Alright so I work at Richard Chevrolet in Cheshire at the body shop and i've been having my check engine light on for quite some time. I got it checked out by one of the guys in the service area and pulled up quite a few codes. If anyone could help me out i'd appreciate it.

Alright so hear are the codes:

ECM
-P0411 - ?
-P0128 - Coolant temp low
-P0300 - Misfire

TCM
-P0961 - Line pressure solenoid
I belive this may be from using my shift plus. If so is this horrible to have on my car now. I havent used the shift plus in weeks now.

Radio/SIR
-B1325 - ? Im not sure what that means but my two front speakers dont work besides when the passanger front comes on every so often.

 

you work at a chevy dealer, we're talking to the guys, and didn't ask them what it meant?

 

Diddo

 

The tech I talked to didnt tell me much but to check stuff out online because hes crammed with work. Just asking to see what the forum has to say.

What a turd. 411 i belive is an evap code, the coolant temp low means change your tstat and flush the coolant. I just had that. As for the missfire it code be due to the car running rich from seeing low coolant temp. Clear it out and see if it comes back.
As far as the trans code i don't know. The other one is a body code of some sort.

 

hm. i thought people were saying that shiftplus didn't **** with the trans solenoids at all?

good thing i had vince tune my transmission. lol

 

how much of a difference did the trans tune make from stock? is there a smooth or abrubt shift? ive been thinking about doing that

thanks, ill flush my coolant and then clear out the light. ill see if it comes up again. thanks

 

its not as harsh as it sounds the shiftplus is on the highest setting but from what i gather it shifts pretty damn fast.

i love it compared to stock. it's willing to drop a cog with a small jab of the throttle much unlike stock where it hesitated for like 3 seconds kinda asking you if you were sure you wanted to punch it. lol

i figured ah what the hell and got the trans tune when i got my trifecta tune and i have been happy ever since and haven't had a transmission related CEL since i got the tune in May.

 

Not to sound like a jackass but google works for codes too:
read the first post.

 

haha thanks, its my secondary air filter or secondary air injection something is clogged.

 

Yep, your sai is clogged or inopperative.

ECM
-P0411 - Means youre secondary isnt flowing enough, could be **** in the tubes, air pump inop(blown fuse or water in pump are common)
-P0128 -Coolant temp low, make sure you coolant level is proper, low coolant will set this, so will a bad coolant temp sensor, or a bad t-stat. Coolant condition cant cause this
-P0300 - Misfire, yup. unless youre noticing a miss I would just make sure youre being vigialnt with your maintenance, TB service, good fuel, clean filters, spark plugs if over 50k

TCM
-P0961 - Line pressure solenoid, if the solenoid or its circuits are open or shorted this sets. If its current and casuing issues then youll probably be banging shifts. if its shifting normally, the code is old, clear it.


Radio/SIR
-B1325 -This is a voltage out of range error, there should be an additional code (03 or 07) that goes with it which tells whether it saw too high a voltage or too low a voltage. Clear the code, if it comes back check power and ground and conections at the radio, if the voltage and terminals are normal you need a radio.

 

thanks alot maven, you just made everything so much easier
