O2 Sensor – CR152106

An oxygen sensor for Crown internal combustion lift trucks, this component measures the oxygen content in the engine's exhaust stream and reports it to the fuel management system. That feedback lets the engine controls trim the air-fuel mixture in real time, supporting clean combustion, steady running, and controlled emissions across the truck's operating range. Mounted in the exhaust path, the sensor works in high heat and must respond quickly for accurate mixture correction. A fresh sensor restores reliable readings when an aging one drifts, slows, or triggers running and emissions faults. Confirm the connector, thread, and engine application match the sensor being replaced.
