When you see the Engine Light ON or the Service Engine Soon Warning Light, it could be indicating a fault code of p1211. This code typically points to an issue with the fuel injector control module performance.

It means that the fuel injector control module is not functioning as it should, which can lead to various problems with the fuel system. The p1211 fault code can cause symptoms such as rough idling, poor acceleration, and even stalling of the engine. You may also experience a decrease in fuel efficiency and overall engine performance.

Ignoring this fault code can lead to further damage to the fuel system and potentially more expensive repairs down the line. To fix the p1211 fault code, it is recommended to first check the wiring and connections related to the fuel injector control module. Any loose or damaged connections should be repaired or replaced. If the wiring and connections are in good condition, then the fuel injector control module itself may need to be replaced.

It is important to address this issue promptly to ensure optimal engine performance and avoid any further complications.
