2005 chevy astro code po59 - 2004 Chevrolet Astro

Answers :

No such code listed, there is a P0059, which is a HO2S Bank 2 Sensor 1 Heater Resistance, Meaning your #2 O2 Sensor is starting to fail, go to Auto Zone and they will get you a price , a part, and give you the location for replacing it.
HI, the DTC your Astro has set POO59 is set when the computer doesn't see the oxygen sensor heating up fast enough. This DTC is for the bank 2 sensor 1 oxygen sensor. I have rarely come across and other failure for this code other then the O2 its self. I would recommend to my customer to replace this sensor. Good luck and happy motoring
