Daihastu Terios Fault code


Hey guy's , I'm new to this site and to Daihatsu.
I rescently purchased a 2000 Terios 1.3 and the engine warning light came on.
Had it checked on my machine and retrieved fault code
P0130 - Oxygen sensor 1 bank 1 circuit malfunction.
The oxygen sensor in the front pipe has been changed but light still comes on ( its fine for around 2 weeks after being cleared
and then comes on again.)
Is there any common problems with these or has anyboby else had this problem before Unknw
Any feed back would be much appreciated.

Thanks , Euskiluv
