Good evening, the most likely causes for this code are damaged wiring going to the o2 sensor. The other possible cause is the powertrain controller. This last possible cause is the least likely. Inorder to accurately check the code further if no obvious wiring problems is to you a scanner that can read the o2 sensor voltage.
Here is the actual trouble shooting steps for the code:
If this answers your question then press ACCEPT. If you need more help then let me know. Thanks
I just installed a True flow cold air intake system and right after that is when the light came on, the 02 sensor goes into that tube ,I think that it maybe it's not in the right position. what do you think?
