The Genie 88450GT is a genuine OEM Oxygen Sensor LRG425EFI designed for a wide range of Genie telescopic boom lifts, articulating boom lifts, and scissor lifts. As a direct OEM replacement, this sensor is built to the same specification as the original, ensuring correct fit and signal output for the engine management system it serves. Compatibility spans S-series telescopic booms including the S-40, S-45, S-60, S-60 XC, S-60 HC, S-60 TRAX, S-65, and S-65 TRAX; Z-series articulating booms including the Z-45/25, Z-45/25J IC Power, Z-45/25 IC, Z-45/25J IC, Z-60/34, and Z-80/60; and GS scissor lifts including the GS-3384, GS-3390, GS-4390, and GS-5390. Always cross-reference part number 88450GT against your machine's parts manual to confirm it is the correct sensor for your unit's engine configuration before ordering.
Key Features
- Genuine OEM Sensor Grade — Sourced directly from Genie, this oxygen sensor meets the original output and calibration specification required by the LRG425EFI engine, ensuring accurate readings that the engine management system depends on.
- Direct OEM Replacement — Engineered to the same connector type, thread pitch, and dimensions as the original sensor, this part installs in place of the factory unit without modification.
- Broad Genie Equipment Fitment — Fits multiple Genie S-series telescopic booms, Z-series articulating booms, and GS rough-terrain scissor lifts across the LRG425EFI engine platform.
- Engine Efficiency Maintained — A properly functioning oxygen sensor keeps the engine's air-fuel mixture within the correct operating range. A failed or degraded sensor can cause rough running, increased fuel consumption, and fault codes that take the machine out of service.
- Emissions System Integrity — On LRG425EFI-powered equipment, the oxygen sensor is a functional part of emissions compliance. Replacing a faulty sensor with the correct OEM part restores proper engine operation and supports regulatory compliance requirements on regulated jobsites.
An oxygen sensor monitors the level of oxygen in the engine's exhaust stream and sends a continuous signal to the engine control unit, which uses that information to adjust the fuel-air mixture for efficient combustion. On Genie equipment powered by the LRG425EFI engine, a worn or failed oxygen sensor can trigger fault codes, cause the engine to run rich or lean, and ultimately lead to increased fuel use or an engine shutdown that halts the machine. Replacing the sensor with the correct OEM part restores accurate feedback to the engine management system and returns the machine to normal operation.
