    okay so I had a code p0a08 and I replaced the inverter pump. I reset the code and I drove it. It shortly there after maybe 5 miles later it popped the check hybrid, I pulled over and pulled the codes, this time it says no codes. I cleared the invisible codes and everything is fine again for about 3 to 5 miles comes back on. I also had a newer AGM 12v that I swapped in and I got the same result. Can you tell if anybody else has had this happen and if so what was the fix?

    Thanks fellows..

    pump isn't OE and I think its half way working. The coolant in the reservoir is barely moving. I've never seen a good one so I don't know how volitile it should be but I'm guessing more than it has.,,

    I'm still getting the CHECK HYBRID but no code.

    if there's any movement with the car on and engine off, it should be okay, but idk for sure.

    looks like you'll need tech stream and sub codes. i would check the pump connector terminals for corrosion.
