Codigos De Fallas OBD-2

  DTC Code  P0338  General Description The electric plug spark plugs are designed to heat up the combustion chamber, making it easier to start the engine at low temperatures. These plugs get hot before and during start-up.  Afterwards , they remain open to avoid engine failure until the ideal temperature for good performance is reached. This process reduces pollutant gas emissions and smoke levels when the engine is cold. The engine control module (ECM)  controls the heater plug by monitoring the coolant temperature and heater plug voltage. The heater system has eight separate power circuits between the controller and the heater plug. If the feedback voltage from the controller to the engine control module ( ECM ) is out of range,  DTC  code  P0338  is set. Fault code  P0338  General symptoms Check that the engine indicator light is illuminated. The engine is difficult to start, especially at low temperatures. Causes for OBD2 code  P0338  General Code P0338  may be caused by one or mor

  Description of DTC code  P0342  Generic The  CMP  ( camshaft position sensor ) is an electronic device used in engines to record the speed of the camshaft. This information is then sent to the ECM (Engine Control Module), which uses it to control fuel injection as well as ignition timing. The camshaft retraction is detected by the  CMP  sensor and thus identifies a particular cylinder. The piston position is also determined by the  CMP sensor . If there is a fault in this sensor, the ECM will not know when the valve is opening or closing. OBDII diagnostic code  P0342   refers to a low or insufficient CMP sensor signal. Fault code  P0342  Common symptoms Fault light is on. Difficulty starting the engine. Power loss. High fuel consumption. Cause of OBD2 code  P0342  Generic When DTC code  P0342  OBDII is established, it indicates one or more of the following faults. The camshaft position sensor (CMP) lead or connector may be damaged, resulting in a short circuit. The CMP sensor is faul
