P0134 – O2 Sensor Circuit No Activity Detected Sensor 1 Bank 1: The front heated oxygen sensor (or O2 sensor 1) is placed into the exhaust manifold. It detects the amount of oxygen in the exhaust gas ...

Last month, we kicked this series off by showing you how to save some money by diagnosing a bad MAP sensor rather than just chucking cash at new parts that may or may not fix a specific problem. This ...

This MCU-based circuit converts sensor outputs, which are often voltage, into a standard current signal, thus avoiding noise and loss when sending over long lines. When taking measurements from analog ...
