trying to decide if i want to do it myself. not a ? of if I can do it. rather its a matter of time [busy season at work] thax for any help

 

do u know u may not even need to replace that on most maxima the code is p0430 and if u have less than 80,000 miles they reprogram ur ecu for free and it would stop pulling that code i think we are talking about the same thing

 

89 k and my ecu dose not need the upgrade [i wish it did]
