98 Camry 3 CEL Codes

[njdhockey30]

Hey I'm new to the boards so forgive me if this has been tackled already. I have a 98 (4 cyl engine) and the check engine light was on and I went to AutoZone to get the codes read and this is what I got:

P0171-System too Lean
P1130-Air/Fuel Sensor Circuit Range/Performance (Bank 1 Sensor 1)
P1133-Air/Fuel Sensor Circuit Response (Bank 1 Sensor 1)

Anyone ever have similar problems or know what could be wrong?

Thanks in Advance.

It could be your OS sensor needs replacing i had the same problem

They alll lead to the oxygen sensor. It's the sensor in the manifold.

Don't be in rush to replace the O2 sensors just yet. Your "Sytem too lean" code is the first issue to deal with. Check your rubber intake pipe that goes from the air box to the throttle body. The pipe can crack and let in extra air. Also check that all your vacuum lines are properly attached.

Thanks for all the help, guys. I really hope it's not the O2 sensor, since it was just replaced in 2004. I think it was replaced with an after market sensor, so I guess that could be it, though. I'll check the intake pipe and the vacuum lines and report back. Thanks again. I'm due for my NY inspection in July so I just want to get it taken care of to pass the inspection (automatic fail in NY if CEL is on).
