I'm looking to buy a car and the owner says it has a couple codes or problems with it. It's got the P0500, P0600 and P1447 code. I need help on what things to look for, if I should buy any parts, if I can do any adjustments, anything. I'm not too knowledgeable about cars so I wouldn't know what to look for.
Code p 0500 is the VSS ( vehicle speed sensor)
code p 0600 is the CAN bus--malfunction
code p 1447 is the EVAP system
the car is 21 years old and there will be more problems that what you have been told about
The price that you would expect to pay is junk yard value and anything else would be a bottomless money pit for you

if our coil is sparking and good plug ive seen manny time carbon loose and sticking on the valve valve stay open doesnt build up compression = missing check our coil if its firing go on the road rev the engine like leave it in 2nd gear drive like that overreving the engine might loosen the carbon dont rev it to mush it cost nothing to try that and it work for me a few time pierre
SOURCE: code P1400 on a 1997 nissan maxima. help car wont pass inspection
P1400 on your vehicle is described as :Differential Pressure Feedback EGR Circuit Low Input You either need a new DPFE valve, or a new EGR valve. Both can be tested for functionality before replacing them both. EGR valve is more likely I think. Cleaning it may not improve its performance, but its worth a try. Also check the vacuum lines between the DPFE and EGR system. The EGR valve and DPFE are usually close together above the exhaust manifold/downpipe. you need service instructions to test these items, suggest you go to a garage really...

Speed sensor malfunction (Speed Sensor A)
Remove and replace.

Firstly, the code p1445 is actually an EVAP Canister Purge Control Valve...The most common problem is a failure of the valve itself, which is located at the top of the plenum chamber. Nissan offers a replacement valve with new bracket and hoses. It is around the $150-$200.00 mark.
But, remember to test the component (valve) first as this suggestion is just to the common problem, but in rare cases, it might be PCM related (water entry, shock etc)
Secondly, the p0500 code is a speed sensor and you can pick these up from autozone.....it provides the road speed for the speedometer and odometer..........if these are working fine, then you might have a wiring issue.
As these are 2 seperate systems, I doubt that they are related.
I hope this helps
