But here are the meanings of your codes
13. Oxygen sensor signal stays lean during warm engine cruise
23. Low temperature at manifold air temperature sensor OR
Throttle position sensor error
44. Oxygen sensor lean
54. Low voltage at fuel pump OR
Low voltage at Fuel pump relay OR
Output failure at quad driver module

Clear codes, read, if code resets then:
13 - Oxygen Sensor voltage fixed at 0.35 -0.55vdc; open circuit condition.
23 - MAT reading below -22°F with KOEO
44 - Oxygen Sensor voltage below 0.35vdc (engine idle @ 1000rpm/coolant (167°F to 203°) lean exhaust, or signal short circuit to ground.
54 - low fuel pump voltage.
