The Genie 52564GT is a genuine OEM O2 Sensor designed for a range of Genie telescopic boom lifts, articulating boom lifts, and scissor lifts. As a direct OEM replacement, this sensor is built to match the original specification, ensuring the engine management system receives accurate exhaust gas readings. Compatible models include the S-60, S-65, S-80, S-85, S-40, S-45, Z-45/22, Z-45/25J IC Power, Z-60/34, GS-3390, GS-4390, and GS-5390 — confirm part number 52564GT against your machine's parts manual to verify fitment for your specific unit.
Key Features
- Genuine OEM Sensor Accuracy — Manufactured to Genie's original specification, this O2 sensor delivers the precise signal output the engine control system requires for correct air-fuel management on LRG 425 EFI-equipped machines.
- Direct OEM Replacement — Engineered to install into the existing sensor port using the original hardware and connector, this sensor slots in without adaptation.
- Broad Genie Fitment — Fits a wide range of Genie S-series telescopic booms, Z-series articulating booms, and GS scissor lifts equipped with the LRG 425 EFI engine. Cross-reference 52564GT against your parts manual before ordering.
- Supports Correct Engine Performance — A functioning O2 sensor allows the EFI system to maintain the correct fuel mixture. A failed or degraded sensor can cause rough running, increased fuel consumption, and fault codes that take the machine out of service.
- Emissions and Engine Control Compliance — On EFI-equipped aerial lifts, a correctly functioning O2 sensor is integral to the engine's emissions control loop. Using the genuine OEM part maintains the integrity of the factory engine management system.
An oxygen sensor monitors the concentration of oxygen in the exhaust stream and sends a continuous signal to the engine's electronic fuel injection system. The EFI controller uses that signal to adjust the fuel mixture in real time, keeping combustion efficient and the engine running cleanly. When the sensor degrades or fails, the controller loses that feedback, leading to a rich or lean mixture, rough idling, elevated fuel use, and triggered fault codes — any of which can ground the machine until the fault is resolved. Replacing a worn sensor with the correct OEM part, such as the 52564GT, restores the closed-loop feedback the engine needs to run at its designed performance level.
