I've had a lot of issues with the emission system on this vehicle.
First the fuel level indicator had to be replaced, then I had the service engine light come on for P0430 Catalyst efficiency below threshold (bank 2), but then after a week or two, the service engine light suddenly turned off. Then it came back on three weeks later with the same error code, but with an additional error code for the EVAP canister.
So, I brought it to the garage and they replaced the canister and checked the P0430 with a 3-way test on the catalytic converters. It turned out the converters were fine and they erased the codes. I paid for the service and drove my vehicle back home, but three days later the P0430 error code came back on.
I took it to a different Nissan garage and they said I need two new converters. Oh yeah, they also gave me a bill of 800 dollars before they even touched the problem I brought in there for.
So anyways, I've only had two trucks before this, but I have never had this many issues with a truck. I am still trying to figure out the P0430 code, and it's been two months.
I just did a vacuum and pressure tests on the catalytic converters, and the results showed that they were fine.
