Asked by Daniel Dec 22, 2022 at 06:31 PM about the 2004 Dodge RAM 1500

Question type: Maintenance & Repair

I have a 2004 ram 1500 5.7 hemi v8. I am getting P0157 P0152 P0300 P0302
codes. The P0152 says that the o2 sensor bank 2 sensor 1 has a high
voltage.And P0157 says the o2 sensor bank 2 sensor 2 has  low voltage. The
P0300 is a general misfire code and The P0302 is a misfire in cylinder 2,
Does anyone know what could be causing the misfire?

Could be many things. Some are simple and some not. You will need to troubleshoot to determine more about the problem. I would start with the number 2 cylinder items like plugs, wires, injectors, coils. etc. Only knowing the failure code tells you where to start looking.
