These include everything from controlling when your transmission shifts gears, to fuel injection parameters, to determining when to activate your check engine light. Needless to say, if your car\u2019s central computer is not functioning properly, your vehicle is not going to be running properly.<\/p>\n<p>How do you know your engine computer needs to be replaced?<\/p>\n<h2 class=\"sec-sub-title-2\">Signs Your ECM or PCM Might Need Replacing<\/h2>\n<ul>\n<li class=\"showbullet\">Check Engine Light\u00a0\u2013\u00a0The light goes on and off and doesn\u2019t seem to correspond to an actual mechanical problem.<\/li>\n<li class=\"showbullet\">Engine Stalling or Misfiring\u00a0\u2013\u00a0Stalling and misfiring may occur without any pattern to frequency or severity.<\/li>\n<li class=\"showbullet\">Engine Performance Issues\u00a0\u2013\u00a0You\u2019ll notice a reduction in fuel efficiency, power, and acceleration.<\/li>\n<li class=\"showbullet\">Car Not Starting\u00a0\u2013 Your vehicle does not start or is difficult to start. The engine may still crank but won\u2019t be able to start without vital inputs from the computer.<\/li>\n<\/ul>\n<p>It\u2019s important to not immediately jump to the conclusion that you have a bad PCM, ECM, or TCM if you encounter one of these signs. There are a number of mechanical issues that could also be producing the above symptoms. But if the cause of these issues does not seem to be a mechanical problem with your engine, then they are most likely the result of a faulty computer module.<\/p>\n<p>In addition to the performance issues listed above, if you (or a technician) run diagnostics on your vehicle and you receive any of the following error codes, you likely have a problem with your PCM:<\/p>\n<p><strong>P0600<\/strong> \u2013 Serial Communication Link<br \/>\n<strong>P0601<\/strong> \u2013 Internal Control Module Memory Check Sum Error<br \/>\n<strong>P0602<\/strong> \u2013 Control Module Programming Error<br \/>\n<strong>P0603<\/strong> \u2013 Internal Control Module Keep Alive Memory (KAM) Error<br \/>\n<strong>P0604<\/strong> \u2013 Internal Control Module Random Access Memory (RAM) Error<br \/>\n<strong>P0605<\/strong> \u2013 Internal Control Module Read Only Memory (ROM) Error<br \/>\n<strong>P0606<\/strong> \u2013 ECM\/PCM Processor<br \/>\n<strong>P0607<\/strong> \u2013 Control Module Performance<br \/>\n<strong>P0608<\/strong> \u2013 Control Module VSS Output \u2018A\u2019<br \/>\n<strong>P0609<\/strong> \u2013 Control Module VSS Output \u2018B\u2019<br \/>\n<strong>P0610<\/strong> \u2013 Control Module Vehicle Options Error<\/p>\n<h2 class=\"sec-sub-title-2\">When Do I Need to Replace My Car&#8217;s Computer?<\/h2>\n<p>If you experience any of the issues above and you have a mechanic or technician run additional tests and diagnostics to confirm that the issues are caused by a faulty PCM (or TCM or ECM), you are going to want to correct the problem as soon as possible.<\/p>\n<p>Because your car\u2019s computer module affects so many processes within your engine, a faulty unit can lead to much worse problems and more costly repairs down the road, inefficient engine performance, or even complete engine failure. This is definitely not something you want to put off repairing.<\/p>\n<p>Due to their price, nearly all aftermarket replacement PCMs are &#8220;remanufactured&#8221; units. Typically, PCMs are not rebuilt in the same way that alternators and water pumps because there are no mechanical parts that wear out. Remanufacturing a PCM generally means testing the computer, isolating and repairing any faults that may be found, then retesting the computer to make sure everything works correctly.<\/p>\n<h2 class=\"sec-sub-title-2\">PCM Replacement<\/h2>\n<p>But the good thing is, if it\u2019s time to replace your PCM we have you covered at Car Computer Exchange. There\u2019s no need to take it into the dealership or to the mechanic\u2019s shop and pay a bunch of money for a technician to install a new engine control module.<\/p>\n<p>All you have to do is visit our website, enter in some basic information, and then follow a few simple steps to get your car up and running like new again. If you can change your oil, you can replace your car\u2019s PCM, ECM, or TCM. Replacing it is essentially a matter of swapping boxes\u2014the tricky part is making sure they are programmed correctly for your vehicle. And we have you covered on that end.<\/p>\n<p>At Car Computer Exchange, we carry PCMs, ECMs, and TCMs for a variety of car brands including Chrysler, Dodge, Jeep, Mercedes, Plymouth, Ford, Lincoln, Mercury, Lexus, and Toyota. And we have a depth of inventory, even for older model vehicles. For example, we carry a complete selection of Chrysler PCMs for nearly any model manufactured in the last 20 years.<\/p>\n<p>What\u2019s more, each PCM or ECM we sell is programmed with all the latest manufacturer software and tailored specifically to the make, model, and year of your specific vehicle. And in addition to that, each time you purchase a reprogrammed PCM, ECM, or TCM from Car Computer Exchange, you get:<\/p>\n<ul>\n<li class=\"showbullet\">100% Plug-and-Play.\u00a0No need to visit the dealer!<\/li>\n<li class=\"showbullet\">Each module is\u00a0pre-programmed\u00a0to your cars VIN and\u00a0compatible\u00a0with all motor sizes, transmissions, and emission types.<\/li>\n<li class=\"showbullet\">100% Iron-Clad\u00a0Guarantee<\/li>\n<li class=\"showbullet\">FREE\u00a0Lifetime\u00a0Warranty<\/li>\n<\/ul>\n<p>When it\u2019s time to replace your PCM, ECM, or TCM it\u2019s to your benefit to get it done as soon as possible. If you put it off you will likely face bigger problems down the road. The good news is, we make it easy and economical for you to get a PCM programmed specifically for your vehicle, and which will have it running like new.<\/p>\n<p>All you have to do is enter in the make, model, and year of your car and check the different computer modules we offer today.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A malfunctioning or failing powertrain control module
