Renault Repair Questions? Ask a Mechanic for Answers ASAP
Dear customer, I understand the problem you are presenting but I would like to know if you have any type of failures, because I am observing the error codes and in reality they can simply be wrong signals, the pressure sensor of the inlet manifold with the air temperature sensor and the egr control, they are referring to error code in air intake system basically there may be problems with the MAF sensor, or in the throttle body, it could also be having problems with vacuum leaks in the intake but all according to the symptoms that you present because if you are not experiencing any type of failure basically the problem can simply be a problem in one of the sensors or in the wiring as indicated by the previous owner.
Basically all subtraction codes referring to the air intake system therefore you could be calm, while no apparent failures are present, as for the indicator of checking the injection normally when we buy a second hand vehicle the previous owners do not worry about performing last maintenance to the injection system as a replacement for fuel filters, cleaning of injectors, verification of the pump that is why it is good that when you buy a used vehicle the first thing you do is to submit the vehicle a deep maintenance, this maintenance must also include the system air emission such as the throttle body, the EGR valve may also need maintenance and the problem will be corrected, if you get to have some type of failures such as a loss of power that the vehicle suddenly shuts off
