VW BORA YEAR 2003

Gentlemen of the Forum I have problems with a VW Bora year 2003, M throws two codes very often, one is the P0420. Catalyzer system, block 1 low threshold efficiency, the catalyst is already changed, and the sensor measures well, and the medium, and the other is that of P0116, engine temperature sensor, rank problems, or operating, and the vehicle works impeque, but throws me those failures, the tempera does not rise more than normal, the thermostat opens at its normal temperature, I erase the failures and the next day. I thank you for your cooperation.

I would like to know if the code of your engine is bej, it is important to know, because I have a 2003 bej, which presented the same problem, but changed the temperature sensor and that problem was solved, you must check the real data of the sensor, look if the temperature varies something fast, if so, your sensor should change it, it is very economical, if you changed your catalyst, you put an obd II or one Generic ?????? Because the VWs must carry the correct catalyst, but will not turn off the focus of the check.

I would have to check the motor code, but the temperature sensor has already been changed, an original one was placed, and the values ​​that it delivers in the scanner, compared to a gun that measures temperature is inside the range, the catalyst seems to me that it is generic, thanks for the contribution
