Oxygen sensor set for Toyota Crown and Mark X, covering OEM numbers 89465-0N040, 89465-30710, 89465-0N020 and others; installed on the exhaust manifold or pipe. Real-time monitoring of exhaust oxygen content and feeding signals to ECU to precisely control air-fuel ratio for efficient combustion and emissions compliance.

If the engine check light is on constantly, idle is unstable, fuel consumption is significantly increased, or acceleration is weak, sensor aging or failure is the cause; replacing this kit resolves the issue.
