RNS-11Z

Hi guys

i had a couple of fault codes pop up:

P0133 - 02 sensor circuit slow response bank 1 sensor 1
P2237 - 02 sensor positive current circuit/ open bank 1 sensor 1

What does this mean? Is it the 02 sensor on the exhaust?
I cleared the codes, the car drives fine aswel. Is it safe to drive or should i get it fixed asap?

thanks

Seems to be just as you have said. Better get it fixed soon.

Thanks for that.
I need to drive the car over the weekend. Would it be safe to do so?

I am not too sure but I will get it fix ASAP. If the O2 sensors are going bad, then it will affact your fuel mixture for the engine.

Oxygen Sensor Failures Can Mean
Big $$ In Repairs If Not Replaced

The normal aging process will eventually cause the oxygen sensor to fail. However, the sensor may also fail prematurely if it becomes contaminated with lead from leaded gasoline, phosphorus from excessive oil consumption or silicone from internal coolant leaks or using silicone sprays or gasket sealers on the engine. Environmental factors such as road splash, salt, oil and dirt can also cause a sensor to fail, as can mechanical stress or mishandling.
A dead sensor will prevent the onboard computer from making the necessary air/fuel corrections, causing the air/fuel mixture to run rich in the "open loop" mode of operation, resulting in much higher fuel consumption and emissions.
An additional consequence of any oxygen sensor failure may be damage to the catalytic converter. A rich operating condition causes the converter to run hotter than normal. If the converter gets hot enough, the catalyst substrate inside may actually melt forming a partial or complete blockage. The result can be a drastic drop in highway performance or stalling because of a buildup of backpressure in the exhaust system.
