What is the reason for the flashing R yellow light in HOWO?

[DeBrooke]

Here are the specific reasons for the flashing R yellow light in HOWO: 1. False fault: The fault code is reported, but the operation is normal. It may be due to an operation that exceeds the control range of the computer, and the computer feedbacks the fault code. You can eliminate it first and then check whether the fault code still appears. 2. Intake pressure sensor fault: There is no particularly obvious fault in the engine. According to the computer detection information and further inspection, it is found whether there is a fault, which does not affect normal driving or has little impact, but it needs to be discovered and solved in time. For example, intake pressure sensor fault, etc. 3. Oxygen sensor fault: Such faults can be felt through visual inspection and driving experience, and seriously affect the normal operation of the engine, requiring immediate repair. For example, the engine is obviously underpowered, which is likely to be an oxygen sensor problem, etc.
