Question about 2001 Nissan Frontier Crew Cab

1 Answer

Catalytic Converters My boyfriend has a 2001 Nissan Frontier 4cyl. The check engine light came on and he got a diagnostic. He was told he needs to replace the catalytic converter. When he talked to the mechanic the guy told him he has to replace both of them. What are they called and where can we buy them? Would a mechanic be able to tell if they both need to be replaced without opening up the car and checking?

Yes any mechanic with a code scanner will be able to tell you if one or both are bad. each one has its own code. If it is a front cat then it should be a up stream cat and if it is the one further from the motor then it will be a down stream cat

before you go changing out the catalytic converter realize that the engine light comes on with only a few percent of the catalytic converter plugged - so before you change it, clan out the engine combustion chamber. i did this on my ford Taurus and with a $5 can of carb cleaner, it solved the problem

My nissan frontier crew cab 2001 SERVICE ENGINE SOON light on the dashboard kept flashing. Have serviced the engine, but the light won't stop flashing. Thanks


That means you have a failure somewhere in the system (Powertrain, Chassis, Body, Network). Just because the engine was serviced doesn't mean anything. You need to have the diagnostic codes pulled to determine what is causing the light to be triggered. Then correct the problem and the light will go out. If you just erase the light or code it wont solve anything.

Have had two catalytic converters go out in last 8 months


Catalytic converters should last the life of the vehicle. usually they are damaged be a poorly running engine. most common causes are lean misfire causing unburnt fuel and air to get into the convert and ignite there. coolant or oil burning. engine running too hot (lean) overheating converters.

was it the same converter that went twice? did they change them at the same time? where the pre-converters? is the engine light on?

Catalytic converters


If you are going to change the convertors I would just replace the first one closest to the engine. But when a computer code says "bank" they usually are refuring to the Oxygen sensor that is there , they are classified as bank 1 and bank 2. 1 being closest to the engine and 2 being farther down the exhaust. If its a computer code that told you bank 1 you might need to look at your oxygen sensor instead of your catalitic converter.
