The Multiquip EM20128 Oxygen Sensor is a genuine OEM component designed for C30HDGA and LS300G concrete pump models. Sourced directly from Multiquip, this sensor meets the exact specifications required for proper engine management on compatible equipment. Confirm your model code before ordering to ensure a direct, accurate fit for your machine.
Key Features
- Genuine OEM Sensor Accuracy — Manufactured to the exact output signal specifications required by the engine control system, ensuring the air-fuel mixture is read and adjusted correctly.
- Direct Drop-In Replacement — Engineered to match the original connector, thread pitch, and sensor body dimensions for straightforward installation without additional hardware.
- Confirmed Fitment — Compatible with Multiquip C30HDGA and LS300G concrete pump models; verify your model code prior to ordering.
- Engine Efficiency Protection — A properly functioning oxygen sensor keeps combustion running within the correct parameters, preventing rich or lean conditions that can damage the engine over time.
- Emissions and Compliance Integrity — Replacing a failed oxygen sensor with a genuine OEM unit helps maintain proper exhaust emissions output, keeping your equipment within operational compliance requirements.
The oxygen sensor monitors the level of unburned oxygen in the exhaust stream and sends a continuous voltage signal to the engine control unit, which uses that data to regulate the fuel-to-air ratio. When the sensor fails or delivers an inaccurate reading, the engine may run too rich or too lean, leading to increased fuel consumption, rough operation, or potential engine damage. Replacing a worn or faulty sensor with the correct OEM unit restores accurate combustion feedback and keeps the engine performing as intended.
