What does "I/M Readiness" indicate on a scanner in Ford vehicles?

"I/M Readiness" on a scanner in Ford vehicles indicates the state of emission-related monitors. This feature is crucial for determining whether the vehicle's emissions systems are functioning correctly and whether they are ready for inspection. If the monitors are "ready," it means that the vehicle has completed its self-diagnostic checks, and the emissions systems are operating as intended.

This is especially important for emissions testing, as regulatory compliance requires that certain monitors be in a "ready" state to ensure that the vehicle meets environmental standards. The various monitors track components like the catalytic converter and the oxygen sensors, helping to ensure that the vehicle minimizes harmful emissions.

Understanding I/M Readiness is essential for diagnosing potential issues related to emissions systems and ensuring that the vehicle is roadworthy and compliant with emission regulations.
