If you think your vehicle has fuel pump circuit issues, you might be able to use an OBD-II scanner to check whether a diagnostic trouble code (DTC) has been triggered. If the P0232 code has been set, read this article to learn about its definition, common symptoms, and possible causes.

What Does the P0232 Code Mean?

Diagnostic trouble code (DTC) P0232 code stands for “fuel pump secondary circuit high.” The P0232 code is triggered when the powertrain control module (PCM) detects an incorrect signal from the fuel pump.

The P0232 code is triggered when the PCM detects an incorrect signal from the fuel pump.

The fuel pump is responsible for transferring fuel from the fuel tank into the fuel injectors located at the engine. The engine needs a consistent flow of fuel, or else it will either sputter or stall. If the PCM receives a high-voltage signal from the fuel pump circuit even when the fuel pump relay isn’t activated, it may trigger the P0232 code.

Note: The definition of the P0232 code can be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.

What are the Common Causes of the P0232 Code?

There are many ways to fix a specific OBD-II code because there are many possible causes. Once you’ve identified the cause of the trouble code, then you can consult reliable online auto repair resources and how-to guides for possible fixes.

Since all vehicles are different, a fix for an OBD-II code for one vehicle may not work for another. Internal components can vary greatly among manufacturers. This is why you should consult a repair manual or repair database when it comes to troubleshooting and repairing DTCs. Chilton repair manuals can be useful. However, an ALLDATA DIY subscription might be better, as it provides detailed factory repair information for drivers who want to do the repairs themselves.
