Replacing the oxygen O2 sensors may sometimes fix the code, but in most cases the catalytic convert needs to be replaced to fix the problem. She always starts right up and has absolutely no trouble getting through snow or mud. There are a very few transmission complaints, but nothing like the huge defect that shows up starting in with the 2005 model year. P0430 Nissan Description The Engine Control Module monitors the switching frequency ratio of heated oxygen sensors 1 front O2 sensor and heated oxygen sensors 2 rear O2 sensor. Tech notes As the code description implies the P0430 code means that the vehicle's control module has detected that the three-way catalytic converter is not working properly is not as efficient as the factory is expecting. Agreed: Not difficult to replace O-rings or the line. I use this vehicle for moving stuff and camping.
Feels sturdier than the earlier model. Use the right combination of socket extensions and universal joints to reach it by feel. I had zero issues for the first 120k and most of that was hard miles off-roading. For the average driver, this vehicle is pretty reliable with normal maintenance. It was operating fine then and still operates just fine so I'm not worried. A three way catalyst converter Manifold with high oxygen storage capacity will indicate a low switching frequency of heated oxygen sensor 2.
This vehicle is stable, reliable and drinks gasoline like a man who found an oasis in the middle of the dessert. Someone else wrote up this most of this list but I've experienced the exact same issues. No issues with passenger side motor mount. I have had to do some work to the car but not a whole lot. Great for hauling kayaks and climbing mountains.
The only thing prospective owners should be aware of are the less-than-perfect but acceptable crash test ratings. Replacing requires everything on top to be removed. When the frequency ratio of heated oxygen sensors 1 and 2 approaches a specified limit value, the three way catalyst malfunction is diagnosed. I do wish the interior was a little sturdier. . Only major changes I have had to do after buying the car used was changing oil and timing belt which is necessary after a certain number of miles. I did replace it last year but the light still came back on.
I opted to replace the head gasket because the intake was already going to be dismantled for the knock sensor valve replacement and she was leaking a little oil.

I didn't have any issues with it but a dealer replaced it anyways. The fabric is falling off of the ceiling. Upgrade to greasable tie rod ends and a hefty center link to prolong life. Read our to see people who found humor in a bad situation. Replaced with basic tools, along with plugs and wires.
As oxygen storage capacity decreases, the heated oxygen sensor 2 switching frequency will increase. Super easy and cheap to replace. If the P0430 code is combined with other codes, try fixing the other codes first. Find out more about our. I drove the 4x4 one and it was a fun ride, very roomy seats and comfortable for long drive.
