The Multiquip 2441805S Oxygen Sensor is a genuine OEM component designed for HTN27K and HTN28K ride-on power trowels. As a direct OEM replacement, part 2441805S is built to the same specifications as the original, ensuring proper integration with the trowel's engine management system. Verified fitment covers the HTN27K and HTN28K models, so you can order with confidence that this sensor will seat and connect correctly. DHS Equipment stocks this part to keep your finishing equipment running at its best.
Key Features
- Genuine OEM Construction — Manufactured to original output tolerances, ensuring the sensor delivers accurate exhaust gas readings the engine control system relies on.
- Direct Connector Match — Engineered to connect directly to the existing wiring harness on HTN27K and HTN28K trowels without splicing or adapter fittings.
- Confirmed Fitment — Verified for HTN27K and HTN28K Whiteman ride-on power trowels; check your model code before ordering.
- Engine Efficiency Protection — A correctly functioning oxygen sensor maintains proper air-fuel ratio, supporting consistent engine output and fuel efficiency during long finishing runs.
- Emissions System Compliance — Correct sensor output is required for the engine to meet its rated emissions performance; a failed sensor can trigger fault codes and affect machine operation.
An oxygen sensor monitors the level of oxygen in the exhaust stream and sends that data to the engine control unit, which uses it to continuously adjust the air-fuel mixture for efficient combustion. When the sensor fails or reads inaccurately, the engine may run rich or lean, leading to increased fuel consumption, rough idling, or fault codes that can take the machine out of service. Replacing a worn sensor with the correct OEM part restores accurate feedback to the engine management system and keeps the trowel performing as intended.
