Is it true that I can get a free catalytic converter if mine is messed up as long as it less than ten yrs old? I have an 05 nissan maxima. Usually emissionitems are warrantied for 80, miles but I don't know the timeline years wise. All you need to do is call a dealer and ask they will know. I was recently told by a nissan dealer that I need a new catalytic converter. I have heard that these parts do not usually go bad on their own so I am wondering what can cause a catalytic converter to go bad?
What should I tell the dealer to look for and what should I do from here Was this answer. Car starts and runs fine in the mornings or a one way trip to work about 20 to 30 mins 45 max, but if imidiately try to return trip car drops to about 20 to 25mph and will not go any faster rpms redlines if allowed but speed stays the same, mechanic said transmission or a backed up cat another said it could be the computer, what is causing this problem?
If the rpm is redlining, the transmission is slipping. Is the ransmisison fluid level correct and condition good? Did you check for trouble codes? Never investigated transmission beause, if it stops to rest for about 10 to 20 mins it runs fine for about the same amount of time Was this answer.
Then you should start and I would suggest getting a scan to check for trouble codes. This car has been great, but over the past few years the "Check Engine" light has come on several times. The first time I was told to run a few tanks of premium fuel through the car and that worked, the light went off and it passed emissions inspection. The following year this did not work and I had a diagnostic run that stated there was a problem with the Bank 1 catalyst system PO This time apparently a PO code indicating a Bank 2 issue.
As I'd passed emissions I waited until this year to deal with it. Using it regularly will help clear out those stubborn deposits and prevent new carbon build up from forming. Normally, you should be able to shine a light through a catalytic converter and see it coming out the other end.
If you can 't see a light shone on a converter from the other end, it means that it is plugged. Catalytic converters are a crucial component of your car's exhaust system. They're located under the car and attached to the exhaust pipe, typically with bolts.
All cars made after have catalytic converters , but some are more prone to theft. We recommend getting a direct-fit catalytic converter if your vehicle has an exhaust system that is still factory-fitted or OEM-styled. Universal converters do require any modifications to the system, but are made to fit a wide range of applications. These converters are generally cheaper than direct-fit converters. It Can Be Driven Indefinitely A plugged catalytic converter will only in extreme cases prevent you from driving your car.
You can usually drive your car indefinitely with a partially plugged converter , though you will see a drop in performance. P NISSAN Tech Notes As the code description implies the P code means that the vehicle's control module has detected that the three-way catalytic converter is not working properly is not as efficient as the factory is expecting.
The catalytic converter , which converts harmful emissions into harmless gas, often lasts 10 years or longer and should be replaced only when needed. It can become clogged, physically damaged, or contaminated by oil or engine coolant. It can also overheat. Catalytic converter replacement isn't cheap. No matter the situation, Advance Auto Parts has the Catalytic Converter product you desperately need. If I remember right the mechanic found the rear one has gone bad.
I will call to make sure it's that one. But for my question, why would I get that code if there's no O2 sensors after that specific catalytic converter. Am I wrong about not having O2 sensors after the last converter on my car? I sure hope I'm wrong because that would mean it's the one In the engine bay and not the one under the car. From what I understand I have two O2 sensors in the engine bay only. Please help and thank you in advance :.
Hi there - you are correct that there are 2 catalytic converters on your vehicle; one sometimes called a pre-catalyst that is part of the exhaust manifold, and a 2nd converter further "downstream" in the exhuast system. It is the 2nd converter that has oxygen sensors before and after, and usually triggers an "under-efficiency" issue. There is, however, a Nissan Recall Recall 03V on the "pre-converter" that is part of the exhaust manifold, and may be replaced under that Recall.
If you are unsure if this repair has been done, check with your Nissan dealer. If the 2nd converter does need to be replaced, I recommend a catalytic converter replacement performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.
