If You have a check engine light turn on in Your Dodge Grand Caravan the first thing You should do is stop driving as soon as possible. Continuing to drive when You have a check engine light can cause more damage to Your vehicle. When You are stopped You can use an OBD II scan tool on Your car to read the code that is stored in the ECU. If You have a code P219A that means that the sensor has found an air to fuel imbalance on bank 1. This can mean a number of things. It could either be a problem with an O2 sensor, or an injector or valve problem that is not letting air mix properly.
