무조건 부러진다? 공포의 PM센서 교환하는 법

Additional Notes In any case, it's crucial to avoid using large, long tools. Forcing them loosen increases the risk of damaging the exhaust pipe. Therefore, it's important to be patient and continue heating, even if it takes time. A suitable tool, like the 24mm combination wrench I used, is ideal. It's small enough that even a moderate amount of force won't cause damage. If a PM sensor failure is accompanied by engine or DPF issues, simply replacing the PM sensor alone won't solve the problem. This presents a separate issue.
