NHTSA Complaint #11646443 — 2007 HONDA ACCORD

Electrical component malfunctioning Knock Sensor: code error: p0325 I noticed my check engine light had came on but wasn't on for long and had turned off on the dash. A few weeks later the check engine light reappeared and did not go back off. Upon this happening I noticed a major difference in my vehicle performance. The fuel consumption had significantly increased, I recognized these shake like vibrations when sitting in park or at a complete stop. A "knocking noise" I would hear coming from the engine, as well as rough idling almost as if there was a "stalling/hesitant" idling that sounded very off. Adding a very noticeable reduced power from the engine that was not there when the check engine light was not on. This has been a confirmed malfunction and should be replaced due to the importance the knock sensor provides to the engine of this vehicle. This was confirmed by an employee at a parts store, with there computer code reader. Upon request for inspection; I have open availability. Confirmed: March 4, 2025 The additional code provided also stated the catalytic converter is recommended to be replaced as well. Engine related systems that power the vehicle such as (catalyst pipes) Powertrain (previously recalled prior time frame) due to this being a numerously reported issue with many other owners of this same vehicle I own. There is a reoccurring issue that absolutely goes hand in hand with the performance and job of the also stated ongoing problems I'm facing. The knock sensor is a vital part to the powertrain system that helps optimize engine performance and protects it from harmful knocking by monitoring combustion irregularities. Potentially if these are current issues, and have caused any kind of damage, the damage alone effects as follows: -wiring issues, internal malfunction, physical damage , corrosion from exposure to engine fluids, internal short circuit, mechanical damage, faulty wiring,excessive vibrations, wear and tear from use.
