How to fix P222E code when you experience a sudden loss of engine power or a noticeable smell of raw fuel from your tailpipe. This error code indicates an intermittent fault with your barometric pressure sensor B, which helps your computer maintain a stoichiometric mixture of fourteen point seven parts air to one part fuel. Whether you are driving a GMC, Mazda, or BMW, this sensor is vital for adjusting to changes in altitude and air density. In this guide, I show you how to locate the sensor and inspect it for common issues like heat damage or loose electrical connectors. We walk through the process of using a multimeter to compare your sensor readings against manufacturer specifications. Remember to always disconnect your battery before working on these sensitive components to avoid electrical spikes.
