The fault code of Honda crv is p0 172. What should I do if the fuel system is too thick?

Vehicle fault code p0 172 refers to poor fuel correction (mixing ratio), which can focus on checking fuel pressure, whether the intake system is leaking or blocked, whether the sensor for detecting the intake volume of the intake system is damaged, and whether the fuel quality is poor. ?

P0 172 A set of automobile fault codes is that the mixed steam is too thick.

Fault code p0 172 A group of mixed steam is too thick, indicating that the oxygen sensor detects too little oxygen (too much gasoline) in the tail gas.

Solution: Clean the throttle, replace the filter or the oxygen sensor is faulty.

Extended data:

Fault is an event that the function of some components in the system fails, which leads to the deterioration of the whole system function. Equipment failure generally has five basic characteristics: propagation, uncontrollable, delay, uncertainty and so on.

Fault diagnosis is the process of finding equipment or system faults. A program used to check faults is called a diagnostic program, and a system that performs diagnosis on other devices or systems is called a diagnostic system.

Poor idle speed may be caused by unstable idle speed, engine jitter, high idle speed exceeding the prescribed upper limit, low idle speed lower than the prescribed lower limit or soft idle speed. These phenomena are related to the failure or poor work of oxygen sensor, air flow sensor and exhaust gas recirculation valve, such as poor connection between control circuit and vacuum tube.
