Mercedes P0130 P0150

Hello
first of all, it helps ... I am with a problem of these two codes P0130 and P0150 with a Mercedes E320 Year 96 Elegance
already change the sensors 02 Review exhaust leaks, air tickets ... Picos ... I appreciate any suggestion

According to the manual, these codes are of sensors 1 of the 2 engine bankos and are fixed because the sensors remain generating 0.4 to 0.6V for more than 15 seconds so that you fail you of the 2 is that the engine fails, it can be very poor of fuel. What you can do is see the live data with a scanner The sensors generate up to 0.9 or at one end 1.2V if the fuel mixture is too rich and only go up when it brushesly accelerates. Minimal launched almost always vary constantly and if the sensors do not vary much or remain static they give this type of problem. Tellos how these sensors vary even to help you or if your vehicle has air flow sensor testing it or changing it for another forever watching the reaction of oxygen sensors


Here is a capture of the repair procedure of these codes
