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 ...
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 ...
