4 codes from my ECU today...

[boro]

So let me make sure I checked these correctly.

Code 1: 1 1 1 1 5 = Code 45: Atmospheric Pressure Sensor Faulty
(I knew that because I accidentally broke the vac nipple off of it yesterday.. )

and/or

Pressure sensor and pressure exchange solenoid valve Faulty sensor or pressure exchange solenoid valve inoperative


Code 2: 1 1 1 1 9 = Code 45: Improper MAF
(this is the one I just bouht from americanyouth)


Code 3: 1 1 1 or 1 1 2 = Code 21 or 22. I can't tell because it flashes so fast: Knock Sensor or Water Temp Sensor faulty or reading abnormalities


Code 4: 1 1 3 = Code 23: Air flow sensor. Abnormal voltage input entered from air flow sensor.



This should be a fun adventure!

maybe the alternator is dead, no abs light or no abs all together. Check out ur battery voltage, and of course, check out your ground

Did you post on the correct thread? Alternator? Ground Cables?
My car still runs....just hiccups and misfires alot!
And now after about 45 seconds of driving I get a CEL. So I checked the codes and this is what I got.

lol, i did, check out the voltage, and ground cable, i have had random CEL's was just my ground cable, another time it was my altnerator died.

its not random I don't think. It has been running very rough for about 3 weeks now. If I go into boost at all, and some times even when I don't, it pings and misfires to all hell. It started doing that during a huge snow storm here in sub freezing temps when I was low on gas, one night. Heet seemed to fix it. Just poured a bottle or two of heet in when I got gas. Then it over heated one day and the motor started shaking and quaking severely, loss of power, hiccuping and pinging all over the place... Then just today I get a CEL going to work!

Satrday I put on a different MAF, and moved it closer to the throttle body. At the same time I accidentally broke the vaccum switcher for the pressure sensor...oops.

Did you reset the ECU after you installed the new MAF? Was the new MAF the same as your old MAF (i.e. plastic maf or metal maf)? If you still have your old maf it may still be good...try cleaning the elements VERY carefully with a cotton swab and some alcohol. Be very gentle.

I got all the same codes when I was out of time. It's easy to check.

Do both of those and let us know where your at.
