1997 Maxima with P1445 and P0130, is it time to say goodbye?

I have a 1997 Nissan Maxima with 235,000 miles on it. Automatic transmission of which I believe there were two versions that year but I don't know which one is in my car. The car's been quite good but now it fails NJ inspection due to the following codes:

Th OBD reports P1445, P0130, and also reports P0325 but I don't believe the knock sensor (0325) issue will fail the vechicle in NJ.

The database here shows P1445 = Purge Volume Control
and P0130, O2 sensor or O2 Sensor circuit malfunction.

Any advice on what to swap to get this to pass inspection?

Thanks ... in advance,

Tony

The P1445 code refers to the Purge volume control valve circuit. The most common problem is a failure of the valve itself. It is located at the top of the intake plenum. Nissan offers an updated valve with a new bracket and hoses. If the updated bracket and hoses HAVE ALREADY been replaced in the past you will only need to replace the valve itself. The valve may be around the $150-$200 price range??

Keep in mind that the valve is the most common failure that I see, but there are also other causes. The system would have to be tested to find the exact cause. You need to decide how to handle the problem.

Code PO130 refers to a problem with the upstream O2 sensor for bank 1
(bank one is the firewall side of the engine). The O2 sensor itself is the most likely cause. The circuit should be tested to confirm the cause of the code. At 235K miles there could be many causes.

Good Luck!!

Also, according to a recent post, you're correct that a knock sensor code won't fail you(likely won't) because the knock sensor code doesn't illuminate the MIL. I'd be concerned about engine damage though, If the vehicle was driven without having it fixed. Pinging, etc. can damage your engine quickly.
