Hello everyone,

I want to clean my four O2 sensors because of my p0300 error, but I don't know if it still works or buy a New one?

Hello everyone,

I want to clean my four O2 sensors because of my p0300 error, but I don't know where exactly they are, and can i unscrew it and clean it without disconnecting the connector on the other side?

only find something online about 4.2

Need a description.

Thanks a lot guys!!
I highly recommend that you spray them with PB Blaster and let them soak over night. The O2 sensors can be a pain to remove; especially if they are the factory originals.

And spend a few bucks on an o2 removal tool wearher socket or wrench, the amount of heat cycles they see a regular wrench will round off the soft steel head real quick.
