new car 2 weeks check engine light comes on?

[morbidsanity]

so i bought a 2000 4runner sr5 2 weeks ago,today the check engin light came on,i took it in and got the codes here they are

P1130 Air-Fuel Sensor Circuit Range/Performance.

P1135 Air-Fuel Sensor Heater Circuit Response.

is this a problem? will i damage my car if i continue to drive? what can i do?

looks like you need a new a/f sensor, not a huge problem but may kill your mpg's a bit. yes it's ok to drive until replaced, maybe try clearing the code first to see if it comes back than replace. and replace with a denso sensor only.

and how do i clear the code?

the sensor is located on the exhaust pipe just before the cat converter, you can clear the code by pulling the efi relay in the under hood fuse box for 30 mins or so.

here's a good writeup to get you started:

Pull the negative battery lead for like a minute. That will reset the code, clock wont have any issues, but the radio presets will be goine.
