before installing the new sensor. Avoid using excessive force when threading the sensor into its port, as this can damage the threads.

Service Note

Inspect the air intake hoses and intercooler for leaks or damage when replacing the air pressure sensor.
