Honda accord y2000 vtec 2000ccm Europe model
engine: F20B6

I'm getting these errors(paperclip+jump the blue connector) :
(I'm not sure about the descriptions)

22 (2 long 2 short)
VTEC Oil Pressure Switch?

41 (4 long 1 short)
Primary Oxygen Sensor - Heater?
circuit malfunction?

48 (4 long 8 short)
LAF Sensor (Lean Air Fuel)?
defective circuit or unplugged / defective sensor?


Car runs and drives normally, I wonder what these errors mean, if it's
safe to drive the car?

Please if anyone can give me info about repair cost and if I can
repair it by myself (is it too complicated)?
