Motor failure

I have a problem with a Peugeot Year 2001 Model 306 Motor NFT 1.6CC, when lighting it the light of Check Engine and begins the march and the light never goes out, but the engine does not feel any problem, it has good power, good march, the consumption of gasoline is normal, what problem will it be?

In the agency they told me that the vehicle was very old and it could be the idle sensor and that there is no resumption

, what can I do? Thank you.

Hello, the check is turned on by any sensor or actuator that is not generating a signal that does not correspond in some cases the air temperature sensor is a cause and no failures in the operation are not noticed in another case to ask the one who installs the Scaner the fault number recorded so I can help you what is the problem.

Hello friend, spare parts are achieved so I think they want to see you, the fellow Maurog is right, ask for the fault data and we can guide you, greetings.

The fault code or the designation of the same is true and the designation of it, you have to take into account that there are spare parts for that type of vehicle, Peugeot in a begins put their own codes other than the OBD 2, these codes appear as Peugeot code and they mean nothing just put them to realize maintenance and repairs that do not exist that they do not have to take money to the customers. The code is important they have to give you when you entertain the scanner.

Thank you companions who responded to my concern of the motor failure, I will try to get the Averia code by other means other than the agency.

If possible, they could provide me with an injection system diagram of this vehicle, because I do not identify the engine temperature sensor in the engine
