Check engine light P1E00

[Cheezecake]

Stopped by the local Walmart last night for a DCFC charge, on the way home the engine light came up. Ran the codes and showed up as P1E00. I searched online and the forum and found a few posts about it, but nothing concrete with respect to the Spark. OBDII scanner says it is related to the HPCM2. Was able to drive home and to work today with no problems. Last time I did a fast charge was about 5 days ago and no issues then.

Scheduled to drop off the EV on Friday. It's the 2015 model with 27k miles, so it should be under warranty. Anyone with similar issues before? I'll post updates once I hear back from Chevy.

I got a P1E00 and a P1F58 fault. I have a 2015 with about 34K miles (purchased used from Carvana at 29K miles).

Was about to call the dealer, but Googled and found this:

I had purchased a 12V AGM battery but hadn't replaced it because the existing one looked so new (even though Carvana's sheet didn't mention it being replaced).

I changed out the battery in 5 minutes and the faults disappeared.

Fingers crossed that that was all that was needed.

Something wonky on your Spark EV? Test (voltage AND load test) the 12V accessory battery first!

And invest in a good, SMART (does de-sulfation and auto-stop-charge) trickle charger, and use it once or twice a month, overnight.

Thanks for all the inputs. I forgot to post an update. Went to the dealership...they "threatened" a $100 diagnostic fee if it wasn't warranty related...turns out it was a warranty issue and was indeed the HPCM2, so it was replaced on them. Been running trouble-free ever since.

The P1E00 code caught my attention. In November 2017, the yellow Service Vehicle Soon light came on in my leased 2015 Spark EV 2LT. I took the car to the Chevy dealer and they found P1E00, Hybrid 2 P3009 and P3023 codes. Short version of a long story - the dealer said it was a problem with the battery charger control module so they replaced it. The part number was 23453239 Module 2.211 Y. I never had another problem after the repair but the car lost about 1.5 kwh of battery capacity at the time the light first came on. I no longer have the car as it was leased and the lease ended in May 2018.

the problem came back.

Dealership diagnosed it as N5907 Electric Drive Motor Coolant Flow Control valuve. GM Part # 95072566

I still have coverage under my transferable powertrain warranty but dealership claims this is not covered.

"Electric Drive Motor" sure sounds like powertrain to me!

Anyone have definitive info on this? This code (P1E00) is showing up on my 2015 LT2 with ~47K on it. I replaced the 12V battery recently (< 12 months ago) with what I think is a compatible model just a few months ago so I am hoping that it is not a 12V battery issue.

From reading above, what exactly is the HPCM2? And is the Electric Drive Motor Coolant Flow Control valve related to it?

Not all 12V batteries will work correctly in the Spark EV. I know batteries that are not AGM will more likely cause problems. Here is a link to as discussion thread on 12V batteries here. https://www.mychevysparkev.com/threads/spark-ev-12-volt-battery.4938/

If you got the error after a failed attempt at DC Fast charging try disconnecting the negative cable from the 12 volt battery and leave it disconnected for 30 seconds to a minute or so. This will reboot the EVs computer and should clear the error code if it was caused by a failed charging attempt. I used to get them all the time at Electrify America chargers. This type of error from failed charging is no big deal. It won't come back till the next failed attempt.

The P1E00 check engine light has haunted me for many years on my 2016 Spark EV. I think it’s a thing of the past now.
By topping off the blocked coolant reservoir (the 1 with the guard ) and holding the power button on startup until the gauge cluster lights turn off at startup.
I was reading posts from here and other sources for quite some time and pieced information together. By topping off the reservoir it think it helped with a sensor as with the volt. I added more until it reached the top of the embossed image of the manual ( the open book image).
The other thing I check was the 12 v battery. It was in normal working condition. At one point I wondered if the relay to turn the car on was causing issues so I decided to hold the button down longer rather than a quick touch and go. I decided to be consistent about holding it down until the lights in the cluster turned off. I especially focus on the check engine icon.
I’ve been monitoring the consistency of this technique and so far so good. I started using this routine about 6 months ago after clearing the codes one last time. I tried to get the codes to surface again by driving in high temps and restarting car after short trips. The only way I was able to recreate the P1E00 code was by quickly pressing the start button after an initial 5 minute trip to the grocery store. After this test, I cleared the code. Pressed start using my new technique and it’s working without issue. I hope this can help someone.

@broken spark had a similar problem with P1E00 and some other codes which caused a no-start condition (high voltage system lockout) over at https://www.mychevysparkev.com/threads/spark-ev-died-while-driving.9529/
Resolved by reprogramming the HPCM2 with a VCX Nano and AC Delco TDS subscription (40 USD for 24 months)
