The Genie 215309GT Knock Sensor is a genuine OEM component built for a wide range of Genie telescopic boom lifts, articulating boom lifts, and scissor lifts, including S-60, S-65, Z-60/34, Z-62/40, Z-45/25, Z-45/25J IC Power, Z-45 XC, GS-3384, GS-3390, GS-4390, GS-5390, and related XC, TRAX, HF, and HC variants. Sourced directly from Genie, this sensor carries full OEM part status — correct specification, correct fitment, no guesswork. Cross-reference part number 215309GT against your machine's parts manual to confirm it is the right sensor for your specific unit before ordering.
Key Features
- Genuine OEM Specification — Manufactured to Genie OEM standards, this knock sensor meets the exact output and sensitivity tolerances required for correct engine management on the machines it serves.
- Direct OEM Replacement — Designed to install in the same location as the original sensor, connecting to the existing wiring harness without adaptation.
- Broad Fitment Across Genie Families — Fits Genie S-series telescopic booms, Z-series articulating booms, and GS-series scissor lifts, covering XC, TRAX, HF, and HC variants across multiple configurations.
- Engine Protection Maintained — A functioning knock sensor allows the engine control system to detect abnormal combustion and adjust timing accordingly. A failed sensor removes that protection, leaving the engine exposed to damage and potentially triggering fault codes that take the machine out of service.
- Operational Compliance — On aerial work platforms, engine faults caused by a failed knock sensor can prevent the machine from operating safely. Replacing a failed sensor with a correct OEM unit restores the engine management system to its intended operating state.
A knock sensor monitors the engine for detonation — the uncontrolled combustion that produces a characteristic knocking or pinging sound under load. When the sensor detects knock, it sends a signal to the engine control module, which retards ignition timing to bring combustion back within safe limits. Without a properly functioning sensor, the engine control system operates blind to detonation events, which over time can cause internal engine damage. On Genie boom lifts and scissor lifts that depend on reliable engine output to power platform and drive functions, keeping this sensor in good working order is a straightforward part of sound engine maintenance.
