Hi everyone. I gained a serious headache on mine hands. 2001 Nissan maxima SE through approx 180,000 miles. It was marking p0430 catalytic converter bank 2 listed below threshold. I replaced it through a used WORKING converter native an infiniti i35. Whatever is similar same motor and also all. The Infiniti simply passed smog and also was totaled therefore they offered me the finish exhaust system which i switched out with the maxima. Ns erased the codes and it was saying two sensors (o2 and catalytic were not ready) then ultimately my inspect engine irradiate came earlier on. I replaced the o2 sensor on bank two i m sorry I think is right below the one on top by the radiator. Any type of ideas??? I have to pass smog within 2 weeks! Thanks!
Check spark and also fuel because that the cylinders the feed bank 2, also make sure that you actually changed the financial institution 2 downstream sensor (not the bank 1 or upstream sensor). Lastly, try replacing the upstream bank 2 sensor. Don"t skip any possible vacuum leaks.
Surprisingly, a gradually dying MAF sensor can cause P0420/0430 and an additional O2 codes. I recently replaced my initial MAF in my "02 through the to update AM600 MAF and my consistent P0430 and secondary O2 codes at an initial stopped coming back as quickly, now haven"t had any kind of in more than a week and also 500+ mile of driving.
Does this MAF work-related in the "01 together well? Is it easily accessible through the virtual aftermarket suppliers? If so, how can it be differentiated from the "original"?
The "00-01s usage the same MAF because that those 2 years only. Not very expensive, must be $100 or a tiny less also through the dealer. The "02-03 MAFs are recognized for failure, particularly the ones on Maximas v a construct date prior to 10/01, the AM600 MAF apparently is a lot an ext reliable. The key reason I got it is the I have a 6 rate "02 and also it has a hesitation once you accelerate and also I required the update MAF for the ECU reflash come cure the hesitation. The lack of codes is a happy side effect.
