'Sensor power supply' is a separate J2012 family next to the 5 V sensor reference (P0697 ff): an additional supply from the module for sensors or drivers – in GM hybrids a 15 V supply for resolvers and inverter gate drivers, there as supplies A and B. Supply C is a third such circuit. P06E7 means the voltage of supply C is too low – a short to ground, an overload from a supplied sensor or a failed regulator; Mitsubishi marks it as a short-to-ground sub-code. Open circuit and high are P06E6/P06E8. Only Mitsubishi's 2022 Outlander lists P06E6 as a main code with sub-codes for low and high, called internal control module, without thresholds or the sensors fed. All sensors on the circuit then deliver invalid values, so several follow-up codes and limp mode are possible.

Likely causes

Short to ground in the supply wire or a supplied sensor
Supply regulator inside the module faulty
Connector problem in the supply circuit
Vehicle undervoltage

Symptoms

  • Check engine light
  • Several sensor codes at the same time
  • Limp mode or reduced power possible
  • Possibly starting problems or rough running
