P06E6Sensor Power Supply C Circuit/Open
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- '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. P06E6 is the general or open-circuit code of supply C: the module measures the output of its supply regulator and finds the voltage missing. Low and high are P06E7/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.
- What you may notice
- Check engine light
- Several sensor codes at the same time
- Limp mode or reduced power possible
- Possibly starting problems or rough running
- Likely causes
- LikelyOpen circuit or connector problem in the supply circuit
- PossibleShort in the supply wire or a supplied sensor
- PossibleSupply regulator inside the module faulty
- RareVehicle under- or overvoltage
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
