i got a camry 98 4cyl have
this code P0171 System to lean (bank1)
and
P1130 Manufacturer controlled fuel and air metering

what could be the problems?
hope you guys can help me out, thnx in advance!

 

Well lets see. Its got someting to with your fuel delivery/air intake. This could be a multitude of senseors etc. Did the person that ran the codes tell you anything else or is the car doing anything differently?

 

i got thhe code myself. the car seems to berunning normal, except for the engine light on....

Most likely you have a bad oxygen sensor. This would be the first oxygen sensor if you have more than one meaning the one closest to the engine and BEFORE the catalytic converter. They're pretty common and inexpensive enough where I'd recomend changing that first and see if the light goes out on it's own.

If it doesn't then bring it somewhere for diagnostic. Bringing it there first will end up costing you more for the sensor plus the time it took them to confirm it IF it is the sensor which it most likely is.

If you put a sensor in it and it doesn't fix it then you'd have to have it diagnosed plus be out whatever the sensor costs which is also bad but then at least you have a new sensor to show for it and most likely it WILL fix it. It's a risk either way but I recomend throwing a sensor at it first if its in the $100 price range.

Good luck and post back when it's fixed.

 

MAF...if its the o2 sensor is will usualy tell you o2 malfunction. got the same thing on an avalon and replacing the MAF fixed it.

Are you suggesting he replace the MAF sensor first? I'm pretty sure the O2 sensor is A LOT cheaper than the MAF sensor and if he's going to start throwing parts at it as opposed to paying high diagnostic charges then I'd recomend going with the cheapest possibilities first. I looked that code up on IATN and didn't get any hits on MAF's not to say that it dosn't happen cause I'm sure it does but I wouldn't say it's common enough to take a risk in replacing that first instead of a part that's much much cheaper.

 

i replaced all vaccum hose, and replace the intake pipe tube recently because i found out theres a crack.
so far my engine light is off

 

i have again an error this timeitsP1133 (manufacturer control fuel air metering)
what could be the problem for this code?

is this the o2 sensor in the front manifold?
