I have a 2011 Volt and am getting the following error codes.

P1E00 - Hybrid Powertrain Control Module 2 Requested MIL Illumination

P26A7 - Engine Coolant Bypass Valve Position Sensor Circuit High Voltage

I used the VXDIAG VCX Nano for GM to clear the codes but they just come right back after next startup.

Vehicle is out of warranty and dealer wants $90 just to diagnose.

What would I need to change to fix this?

Thank you.
