DOC Inlet Pressure Sensor
Detroit Diesel

This inlet pressure sensor for the DOC system accurately measures intake manifold pressure, providing critical input for emissions control and fuel regulation. Its compact design features a stainless steel housing resistant to corrosive exhaust gases and high temperatures, ensuring durability over time. Operating within a range of -10°C to +125°C, it maintains precise readings even under severe thermal conditions. The sensor operates on a 5 VDC supply and has a 100-ohm impedance, supporting reliable communication with engine control modules. Its performance characteristics, including a burst pressure of nearly 40 psi, allow it to withstand pressure transients typical in heavy-duty engine operation. Proper inlet pressure monitoring is essential for optimizing catalyst performance, reducing emissions, and ensuring efficient combustion. Source One Parts Center offers this sensor as part of their comprehensive inventory, supporting reliable engine management and compliance.
