I have a fault P0135 and P0155 possible causes

That hoses and check everything and apparently it is well any other possible cause thanks for the answers I will thoroughly verify the super thanks Mecaneitor

The ones that I mention are a thin that go through the tracera of the OBIO engine reach the multiple, they are like the windshield clean, its action is difficult but it can be, it would also be combined to check the temperature sensor kisas is extending your pulse.

For the codes it seems is the oxygen sensor as "fried" says. Have you changed it or tried? Luck

Good morning, I don't know if it's too late but oh, my contribution is going, according to the codes, the problem lies in the heater lines of the oxygen sensor, you do not say what car is, but if they are 4 cable cable quickly so that it has its normal operating temperature in this CADO The DTC are number 1 sensors that is before catalyst, luck

Look and go through the same thing and place the power sensor that is located in the Admission Camarin you have four cables and it is flat is subject with a screw when I get it shed it if with the circuit cleaner if it after mounted continues the fault looking for the four cable there is a cable that is positive another that gives positive then but when I turn on the car they would go out they would miss two that have to be black or negative of those two cable You will place the tester in positive and the tip place them in which you want from both of you will give you fail in another not in the one that does not fail you, you leave them and accelerate and verify that everything marks well xq that pass that code will give it to you the power sensor or HO2S11 indicates to Ecu Escape first and you will see that your problems is solved I did all these test and the final wing was the power sensor or H2S11 that are the same placed the current tester and improvement but in the scan it will come out that the turbo charger is high that wants to say that that information does not reach the ECU I hope this explanation serves you
