Laymans terms

This code means that there's a problem with the electricity getting to a group of fuel injectors in your car. It's like if a group of lights in your house won't turn on because of a broken wire.

Explanation

The engine control module (ECM) has detected an open circuit or voltage issue in the supply voltage circuit for the fuel injector group C.

Technical description

The P2152 code indicates that the ECM has identified a problem with the supply voltage circuit for the fuel injector group labeled as 'C'. This could be due to an open circuit, poor connection, or a failed component that supplies power to this group of injectors. This can affect the engine's ability to inject fuel properly, leading to performance issues.
