I got code PO420 and PO430

I have a Nissan sentra 2000 GXE. My engine light is on. I got Auto Zone to check it for me. They gave me the code PO420 and PO430 and did zero the light but it came back on again. Would you please let me know how can I fix it. Thanks. Niloo.

    I got the same codes in my car too. The car just clocked 72K miles. I bought it from a used car dealer and it came up just after 2 days. When I showed this to him, he told me nothing to worry. It will run for another 70K without any problem. Also he gave warranty on engine and transmission and he told me that this is out of warranty which he gave. Should I trust him or should I go ahead and show to the Nissan dealer? I found in web that even nissan dealers charge too much for fixing it. What should I do?

Here are the most common problems,

Air leaks at the exhaust manifold or in the exhaust pipes. Catalytic converter is damaged, contaminated or has failed. Front HO2S or rear HO2S is contaminated with fuel or moisture. Front HO2S and/or the rear HO2S is loose in the mounting hole. Front HO2S older (aged) than the rear HO2S (HO2S is lazy)

Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with one of the components or sensors it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and you need to diagnosed and repaired it. Autozone turning the light off does nothing for you, and is against their company policy. If you do not have the proper tool, reference materials or experience I would take it to a professional. Finding out the trouble code is just he start of the diagnosis process.

Hope this helps.

I just bought ford fiesta at the auction it got no power


Most likely it is the manifold converter. If 4 cylinder, you have 1, if 6 cylinder you have 2 manifold cat. converters and probably 1 under car. these do NOT go bad by them self. A misfire in the engine due to spark plugs (motorcraft only) ignition coil, etc....If check engine light on, take it to Auto Zone, etc... and they will scan it for free. Get scan codes.. Po420 and po430 are codes for bad converter. Good Luck

What could be causing my 02 Nissan Sentra to restrict revs then stall at highway speed?


Your first order of business is to check the oil level in the crankcase, and bring it up to full level. You can probably find a replacement dip stick, or go to a junkyard and get one. Without sufficient oil in the engine, The will seize. or prematurely die.
Is your check oil light coming on? Have the car scanned for trouble codes. Auto Zone and Advance Auto will a scan. Then you will be able to get info on the codes and what they identify. Just look the codes up on an internet search.

I'm getting trouble code p01320 on 2000 nissan


p1320 is a ignition primary signal code. you may need ignition coils. not a common issue on a 2000 sentra, but depending on milage you may need coils. unfortunatelly you dont have a specific cylinder number code stored such as p0301 which is number 1 cylinder misfire and so on in your case p0301 to p0304 because its a 4 cylinder vehicle. with the p1320 its usually the whole set of 4 coils.
