Default '07 Focus ST - DTC Fault Code P0230-21

Hi all,

Decided to have a look & see if I had any fault codes since having my downpipe (Mongoose) & sports cat (Mountune / Milltek) fitted, so I pluged in my Dreamscience application on my laptop.

I found fault code P0230-21 ( have no idea about the other aswell). I also then put the car back to the standard map & re-ran the diognostic scan & the fault code disapeared.

I found this below from here http://www.fordstown...p?f=101&t=54794 but I have no idea what it means.
P0230 - Fuel Pump Primary Circuit Malfunction NOTE: For natural gas applications, the following description applies to the fuel shutoff valve (FSV) circuit.
The PCM monitors the fuel pump (FP) circuit output from the PCM. The test fails if: With the FP output commanded ON (grounded), excessive current draw is detected on the FP circuit; or with the FP output commanded OFF, voltage is not detected on the FP circuit (the PCM expects to detect VPWR voltage coming through the fuel pump relay coil to the FP circuit). Open or shorted fuel pump (FP) circuit
Open VPWR circuit to fuel pump relay
Damaged fuel pump relay
Damaged PCM
When the FPF PID reads YES, a fault is currently present.
An open circuit or short to ground can only be detected with the fuel pump commanded OFF.
A short to power can only be detected with the fuel pump commanded ON.
During KOEO and KOER self-test, the fuel pump output command will be cycled ON and OFF.
Any ideas what it means & how to fix it? I know that I can just clear it but i'd rather sort it.

The car has been running the DSCi map, K&N panel filter, Airtec Gen3 intercooler & the above for a while with no problems.

Thanks

Andrew

If it aint broke, don't fix it lol. What I'd do is put your map back on there, make sure codes are cleared and use the car. If the code re-appears then investigate further but for now I wouldn't worry.

Thanks.

Also, the the 'Distance to Go' mileage on the trip computer seems to be messed up aswell. Its says 325 miles left when, after filling up, it only ever goes to about 225 miles. Its says my current average is 19.8mpg.
