Check Engine Light came on and stayed on because that a pair of days.I take it the SUV come the dealer because that it to it is in checked.The dealer tells me the P0430 password comes up and also that the financial institution 2 Catalytic Converter requirements to be replaced.Question 1) Does financial institution 2 refer to the prior Cat Converters or the rear?The driver"s side or passenger side? ( there space 2 fore & 2 rear)Question 2) I have actually read in the forum whereby some civilization have to be able to fix the trouble by replacing the O2 sensor only. What test deserve to be excellent to further determine if that is the sensor and not the converter?
1. Financial institution 2 way it"s the driver side. (Image here: 1996-2011 Nissan Pathfinder A/F Sensor - O2 Sensor location | usmam.org.com). The catalytic converter that falls short is the prior one.2. The only test I know is through an oscilloscope. You can examine the graph that the O2 sensor. Trouble is that if the cat is not working properly, the signal indigenous the sensor it"s not an extremely accurate. It"s feasible that replacing the sensors might take treatment of the problem, however it"s no common.

Usually once the ousmam.orgygen sensor fails, that will collection a problem code. Catalyst performance codes deserve to be a tiny "flakey." You can erase them and all will be fine because that a few weeks and also then they"re back. Ns think a most those human being who speak they changed the sensor and also fiusmam.orged the trouble actually didn"t fiusmam.org noþeles so much as the code merely hasn"t come back...yet. Because that this reason, ns suggest civilization erase the code and see if that re-triggers before spending a many money to change the catalytic converter. If the catalyst performance code return without any type of other code(s), it"s likely the converter is poor (assuming there space no eusmam.orghaust leaks). The upstream converters space the just ones that are monitored for effectiveness by the ECM. In a way, they additionally sort the act choose a filter for the rear converters, so it"s rare to check out the rear cat fail.
