Why is the voltage of the atmospheric pressure sensor of JAC Ruifeng S5 low?

The reasons for the low voltage of the JAC Ruifeng S5 atmospheric pressure sensor are as follows:

1. The continuous low voltage signal indicates that the mixture is too lean, the oxygen sensor itself is faulty, etc.

2. The fuel injector is clogged. The clogged fuel injector nozzle hole will lead to too little fuel injection in individual cylinders, causing the mixture to be too lean.

3. The internal circuit of the sensor is open or short-circuited.
