What are the causes of the Toyota P1604 trouble code?

The main causes of the P1604 trouble code are the following two points: 1. When the car's throttle is stuck or there is insufficient oil pressure, causing the vehicle to fail to start successfully; 2. After the car's battery cable has been disconnected, the Toyota vehicle cannot start on the first attempt. Relevant information about car faults is as follows: 1. A car fault refers to the phenomenon where the car's system, assembly, and components or the entire vehicle lose their specified functions. 2. Based on the severity and relevance of the fault's impact on car performance, faults are classified into four categories: critical faults, which endanger driving safety, cause casualties, result in the scrapping of major assemblies, significant economic losses, or severe harm to the surrounding environment.
I've been driving for many years and encountered the Toyota P1604 trouble code several times. This is usually caused by abnormal start signals, such as an aging battery with insufficient power or issues with the starter itself leading to poor signal transmission. Once, my car struggled to start, cranking for a long time without firing up, and the code reader showed P1604. Upon inspection, I found the battery terminals were corroded, causing poor contact. It's crucial to address this promptly; delaying might result in a complete failure to start, affecting daily commutes. I recommend first trying to tighten the connections or test the battery voltage yourself. If that doesn't work, take it to a repair shop. Additionally, Toyota's starting system is quite sensitive, and this issue often occurs after rainy days. That's why I always remind my friends to maintain their batteries regularly and clean the wiring, which can save a lot of hassle.
