Grand Cherokee 2007 Failure

Hello, good afternoon, I have a 2007 Grand Cherokee, the Yellow Light of Check Engine was lit months ago, in the service they do not find the failure since the codes that yield correspond to the oxygen sensors connected to the PCM module, already change the sensors and the module 2 times
in the US such . I do not get anyone who can repair the fault
the codes are the following
P0155
P0185
P0161
P0135
P0301
If you can help me I thank you for
greetings
