hi guys, my 06 s2k's Malfunction Indicator Lamp yesterday night while i was driving back home, and i went to pepboys this morning to pull out the codes,

the codes are P1172 and P2A00, which represents air fuel sensor [sensor 1] circuit out of range, high and air fuel sensor [sensor 1] circuit range/performance problem

the guys from pepboys told me should something wrong with the o2 sensor, the one on the front, but i read the owner's manual said might be loose fuel cap
I got no idea wat is going on now, can you guys help me out with the codes and solutions?

thanks
Rex

 

loose fuel cap takes a certain amount of mileage to come off. also the 06 had a tsb for a bad tune from the factory. that caused too much condensation on start up and would mess up the O2 sensor and the condensation would later on mess up your catalytic converter as well. on the 06 ap2 you will get a fuel cap message on your dash not a CEL. and this message will flash until drive cycle is complete. forgot how long it took. how many miles do you have on your car? the TSB is here somewhere print it out and take it to a dealer.

 

Get the updated front o2 from Honda and that is it.

 

my car only has like 32k miles on it, but the light didnt flash at all, just stays on there
so does that mean is the o2 sensor's problem?

 

do i really have to like buy from Honda dealer for that o2 sensor? or can i get aftermarket one?
does Honda dealer have to undate the computer instead just replace the sensor?

 

You have lucked out in that the best S2000 mechanic on the board has given you direction. replace the noted sensor. Check Majestic Honda as they are a good supplier.

i agree.
When Bill says "jump" you ask "how high?"

 

O2 sensor is an easy diy. Buy it from honda online (Majestic, etc), then replace it yourself.

You'll want to buy an O2 sensor socket from like Autozone. Makes it a lot easier to loosen the old one.

All you do is unplug the sensor, remove old, screw in new and tighten, plug in new sensor.

 

you shouldnt have to buy it, i think it will be replaced under warranty?

 

got ya, thanks
