AZ does it again.
P0152 is the DTC for upstream, bank two, oxygen sensor. That is telling you that there is a problem in that system, not that the part is bad. The condition to set P0152 is, generally, due to overfueling. Check TPS and fuel pressure, then report back with findings. The Vortec injection system is known for leaky pressure regulators and fuel feed lines.
