My check engine irradiate is on, had actually it experiment twice and also am being told by one location that it might be dirty gas, bad vacuum leak, or catalytic converter, cure the gas, cleared the code, drove about 40 or 50 miles and also check engine irradiate came back on. Mine mechanic states it is shooting a code for catalytic converter. How countless catalytic converters go this car have and also how do I recognize which one is bad? Thanks!

JACOBANDNICKOLAS There space three. One attaches to the front financial institution of cylinders close to the radiator, another attaches come the rear financial institution of cylinders near the firewall. Those both feed into a Y pipe that goes under the floor and has the third converter in it. The prior two room the most often replaced. Who ever before told you the doesn't know. Correctly it tote three.
Is the true that ns can get a complimentary catalytic converter if mine is messed increase as lengthy as it much less than ten yrs old? I have an 05 nissan maxima.
usually emissionitems space warrantied for 80,000 miles however I don"t understand the timeline years wise. All you must do is contact a dealer and ask they will certainly know.
ns was freshly told through a nissan dealer that I require a new catalytic converter. I have actually heard that these parts do not normally go poor on their very own so ns am wondering what can reason a catalytic converter to walk bad? What must I call the dealer come look for and what need to I perform from here
That"s certainly true, usually failed converter is led to either by faulty oxygen sensors, dirty/faulty mass airflow (MAF) sensor or both.
vehicle starts and runs fine in the mornings or a one means trip come work about 20 to 30 mins 45 max, yet if imidiately try to return trip vehicle drops to about 20 come 25mph and also will not go any type of faster rpms redlines if permitted but speed continues to be the same, mechanic said transmission or a donate up cat an additional said it could be the computer, what is resulting in this problem?
If the rpm is redlining, the transmission is slipping. Is the ransmisison fluid level correct and condition good?Did you examine for trouble codes?
never investigated transmission beause, if it stops to remainder for about 10 to 20 mins it runs fine for around the very same amount the time

2001 Nissan Maxima GLE, 159,000 miles. 3.0L V6. This vehicle has been great, but over the past few years the "Check Engine" light has actually come on number of times. The very first time ns was called to operation a couple of tanks that premium fuel v the car and that worked, the irradiate went off and also it pass emissions inspection. The adhering to year this did no work and I had actually a diagnostic run that declared there to be a problem with the bank 1 catalyst system (PO420). One ar said it simply needed one ECM reset, according to your TSB, yet the Nissan dealer claimed no, that was no correct, there to be a brand-new TSB (NTB00-070b) that claimed to change the front pipe assembly and O2 sensor. I had this work-related done (not at Nissan) in 9/06 for $800 and a week later on the light to be on again. This time reportedly a PO430 password indicating a financial institution 2 issue. As I"d happen emissions ns waited till this year to attend to it. Now I"m hear two various stories indigenous two different Nissan certified dealer (both own by very same guy). One states I require a new Bank 2 converter, and also that the code shows it is no an O2 sensor issue. The various other states the this car really has only one converter, the others room resonators, and also that if the converter was replaced in 06 it can be an O2 sensor issue. He states you can not tell if it is cat or O2 native diagnostics, just from duty test. Feather at part manuals (wish I"d done this sooner!) ns think I have an idea exactly how this is laid out, but how can two different places have completely different concepts of the problem? reportedly the June 04 TSB stated repair could go either way. Reset ECM or replace front tube assembly (which shows up to include cat) relying on ECM part number. Now I"m wonder if I acquired ripped off and also ECM should have actually been reset, through no various other work. If you could let me know definitively and objectively what can be wrong v this and best means to proceed it would certainly be appreciated. As additional info. The auto is high mileage. In bad condition. And also needs about $1500 in suspension and also exhaust occupational IN enhancement to the above (which has actually been estimated at $750). PA has an emissions waiver ns might have the ability to get if I invest $150 on repairs ($79 diagnostic goes towards that), which can be O2 sensor however one dealer says that isn"t the problem so lock can"t execute that repair. Auto has been reliable and I yes, really didn"t desire a new car payment however is it time to provide up the ghost? I"ve do a donation for this reason if you could respond ASAP I would appreciate it.
