So i have this code on my truck I reset it sometimes it takes 20 minutes to come back on other times a day or 2 to come back on. Does this mean I need a new cat? If this is the bank 2 cat then it looks to me like this cat has already been replaced/ Truck has about 65K miles on it. Thanks

 

Check the exhaust manifold bolts on the passengers side for loose or broken bolts that could be leaking and allowing fresh air to get sucked inside the exh pipe and passed by the front O2. P0430 is the 2/1 O2 so thats the pass side front O2.

 

so its the o2 and not the cat?

 

Correct, the front O2

 

alright I'll have a look at the exhaust bolts to see if any are loose if not buy a new o2

 

bolts seem fine on exhaust dont hear any leaks either. I just dont see why the truck wouldnt be throwing a front o2 sensor code and instead a p0430? How much can you guys get o2 sensor in the states cause up here it costs me $110 per sensor from the dealer. If someone wouldnt mind I'd like to get new o2 sensors for the front and if they are cheap enough I wouldnt mind paypal someone money for sensors and shipping. Thanks

 

don't get them from a dealer go to your local Bumper to bumper or NAPA dealer and get one. Out west here they run about $70 for an NTK.

 

i called napa and they wanted $129 for an ngk

 

Autozone had them for about 25 last I checked. Look on thier site and see which you need and if you need me to ship one to you just LMK. We can do USPS to pass through customs

 

i'd like to do both front o2 sensors before the cats I've already replaced both o2's after the cats. I'm sure youd know better which exact ones I need. After looking at the site I believe it's bosch 15504 are these plug and play?
