Are you sure that you have the correct code number? What year, make, model?

Diagnostic Trouble Codes P1100 and above are manufacturer specific, meaning that a code number may have a completely different definition between a Kia and a Ford, for example. My info says that Ford DTC P1295 is for an injector fault on Bank 1 (passenger side) FOR DIESEL ONLY.

Bank 1, sensor 1 is the oxygen sensor closest to the engine on the passenger side.

The troubleshooting guide has a long laundry list of possibles but many are not common. I'd look for anything simple that could cause a lean condition at the sensor with emphasis on the passenger side:
  • port vacuum leak
  • dirty injector(s)
  • exhaust leak upstream of Oxygen Sensor 1-1
  • defective or contaminated Oxygen Sensor 1-1
There are a few other possibilities but these will often (not always) trigger codes for sensors in both banks:
  • manifold vacuum leak
  • unmetered air leak
  • PCV leak
  • evap system leak
  • dirty MAF element
  • low fuel pressure
