Trouble In AC Acedes-Magna C2514 Possible Cause

Common cause for AC Acedes-Magna C2514 is the valve is controlled by the PCM (or a similar controller) using inputs from sensors and other controllers in the controller area network (CAN). The CAN represents a communication bus that allows multiple microcontrollers.

Common Symptoms For AC Acedes-Magna C2514

  1. CAN is the abbreviation for "controller area network." The CAN represents a communication bus that allows multiple microcontrollers to communicate with one another without the need for a host computer
  2. If the resistance level does not decrease with heat and increase as it cools, replace the sensor. If everything has checked out thus far, turn the key to the "ON" position and test for the presence of a voltage (and a ground signal) at the exhaust gas temperature/pressure (or heated oxygen) sensor electrical connector
  3. Many vehicle applications utilize an electronically controlled valve in the automatic transmission cooler lines to regulate the flow of fluid to the cooler itself
  4. If the fuel shutoff switch and all system circuitry checks out, suspect a defective PCM (or other related controller)

AC Acedes-Magna C2514 Troubleshooting

Having one of the signs of a bad gasket is usually not enough to prove a failure of a gasket, but multiple symptoms are most likely the result of gasket failure. It is advisable to have the vehicle driven as little as possible whenever the symptoms occur. Depending on the symptoms, either have the gasket replaced or repaired.
The cost of replacing a gasket usually varies from one mechanic to the other. Replacing a gasket is quite expensive in modern engines due to their location and the amount of labor that is required to replace them. AC Acedes-Magna C2514 OBD2 reports a sensor fault, replacement of the sensor is unlikely to resolve the underlying problem. 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.
