P06DEEngine Oil Pressure Control Circuit Stuck On
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Can trigger limp mode
- How the car detects it
- A switchable oil pump changes its output via a solenoid valve; powered it runs at the low stage. To test it, the module switches the pump between stages (GM up to 15 times, with oil at 50–110 °C and 1350–2500 rpm, expecting more than 100 kPa difference) and watches the oil pressure sensor; Ford checks each switch-over of a two-stage pump within 1 s, or a variable pump over 10 s, from 30 s after start. P06DE is the counterpart of P06DD: the commanded high stage is not reached and the pressure stays below the threshold, as if the valve were stuck on. Too little oil pressure at high load endangers the engine, so GM sets it after just one trip; a Ford patent raises idle speed in this case. A short to ground on the control wire (P06DB) has the same effect electrically. An FCA bulletin for the 3.6 L V6 fixes false codes by software.
