  On all modern autos there is a pc that controls the way the engine operates, this pc is known as Electronic Control Module, or ECM. The objective of the ECM is to maintain the engine running within emissions limits and at top effectiveness. Identify new information on our favorite partner encyclopedia by going to analyze dodge caravan ecm. I learned about ecm dodge caravan by browsing webpages. With the quite strict emission regulations of these days, this is not an simple process to obtain. Precise and continual adjustments to match several conditions of the engine must be made by the ECM in regards to speed, load, engine temperature and others.
  
  How the ECM performs:
  
  A quantity of sensors are accessible that offer the ECM with the information it requirements, such inputs are engine and ambient temperature, vehicle speed and load. The ECM makes adjustments by advancing or retarding the ignition timing, adds or subtracts fuel or increases and decreases the idle speed.
  
  In the exhaust, ahead of the catalytic converter, an oxygen sensor monitors the good quality of the combustion produced in the cylinders. This compelling jump button web site has diverse interesting suggestions for the reason for it. The sensor creates a feedback that is then utilized by the ECM to make fine adjustments to the fuel-air mixture with the objective to decrease emissions. Immediately after the catalytic converter, yet another sensor in the exhaust monitors it is effectiveness
  
  Other extra emission handle systems exist, such as the Evaporative Technique, or EVAP. The objective of EVAP is to avoid vapors of gasoline, from the gas tank, from getting released into the environment. There are also a number of sensors and actuators that are controlled by the ECM.
  
  The operation of sensors and other engine elements is consistently tested by the self-diagnostic capability of the ECM. If one of the signals is missing or if it is not in the typical range then the Examine Engine light is illuminated and the Diagnostic Difficulty Code, DTC, is stored in the memory of the ECM.

  With a specific scan tool, the stored code can be retrieved by a technician, that will then know only a course exactly where to look for. The code doesn't inform distinct information about the failure, specific tests have to be performed for every single code, in order to uncover the precise lead to of the dilemma.
