The Multiquip P2561 Oxygen Sensor is a genuine OEM component designed for C30HDNI series Mayco concrete pumps. As a factory-sourced part, it meets the exact specifications of the original sensor installed at the time of manufacture, ensuring proper integration with the engine management system on C30HDNI and C30HDNI Precision models. Sourced directly through authorized Multiquip supply channels, this sensor is the correct replacement when the original unit shows signs of wear, fouling, or failure.
Key Features
- Genuine OEM Accuracy — Factory-matched output signal range ensures the engine control system receives precise exhaust gas readings without calibration adjustments.
- Direct Drop-In Replacement — Engineered to the same connector type, thread pitch, and sensor body dimensions as the original, allowing straightforward installation into the existing exhaust bung.
- Confirmed Fitment — Compatible with C30HDNI and C30HDNI Precision Mayco concrete pump models.
- Engine Efficiency Protection — A functioning oxygen sensor keeps the air-fuel ratio in the correct range; a failed sensor can cause rough running, increased fuel consumption, and elevated emissions.
- Emissions System Compliance — Maintaining a correctly functioning oxygen sensor supports proper combustion management and helps keep the engine within its designed emissions operating parameters.
The oxygen sensor monitors the concentration of oxygen in the exhaust stream and sends a continuous signal to the engine control unit, which uses that data to adjust the fuel-air mixture in real time. When the sensor degrades or fails, the engine loses the feedback it needs to regulate combustion efficiently, which can result in poor throttle response, increased fuel use, and the engine running excessively rich or lean. Replacing a worn sensor with a genuine Multiquip P2561 restores accurate closed-loop control and keeps the engine performing as intended.
