Pouvez-vous publier en anglais car la plupart d'entre nous ne parlons pas français. Votre commentaire: "avoir déjà donné 5 éléments pour le même échec ne me donne pas la voiture en l'air" n'a aucun sens; reformulez-le.

Le véhicule est en mode preventative, et limite sa vitesse pour minimiser les domages au moteur. C'est un problème sérieux et il faudra faire lire les codes d'erreur du moteur ( ou de la transmission). Un CVT qui date de 2003 est fort problablement rendu a ses derniers jours.

You may have old spark plugs, consider replacing them; also replace the air filter while you're at it.

Hello sir I have change spark plugs and air filter but my consommation is the same . How ca I do
The O2 sensors or the MAF may not be operating correctly thus creating a richer mixture to be burned. The first thing you might want to do is perform an ECU code readout with a portable scan tool to see if any fault codes are set. The tool can be purchased at most auto parts stores or online at Amazon.com; also most auto parts stores can perform an ECU code readout free of charge. Post the actual codes here on the forum so that we may be able to help you further. If there is one or more fault codes set, they can help point to the malfunction. A fault code starts with the letter P followed by a 4 digit numeric.

The P0550 code indicates a problem with the power steering pressure (PSP) sensor in the high-pressure tube that detects a power steering load. This sensor is a potentiometer which transforms the power steering load into output voltage, and sends a signal to the ECU. The ECU controls the electric throttle control actuator and adjusts the throttle valve opening angle to increase the engine speed and adjusts the idle speed for the increased load.

The P1800 code indicates a problem with the VIAS system. VIAS stands for Variable Intake Air system. It is made up of a power rod going through your intake manifold that holds a series of butterfly valves. A solenoid turns the rod at 5000 rpm to open the valves to allow the engine to breathe better. This problem could excessive fuel usage.
