P0402 - DPFE sensor is bad and needs to be replaced, make sure you get the revised plastic one also
It's not that simple.
A P0401 could be a number of things, the most common would be the TB ports. It an also be the DPFE sensor.
A P0402 could also be a number of things of which the DPFE sensor is only one.
In each case, additional troubleshooting is recommended. Failure to do so will greatly increase the odds that you will waste either time or money.
