P120B Fault Code: Understanding The Description And Troubleshooting Tips
The P120B fault code is related to the Secondary Fuel Injector Bank 1 in the automobile’s Powertrain Control Module (PCM). The PCM is responsible for monitoring the fuel injector’s performance. When the Secondary Fuel Injector Bank 1 does not meet the factory specifications, the PCM triggers the P120B code.
This code indicates that there is excessive flow in the Secondary Fuel Injector Bank 1.
In simpler terms, the P120B fault code means that there is an issue with the fuel injector in the automobile’s engine. Specifically, the fuel injector in the Secondary Fuel Injector Bank 1 is allowing too much fuel to flow.
This can lead to various problems, such as decreased fuel efficiency and engine performance issues.
It is important to address this issue promptly to avoid further damage to the engine and ensure optimal vehicle performance.
