Circuit/System Testing

Important: All modules must be powered down or misdiagnosis may result.

Ignition OFF, disconnect the scan tool and wait 60 seconds to ensure all modules are powered down.
Ignition OFF, disconnect the harness connector at the appropriate HO2S.
Ignition OFF, measure for less than 5 ohms resistance between the appropriate HO2S low signal circuit terminal A and ground.

If more than the specified range, test the appropriate HO2S low signal circuit for an open/high resistance. If the circuit tests normal, replace the ECM.

Ignition ON, verify the appropriate scan tool HO2S parameter is approximately 450 mV .

If more than the specified value, test the appropriate HO2S high signal circuit for a short to voltage. If the circuit tests normal, replace the ECM.
If less than the specified value, test the appropriate HO2S high signal circuit for a short to ground. If the circuit tests normal, replace the ECM.

Ignition ON, install a 3A fused jumper wire at the HO2S high signal circuit terminal B. Toggle the jumper wire between the HO2S low signal circuit terminal A and battery voltage. Verify the appropriate scan tool HO2S parameter toggles between 0 mV and approximately 1,000 mV .

If the appropriate scan tool HO2S parameter does not toggle correctly, test the HO2S high signal circuit for an open/high resistance. If the circuits test normal, replace the ECM.

If all circuits test normal, replace the appropriate HO2S.

 

yea,it was crazy. this girl was on vandalia (where the last big bust was) and there was a bunch of people there and this chick flew down vandalia and blew a red light doing about 80mph and hit this guy on the corner waiting for the bus. **** was crazy. but it sounds like last weekend there was some decent racing goin on.

hopefully the weather holds out and we can witness some

 

I'm sure it will, also planing on going to the fair grounds tomorrow to with the wife and friends

 

Thanks Ryan, I will look into that. Now for some reason it's been off all day today though...strange...I'll climb under there and see if anything is loose or what is going on.

 

Hey if your available get over here to the holiday off 280 need more Balts out here.

 

IIRC that code is a rationality check code. basically checking to make sure the sensor does what it needs to do in an allotted time.. I'd probably just replace the sensor

 

i used to go out there all the time but kinda faded away from that, my buddies try to get me to go too. i kinda want to get out that way again because of all the new fast projects coming out of the woodworks.

 

oh hai

Ryan = the awesome, gives really good reach-a-rounds.

 

Powercruise was ******* awesome!

bryce was there and another yellow cobalt with a CF hood

 

Speaking of.. Your car done yet? I got an itch to tune!

 

no... there was a "mishap" with UPS, someone was stealing boxes and mine containing my pulley assembly happened to be one of them. I was told that the box was found and it was shipped back to the seller. Seller said he shipped it out over the weekend.

hopefully i get those soon.

then i have to get a new H/E, cuz rolling around w/ the leaky one i have now is stupid.

sad

 

all you MFers better be at powercruise next year

 

Hey nhanson sorry i couldnt make it i was down at carcraft summer nationals this year. And also Ryze what kind of tuner are you and how much is it for a tune, i would really like one so i can beat more people around here

 

lol. I can tune cars.

 

oh hai!

 

yea hopefully next year they will be different weekends.

Driving the **** out of your car>looking at cars

 

Hey ryae what kind of tuner. HP trifecta what up? And how much. Yeah could be but I was looking at the classics I wanna get. I can't afford it if car breaks lol

 

HPTuners..

PM me if you want details.

 

Ryan, I'm going to have you do the following for me: front sway, new header, new dp. Also, if you can check to see if my cat-back has a leak in it (possibly patch it up) and lastly, replace my the second 02 sensor for me.

I know these aren't hard to do, but I'm lazy and would rather pay you. LOL

I'm ordering everything online right now and will let you know when I get it in. After I get it all, we'll figure out a day/time for you to do the work.

Thanks I appreciate it.

 

Anybody live near Esko Mn????

 

why is there a prostitute you want me to try?

 

Yup, 44 years old:

 

anyone around saint paul know where to get GOOD premium gas? it seems like every gas station i go to has shitty 91 octane gas. everyone says shell gas is amazing and stuff but i found 1 shell gas station and it has 91 octane gas! i have to run premium so i was just wondering if anyone around saint paul know where to get good gas?

 

Bp 93 works good.

 

bp 93 everywhere in minneapolis.
