The only codes my car was throwing was the P0069 and P0420 code. Would the fuse be burnt up if it was bad? I might take it to the dealership after its running to have them look at it.

 

well, aside from any wiring problems....the p0069 you should inspect the Baro sensor, the SCIP sensor housing for cracks or damage....The P0069 will lead to either a faulty Baro, SCIP or a PCM....However I would look into the Catalytic converter code first. If the converter isn't functioning properly that would cause the car to run like **** and possibly set off some other codes.

 

I have no cat on my downpipe and also i remember Laz having a problem tuning my car a few times where it froze up the HPTuners software because it couldn't load the new tune into the VCM. Ill be able to drive the car friday but I cant floor it until i figure out what is wrong with this car...

It's been said a couple times also that i have a lemon

 

The p0420 code is not applicable in your situation. The reason it is set is due to no cat. It sees the Front o2 and rear o2 readings identical indicating the cat is not doing its job. Its not there though so thats why it sets. The p0069 code is a map code. This happens in alot of heavily modded cobalts, if you have HPtuners just turn off the test. Heres a description of the code.

DTC P0069
Circuit Description

The barometric pressure (BARO) sensor measures the pressure of the atmosphere. This pressure is affected by altitude and weather conditions. A diaphragm within the BARO sensor is displaced by the pressure changes that occur from varying altitudes and weather conditions. The sensor translates this diaphragm action into the voltage signal input that is used by the powertrain control module (PCM) for diagnostics and emissions control.

The supercharger inlet pressure (SCIP) sensor measures both the atmospheric pressure and the vacuum that exists under different operating conditions in the supercharger intake plenum. The plenum volume between the throttle body (TB) and the supercharger is where this sensor is located, and for the purpose of this diagnostic, this area is considered to be the intake manifold. The diaphragm within the SCIP sensor functions in the same manner as the BARO sensor. The sensors are not interchangeable. The actual measurement from the SCIP sensor is used by the PCM to calculate the difference continuously between BARO and SCIP. The calculated difference is displayed as the SC Inlet Pressure parameter.

The purpose of this diagnostic is to analyze the correlation between the BARO sensor, and the SCIP sensor. This is accomplished by comparing the difference between BARO and SCIP at key ON, engine OFF (KOEO), at closed throttle idle conditions, and at wide open throttle update events. At KOEO the difference between BARO and SCIP is represented on the scan tool by the SC Inlet Pressure parameter as a value that should be very close to zero. A negative SC Inlet Pressure parameter means that the BARO sensor value is less than the SCIP value. A positive SC Inlet Pressure parameter represents a BARO sensor value that is more than the SCIP value.

At idle the SC Inlet Pressure parameter represents the calculated difference between BARO and the reduced pressure that is present in the supercharger intake plenum as a positive value. At wide open throttle the SC Inlet Pressure parameter represents the calculated difference between BARO and the increased pressure that is present in the supercharger intake plenum, and should be very close to zero.

Both sensors have the following types of circuits:

* A PCM supplied and regulated 5-volt reference circuit
* A PCM supplied ground for the low reference circuit
* A sensor signal circuit that supplies a voltage input to the PCM

Changes in BARO due to weather are relatively small, while changes due to altitude are significant. Pressure can range from 56 kPa at an altitude of 4267 meters (14,000 feet), to 104 kPa at or below sea level.

If the PCM detects that the BARO sensor signal and the SCIP sensor signal are not within a calibrated range of each other, whether that value is negative or positive, DTC P0069 sets.

Ok in Lamen terms could you explain that to me so i can understand easier lol Are you saying HPTuners can fix this?

 

ya i think i fucked my **** up too car sounds deeper and my supercharger is prolly fucked ya 3rd-4th was 3rd to 2nd and stayed in second for about 2 seconds so .................................................. ..............I FUKED UP the cel stayed on for 2 quick flashes and on top of all that i was racing a camaro ss and it put about 3 cars on me from 60-100 and i got to 105 and shifted into FUKIN 2nd i meant 4th but oh no the ****** never hesitated to let me slide right on into it so no smoke i think maybe i might of flooded the valves a lil but 2 quick cels and then nothing car runs fine just sounds deeper like it has a touring exhaust instead of my performance exhaust

wat the hell do i do now if i take it to the dealership they'll know for sure that i tacked that bitch past 8 imean it was fukin sittin on 8grand man maybe when my friend gets hptuners then i'll have him check it maybe he could even delete it off the pcm where i fuked it up and gm will never know hahahaha, but that just ain't gonna be that easy so waton earth could i do guys any suggestions please guys i know its driver error but damn it let me easily go into gear why didn't just block it so it has no chnace like when u have to rev it up 1st for it to slide in easier, this is bad. help

 

Wow. Go back to English 1. Also, your a ******* idiot.

 

 

 

wow I smell bent valve or broken follower on that one

 

um..ya..ummmmm uhhhh........what?

 

never took it, App LA all through school never learned to read unti i was in 7th grade

 

That explains so much.

 

that's pretty bad man
