This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light is on diagnostic inspection.
The P trouble code marks a performance problem with the control module. The code suggests that the ECM is experiencing problems, such as power failure or memory loss, and thus may not be able to do its job properly. The vehicle may also have a problem starting, or may fail to start at all though the engine will likely crank.
If the vehicle does start, you may experience some engine issues, and the vehicle may even stall while you are driving. Fuel economy and smoothness of driving will likely be negatively impacted as well.
A qualified mechanic will look at the freeze frame data to try and determine any related issues or clues for the P code. The trouble codes will then be reset, and the car restarted, to see if the codes remain. If the P code does not resurface, the ECM may be in working order, though the mechanic should still check the electrical system to make sure everything is in working order.
If the P code returns following the trouble code reset, the technician will first check the electrical system. If the battery or the alternator are not providing proper electrical power to the ECM, the ECM will malfunction and the P code may be triggered. If the battery and alternator are in working order, the mechanic will check the ECM itself to see if there is water damage, corrosion, poor connections, or an improperly routed wire harness.
The most frequent mistake that is made when diagnosing the P code is not following the correct trouble code diagnostic protocol.
If a technician skips steps, they may misdiagnose the code. The P code can vary in severity. Sometimes the code coming on is a fluke, and there is no actual problem with the ECM or the vehicle. At its worst, however, the P code means that the ECM is malfunctioning or the battery is dying.
If your battery has recently been changed, the ECM may have lost power and need to be reprogrammed. YourMechanic offers certified mobile mechanics who will come to your home or office to diagnose and repair your vehicle.

The fault is most likely to be caused by the systems that the sensor is monitoring, but might even be caused by the wiring to the sensor itself. The leak detection pump is part of the evaporative emissions system. This system tests the fuel system to make sure it is not leaking fuel vapors into the air.
The system pulls a vacuum on the fuel system and holds it for a period of time. In-line Ford engines, along with those of most other manufacturers, begin the numbering of cylinders at the front and proceed in numerical order toward the back.
In the V-engine design, Ford follows a similar design with the number one cylinder at the front left of the engine. In the V-6 configuration, cylinder 4 is at the front right of the engine and in a V-8, cylinder number 5 is in that location.
Other manufacturers sometimes use an alternating pattern in the V-engines. When you turn on the ignition, the Service Engine Soon or Check Engine B Subaru light should flash briefly, indicating that the OBD system is ready to scan your vehicle for any malfunctions. After this brief flash, the light should stay off while you drive as long as no problems are detected.

Loss of Power — It is a really strange feeling to drive a vehicle with a catalytic converter that is going out. Oxygen Sensor — The P codes is thrown when the oxygen sensors on both sides of the exhaust have very similar readings. When the oxygen sensor is bad, it can cause a false reading and trigger the code. Over time, they can become clogged. Although, modern catalytic converters are supposed to last the life of most vehicles, it could be there is some underlying problem if it has clogged.

Supposed to be doing a 3,km road trip on Friday. Quietly shitting my pants. All input is appreciated. It would mostly occur when I would leaving my place which is on a hill, so it would stall under load and go into limp mode. Initially Matt disabled the code but it would still go into limp mode only difference is that the engine light does not pop up.
Matt had to change the DBW setting back to stock, apparently his settings were too aggressive and for some reason our model pre-fl didn't seem to like it. Hopefully this helps you rectify the problem because I know how frustrating it was. Cheers, Tony. Hate to say it, changing table scalars willy nilly with related referenced tables not being understood would trigger this behaviour.
Hope you can wear the cost of some of these experiments. Work is x; y is play; and z is keeping your mouth shut. I had the tune done probably 8 months ago, in that period it would throw a cel maybe every 4 weeks on average, but has been getting progressively worse over the past few days.
I have been informed the avcs filters can cause issues similar- and checking on obvious things like throttle body leaks. Will see how I go. The tune was done in person so I do not have a tactrix to reload the stock tune.
Thanks guys. Addicted to corn juice My FrankenStien build thread here: viewtopic. I have been in close contact with Matt - the problem seems to intermittent it's hard to pinpoint. I will definitely be getting the tune revised when I can get my hands on a tactrix.
