Hi Everyone, Gen 1-2011 Today I received a load of error codes relating to O2 Sensor issues, seemingly the Bank 1 Sensor 2, or from what I can tell, the downstream sensor post catalytic converter. I figure I'd try to replace the sensor before taking it to a shop, but I'm having difficulty...

Hey Everyone, Today I received the what-seems-to-be-common issue of my ABS faulting, causing low traction warnings and a "service stabilitrack & brake assist" warnings. A couple things, how common is it that it's simply the sensor for front passenger wheel? In conjunction with the low traction...

Hello, I am having issues with my Volt which is starting to get frustrating. About a month ago I had a DTC code shown "P06DE" Engine Oil Pressure Control Circuit Stuck On Confirmed". It would then state on the dash "Reduced Propulsion Mode" however it never lost any power. This coded cleared...

Major DTCs when dolly towing 2018 Volt See DTCs below The owners manual states that you can dolly tow the 2018 Volt with front wheels up. It says place in park with ebrake off. Every time I start my Volt after towing it, the CEL is lit. I get the message that stabilitrak is unavailable...

I just bought my 2015 premium second hand (from the dealer) just under 2 weeks ago, so i'm still getting used to things. 2 days ago, after an intermediate stop on a 2-hour drive, my check engine light came on. i pressed the onstar button, and asked about the error. i was told that it was the...

Hi everybody ! 2012 Volt here with 110 000km (68750mi) I installed my winter tires and backing up from the driveway, the ABS warning (ABS maintenance) came on. Took it to GM and Dealer tells me it's either the ABS valve (1400$ plus labor) or the ABS control module. Also, after I went home...

Hi all, I have a 2014 Volt and it's been trouble free but now for the past two days I'm experiencing something unexpected. The first time this happened was two days ago. I came to a stop light and my Volt just stopped moving. I was able to shut it down and fire it back up but the check engine...

Hi All, I'm fairly new to Volt ownership, I purchased a used 2012 Volt around July of this year with 42k miles, I took a trip last week with the family from NYC - Niagara CA - Toronto - Montreal - Lake George- Back to NYC around 1,900 miles total for 5 days. All driving except the first 34...

We have all seen many posts on this forum about obd2 readers, leaving them connected to the OBD2 port and gaining all kinds of information from the Volt. What I cannot find is this : Is there an OBD2 reader or scanner I can purchase that will give me the same info that OnStar can give me when...

Hi all, Really big Thank you to John - the Volt tech at my dealer GWS for updating the software modules to fix my intermittent DTC's POD3E as fixed in the USA on service bulletin PIC-5803-B "(This controller update is a part of a coordinated Vehicle Software Configuration Management update...

Went to drive my brand new (<300mi) Volt today and found the Engine lamp lit. It still ran fine, so I went driving. I called OnStar while driving and they did a remote diagnostic (while I was driving) and told me it was the P1E00 and P0D22 codes: P1E00 - "The Vehicle's electric system is...

Tonight after stopping to buy gas (grrrr - another story) I notice the Check Engine Light was on after starting back on the highway. I called OnStar and they read back two codes P0CCF and P1E00. The second is a generic code, and the first, according to OnStar, is something like "battery...

My engine light came on today. I called Onstar and they ran diagnostics but didn't find anything. I came home and saw P1F0B (& associated P1E00) on my ScanGuage. I reset them. Later I was out and called Onstar who transferd me to the "diagnostics center". They ran diagnoistics again but...
