What are the effects of not clearing car trouble codes?
2 Answers
If the fault is repaired but the trouble code is not cleared, it will not affect the vehicle's operational performance. Extended methods for handling car faults are as follows: 1. For automatic transmission vehicles experiencing stalling, the main cause is the use of low-quality fuel. Refueling with high-grade fuel at reputable, larger gas stations can ensure a longer lifespan for your car and better performance while driving. 2. For stalling issues in idle mode, the primary cause is excessive dust in the air, leading to deposits of dirt on the idle motor valve core and throttle body. When too much dirt accumulates, the engine may experience low idle speed, unstable idle conditions, or stalling while driving. Cleaning the idle motor can resolve this issue.
Having driven for many years, I deeply understand the significant impact of not clearing fault codes. Firstly, that annoying check engine light stays on, not only distracting but also potentially causing you to overlook new issues over time. For instance, once my car's fuel consumption suddenly increased because unresolved fault codes masked a clogged fuel line. Secondly, the vehicle may enter a safety mode automatically, resulting in slower acceleration, difficulty climbing hills, and increased breakdown risks. Additionally, emissions tests during annual inspections often fail, requiring costly retests—what a waste. Long-term neglect can worsen minor issues like carbon buildup or sensor failures, leading to skyrocketing repair costs. I recommend developing the habit of clearing codes promptly after repairs or using an OBD tool to handle it—ensuring peace of mind and safety.
