Check engine light P1E00

Wed May 01, 2019 9:06 am

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: ... s-response

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.
