I have ford f 4. Had a new fuel pump the whole assembly … original equipment not aftermarket installed about 3 months ago mid-June and changed the fuel filter as well. Mostly I drive it only once per week … just long enough to get everything warmed up at least 20 minutes or so. So, since the fuel pump change I have only put about miles on it. Given that it idles and seems to run smoothly, would you say the O2 sensor is the likely culprit? Or should I investigate other possibilities first? Have you cleared the code once? If not get it cleared and see what happens. If you can get to Alldata, the DTC section has the list. The main catagories are electrical system, fuel system, EGR system, induction system, and base engine. What you would be looking for is something that is allowing too much oxygen into the exhaust gases. It could be a vacuum leak, a bad dip stick seal, a leaking exhaust gasket, cracked exhaust manifold, etc. With K miles, a check of the integrity of the exhaust system would be in order.

While this may seem harmless at first, keep it hanging for long enough, leading to part damages and decreased fuel economy. The P Ford code is linked to the oxygen sensor and signals the engine is running on a lean or rich fuel mixture. This article will discuss everything about the P Ford code, from what it means to diagnosis and fixes. Error Code P is displayed when sensor 1 or the oxygen sensor bank 1 does not switch enough to lean. The heated oxygen sensor voltage is below 0. Any Error Code that begins with P1xxx is a manufacturer-specific diagnostic trouble code.

Best you can do is go with air leak first and test the other possibilities and look at live data to see when you got the repair. Now what? Otherwise you would most likley have and DTC's accompanying. P is the only code. The time now is AM. The is telling you the system is trying to correct for a perceived over rich condition. Leaking injector. I have ford f 4. What does he want? All times are GMT Or should I investigate other possibilities first? I explained three times, as help, to get him started.

Bluegrass was just giving some pointers as to what could be the cause.
