Hello,
today finally got my Maxima for inspection ( DMV). And was shut down by these emission problem codes : P0420 and P1130.
Any ideas where to lookup for description and how bad is this ?
Is this covered under warranty ?
thank you



Ok. I found smth. :
P0420 Catalyst Efficiency Low Fault Bank A
P1130 Oxygen Sensor Fuel Trim at Limit *codes* A U

*Codes* are used to identify the 4 Oxygen Sensors
A= Bank A of the engine. Cylinder #1 is located on Engine Bank A
B= Bank B of the engine.
U= Upstream of the Catalytic Converter
D= Downstream of the Catalytic Converter

Same codes for the Infiniti:

P1130 Swirl Control Valve Control Solenoid Valve

Ok/. Now the question remains :
what to do ?
is this covered ?
