OBD-II Trouble Code Description for P0232 Citroen
Fuel Pump Secondary Circuit High
What does this mean?
OBD2 Code P0232 Citroen definition:
The fuel pump is powered by the fuel pump relay. When the PCM (powertrain control module) activates the fuel pump relay, voltage is supplied to the fuel pump and it pressurizes the fuel system. Some vehicles have a feedback on the fuel pump supply circuit. This is simply a circuit spliced into the voltage feed to the fuel pump. The splice is usually located close to the PCM. The PCM monitors this feedback circuit to ensure that there is proper voltage being sent to the fuel pump. As it activates the fuel pump relay, it expects to see battery voltage on the feedback circuit. If the PCM sees an unexpected high voltage when the fuel pump isn’t activated, P0232 Citroen may set.
Symptoms
Possible sumptoms of OBD code P0232 Citroen
Symptoms of a P0232 Citroen DTC may include: MIL (malfunction indicator lamp) illumination Fuel pump runs with key off Small amount of voltage present on FP (fuel pump) voltage supply circuit due to short
Causes
Possible causes of OBD code P0232 Citroen
Potential causes of a P0232 Citroen code include: Bad FP relay Short to voltage on FP voltage supply circuit or feedback circuit Short to ground on PCM FP relay control circuit PCM FP relay control driver shorted to ground internally
Possible Solutions
It is possible with a P0232 Citroen for the fuel pump to be running continuously, even with the ignition off. If that’s the case and you can hear the fuel pump running, you may be able to disregard some of the following checks. Turn the KOEO (key on engine off) and wait for a few seconds. This allows the PCM to complete it’s fuel pump pre-cycle. Now, using your scan tool (if you have one) observe the FP VOLTAGE FEEDBACK reading in the datastream. This reading indicates what kind of voltage the fuel pump is receiving. If you don’t have access to a scan tool, use a voltmeter to read the FP voltage at the fuel tank. If your reading shows any voltage at all present to the fuel pump with KOEO (or if you can hear the pump running), remove the FP relay. If the voltage remains, or the fuel pump continues to run, then there is a short to voltage on the FP voltage supply circuit or on the feedback circuit. Repair as necessary. If the voltage disappears (or the pump quits running) with the FP relay removed then try replacing the relay with a spare one. Upon reinstalling the spare relay, if the voltage disappears, the relay was faulty due to a short. If, though, after replacing the relay voltage is still present, suspect that the PCM FP relay control circuit is shorted to ground. Check for a short to ground on the PCM FP relay control (ground driver) circuit by removing the FP relay and ohm between a good ground and the PCM FP relay control. There should be no continuity to ground with KOEO (after the FP pre-cycle is completed). If there is continuity to ground the wire is shorted. Find the short to ground and repair as necessary. If you can find no physical short, It may be necessary to snip the FP relay control wire close to the PCM connector where it will be easy to repair and check for continuity to ground with KOEO coming OUT of the PCM. If there is no continuity the wire is shorted in the harness. But if continuity exists, the driver may be internally shorted to ground and the PCM may require replacement.

Note:
1. The list of automotive Makes at the right edge of the screen. The currently selected ODB-ii codes is for the Citroen makes.
2. Look up the other OBD II Trouble Codes, please use the search box. Enter the 5 character trouble codes in the search box and submit the search.
3. Don’t assume a particular OBD-II code means the same for other auto manufacturers as there are many makes specific codes in use.
4. If your OBD-II trouble codes are for a different car, select that vehicle series before searching for the diagnostic codes because not all OBD2 codes used by one manufacture are used by the other makes.
