Dodge Caliber PCM issue causing engine light to stay on on Dodge Caliber

Some Dodge Caliber owners report experiencing persistent engine lights due to various PCM-related issues. These issues can arise from a failed PCM replacement, which may keep the engine light illuminated even when the engine appears to be running fine. Additionally, some owners find that the Check Engine Light does not reset automatically after a PCM replacement, necessitating a manual reset. A flashing Check Engine Light is another significant concern, indicating serious problems like catastrophic misfires that could damage the catalytic converter. Common reasons for the engine light staying on include failed self-diagnostic cycles and emissions problems, as well as simpler issues like a loose gas cap. It is crucial for owners to address these potential causes promptly to prevent further damage to their vehicles.
