Hello again,
Okay, they replaced the sensor, but have they checked the CMP wiring? The sensor could be brand new but if there is a problem with the electrical connector or the wires going to the PCM, you could have the best sensor in the world installed in your vehicle and it would make no difference. I have already sent you the engine management wiring diagrams previously, so in the diagrams down below I have included the guides for how to find intermittent problems in an electrical circuit, and how to find unwanted resistance in an automotive electrical circuit by the voltage drop method, the preferred way to do this. You will need to use a Digital Altimeter [DMM] to do this, so here is a link explaining how to do that, if needed, below:

Please go through these guides and test the CMP circuit, paying attention to the electrical connector and get back to us with what you are able to find out.
Thanks,
Alex
