soo today i get into my car to drive to school and the Fing check engine light came on for no reason i had 2 codes cleared about a month ago and was thinking that they came back? heheh
the codes i got back then were

P1196 MANUFACTURER CONTROL FUEL AIR METERING
P1426 MANUFACTURER CONTROL AUXILIARY EMISSION CONTROL
REC DEALER SERVICE

does anyone know what the coeds might mean?
i will try to get it scanned asp and see if i get the same codes now

 

Sounds like a MAF or O2 sensor issue based on the first code, and if it's malfunctioning, emissions will be messed up too.

 

how much would the parts cost? and is it considered a DIY?

 

Factory O2 sensors are about $150 and a universal splice-in Bosch sensor is about $70. The MAF I'm not sure (check www.ecstuning.com). Both are definite DIY fixes.

 

BTW, don't take that diagnosis as gospel - that's just what it sounds like to me. Type those codes into Search here and see what comes up from various threads where others had those issues.

 

so i just came back from pepboys and i got some codes
p1196 O2 Sensor heater circuit electrical malfunction (Bank1 Sensor1)
P1426 Tank Vent Valve Oopen
P0134 O2 Sensor CKT no activity (Bank1 Sensor1)
does anyone know anything about my codes?

 

You've got a fume leak on your fuel system (may just be the gas cap), and your primary O2 sensor is dead (it's not heating up as it needs to, or sending signals, in order to reliably send info to the ECU). Reseal the gas cap, change the pre-cat O2 sensor, clear the codes, and see what happens.

 

how do i reseal the gas cap? can it be something connected with getting the fuel level sending unit done? because i had to open the thing in the trunk
and is there a DIY for changing the pre-cat O2 sensor?

 

is this the O2 sensor that i need? http://www.autopartswarehouse.com/de...USOS-1000.html

 

dude for the front o2 sensor just trace the wire unplug it and pull the wire so its freed up (may have to cut some zipties) and get a wrench and take it out its not hard at all ive taken mine out and replaced them alot since i have a test pipe i tend to eat o2 sensors about once a year for some reason
