P0103 Error Description Mass Air Flow (MAF) Circuit High Input The MAF sensor circuit is monitored by the PCM for high air flow (or voltage) input through the comprehensive component monitor (CCM). If during key ON engine OFF or key ON engine running the air flow (or voltage) changes above a maximum calibrated limit, the test fails. Possible Faults MAF sensor screen is blocked MAF circuit shorted to VPWR Damaged MAF sensor Damaged PCM A MAF V PID (MAF PID) reading less than 4.6 volts (Refer to equivalent grams/second chart in GO to Pinpoint Test DC ) in continuous memory or key ON and engine running indicates a hard fault. P0106 Error Description Barometric Pressure Sensor Circuit in within limits Barometric (BARO) Pressure Sensor Circuit Performance Baro sensor input to the PCM is monitored and is not within the calibrated value.

will find the most complete list of Ford trouble codes available. The code definitions are a good starting point when determining the cause of the service engine light but where do you go from there? We have a large number of resources https://www.engine-light-help.com/ford-check-engine-light.html to help you repair the problem. Here is how we suggest you proceed. Look up your code definition. This tells you where to start testing. If you are unsure of any abbreviations, check out the acronym list by clicking http://fordfiestast.co.uk/ubbthreads.php/topics/49975/Re:_Fault_codes??? on the link at the left. Next, read our article Automotive Circuit Testing 101, and if there is an article related to the system you are testing, such as Oxygen Sensors or EGR concerns, read these as well. They ford fiesta will provide valuable info! If there is a link to a specific diagnosis strategy for the code then follow that and start testing. If there is no procedure for your manufacturer specific code, then I suggest referring to a similar generic OBD II code (these are listed numerically by system type) to get a good idea of what to look for. If at this point you still need assistance use the "Get Help" link and let us know ford fiesta fault how we can help. We can provide information on component location, specifications, circuit color/location and more. We do ask that you please read the info available on the site first so that we can help reduce repeat questions. So please read our Disclaimer and when you're ready jump in! Also, we value your feedback and like to hear stories of unusual fixes or concerns you may have run into with your Check Engine Light, so feel free to share your experiences by using the "Contact Us" link. Let's go! We do our best to update these Ford check engine light codes as frequently as possible. If you find one missing let us know and we we'll add it immediately! Please use the form on our Contact Page to get in touch with us. We certainly understand how frustrating it can be to look for a code definition and have it not online when you need it. And lets face it, if the service engine light is on then you need it now! It's easiest to use the "Find On This Page" feature of your browser's "Edit" menu to find codes on this page as the list is quite long. These are listed in numerical order for easy searching. When retrieving Ford check engine light codes with an OBD II scan tool, proceed as follows: 1. Connect scan tool to the 16-pin da

MichaelST1 Fiesta Crazy Registered: 07/07/05 Posts: 559 I remember a while back someone posted a list of all fault codes... would anyone know what post it was in??Cheers Top #49971 - 12/07/06 06:16 PM Re: Fault codes??? [Re: MichaelST1] ChrisCumbria Driving as Daily Registered: 26/06/05 Posts: 22339 Loc: Whitehaven, Cumbria I can't seem to find a post with that either. Theres a post in this thread here in which Richt mentions that he'd pm'd the fault codes to someone:http://www.fordfiestast.co.uk/showflat.php?Cat=0&Number=42613&page=0&fpart=2&vc=1So might be worth contacting him. _________________________ Top #49972 - 12/07/06 10:07 PM Re: Fault codes??? [Re: ChrisCumbria] DAVE T ST Fiesta Nutter Registered: 15/01/06 Posts: 3556 Loc: Tipton nr. Dudley, W. Mids DTC Codes Here is a bit of info for the test mode of the focus/fiesta dash.. Long but informative To access the test mode, hold the trip meter reset button in and turn the key to the on position, then the gauges will do a full sweep and state gauge on the LCD.. You are then able to press the button to get the details /--------------------------------------------------------\ First digit structure is as follows: Pxxxx for power train Bxxxx for body Cxxxx for chassis Uxxxx for future systems Second digit structure is: P0xxx Government required codes P1xxx Manufacturer codes for additional emission system function; not required but reported to the government Third digit structure is: Px1xx measurement of air and fuel Px2xx measurement of air and fuel Px3xx ignition system Px4xx additional emission control Px5xx speed and idle regulation Px6xx computer and output signals Px7xx transmission Px8xx transmission Px9xx control modules, input and output signals The fourth and fifth digits designate the individual components and systems. Here's a generic list of DTC codes for reference, makes the post a bit long but should do. These are for SAE standard ones, as used for SAE J2012 OBD-II: Anatomy of the Diagnostic Trouble Code A DTC is made up of 5 digits. The figure below demonstrates the composit
