Hello all !

This morning was very cold (-12C, 10F). When starting my car, the check engine light came on. The gas engine was running. I scanned it with my OBDII tool and i get two P1E00 '' Hybrid powertrain Control module'' codes.

It's the second time it does that. I previously erased codes 2 weeks ago and it only came back with a similar very cold temperature.

What would you guys check first ? Coolant level maybee ?

Thanks in advance and have a great day !

10F is not very cold really. You shouldn't get check engine lights when starting under these temperatures (or any temperature, for that matter). What were the specific codes?

10 isn't cold by colorado standards, let alone most of canada.
I have had no problems down to -15F, but my charger has.

Hello, thanks for your reply. I have no other specific OBDII codes than P1E00, and it is listed 2 times...

I would let it cool off again, and check the battery coolant level. (reservoir on the left) The first time I had a problem with low coolant level was the first time it got to about that temperature, and I think now it may have been contraction due to the cold. Later it was more consistent and I had it topped off at the dealer and the codes cleared, as did most of us with early model year Volts. Best not to do it yourself.

It could well be something else, but it's an easy check and an easy fix if that's the problem. It also won't take long to cool down in this weather.

It's impossible to know what the issue may have been without the other code, the P1E00 is just the generic "light up the check engine light" code.

Any chance you have a GM dealer nearby wiling to read the codes for free or cheap? (I assume you don't have OnStar free service, or you could just press the Blue button and have them tell you the codes. They normally just give a description of the problem but if you ask specifically for the DTC's they'll give you the numbers).

Did you have any other messages in your car that were unusual?

That's bizarre. P1E00 should always be accompanied by another code, which is the actual issue the computer saw.

I had no problems with -25F 2 weeks ago and I deliberately parked outside without a EVSE.

I DID have a lot of frost on the windshield and "reduced propulsion" from the cold battery, but no code.

2013 Volt. Wife said would not auto start this AM it was -13F. It did start with the button. After work, it would auto start but, she noticed on way home check eng light on.
I just went out tonight and started it and the check engine light was on And the the car was calling someone on its own ??( i do not have onstar nor my phone in the car) . A lady answered but did not identify her self as onstar and could not hear me, so I hung up. Looked at the center info to see if it would say anything about the check engine light ( forgetting that that would have made too much sense for GM to actually tell you the code) and it called her AGAIN. same lady that could not hear me so I hung up and it called again. Hung up and shut off car.
Anyone have similar experiances?

UPDATE -2F this AM started fine no check eng light and did not try to call on it's own. However when I got into; it double honked. Anyway WHew seems OK. Still concerned. Looked on MyVolt and it shows no issues in diagnostics section-if that even works on the web sight. I'll just have to pull codes at the dealer Monday see what they say.

a quick double-honk is "key left in car", which if you got into it after it was previously running, would be in fact true and only confused about that you were ALSO in the car.

Coolant level ok !
I guess it's something else. Too bad my INNOVA code reader doesn't tell me more...
I reset the code and it didn't came back on another cold start. It comes and goes !

Even when this cold it should be well above the seam. If it's not the level, then do you have a remote charge door opener and has it been working properly? This will also throw an intermittent code, and was a common problem before MY 2014.

Really, though, I would take it to a Volt-qualified dealer and have them diagnose it. You don't say where you are, but there are a number of them in the major cities.

Mine was using Onstar to call a much younger Bolt. All I heard was "Tell me I'm a dirty ICE again!!!!" My phone bill was very high that month.

News from my visit to the dealer : it's got a P0D3F MIL code... The dealer reprogrammed the BCCM (charger) and it came back this evening. It seems to be linked with cold and humid temp...
Last night, it got cold (-14C) in a short matter of time. I checked the outlet voltage and I have 116V, pretty stable. I also noticed that the charge door tends to stick when closed, gets frozen and ''glued'' there

I doubt it is related to cold or damp. See WopOnTour's post #13 in this thread:

http://gm-volt.com/forum/showthread.php?151769-Error-Codes-P0D3F-P1E00-Software-Update-PIC5803C-New-12-Volt-Battery/page2

It's more likely to be tied to an interruption in charging, for whatever reason. I thought it seemed familiar, the quoted post was useful to me some time ago.

The sticky charge door can have a number of causes, depending on the model year and the circumstances. The simplest is a quick freeze when it has been damp - try some silicone spray.

Well ! some good news !

I inspected the 120V exterior outlet in which the car is plugged and it showed signs of humidity/corrosion inside ! I think your point of the charge interruption is to be considered. I changed the waterproof enclosure, and the outlet for new ones. The MIL did not come back again...

That is good news - I hope you will now have as many trouble-free years with your Volt as I have had with mine. Next up: go to Level 2 charging. Ontario will help you out with the cost, so will some other provinces.
