The Causes Of Noise Generation in Oxygen Sensors

The clutter of oxygen sensor signals is usually caused by the following reasons:
A. Poor ignition of the cylinder (various root causes, ignition system caused by poor ignition, cylinder pressure caused by poor ignition, vacuum leakage, and fuel injector imbalance caused by poor ignition);
B. System design, such as different intake pipe channel lengths, etc;
C. The expansion of system design issues caused by aging of engines and components (the expansion of different intake pipe channel lengths caused by imbalanced cylinder pressure);
D. System design, such as different intake duct channels.
