DTC P06DC

  • Engine Oil Pressure Control Solenoid Valve Control Circuit High Voltage
  • Circuit/System Verification
  • Ignition ON.
  • Verify the parameters listed below do not display Malfunction when commanding the Engine Oil Pressure Control Solenoid Valve ON and OFF with a scan tool.
    • Engine Oil Pressure Control Solenoid Valve Control Circuit Low Voltage Test Status
    • Engine Oil Pressure Control Solenoid Valve Control Circuit Open Test Status
    • Engine Oil Pressure Control Solenoid Valve Control Circuit High Voltage Test Status
  • ¤If Malfunction is displayed

    Refer to Circuit/System Testing.

    ¤If Malfunction is not displayed

  • Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
  • Verify the DTC does not set.
  • ¤If any DTC sets

    Refer to Circuit/System Testing.

    ¤If the DTC does not set

  • All OK.
  • Circuit/System Testing

  • Ignition OFF, disconnect the harness connector at the Q44 Engine Oil Pressure Control Solenoid Valve, ignition ON.
  • Verify that a test lamp illuminates between the ignition circuit terminal 1 and ground.
  • ¤If the test lamp does not illuminate and the circuit fuse is good

  • Ignition OFF, remove the test lamp.
  • Test for less than 2 ohms in the ignition circuit end to end.
  • ¤If 2 ohms or greater, repair the open/high resistance in the circuit.

    ¤If less than 2 ohms verify the fuse is not open and there is voltage at the fuse.

    ¤If the test lamp does not illuminate and the circuit fuse is open

  • Ignition OFF, remove the test lamp.
  • Note: An internal short in any component supplied by the fuse may cause the fuse to open and set a DTC when the component is activated.

  • Test for infinite resistance between the ignition circuit and ground
  • ¤If less than infinite resistance, repair the short to ground in the circuit.

    ¤If infinite resistance, test all the components connected to fuse and replace as necessary.

    ¤If the test lamp illuminates

  • Verify that a test lamp does not illuminate between the ignition circuit terminal 1 and the control circuit terminal 2.
  • ¤If the test lamp illuminates

  • Ignition OFF, disconnect the harness connector at the K20 Engine Control Module.
  • Test for infinite resistance between the control circuit and ground.
  • ¤If less than infinite resistance, repair the short to ground on the circuit.

    ¤If infinite resistance, replace the K20 Engine Control Module.

    ¤If the test lamp does not illuminate

  • Remove the test lamp, command the Q44 Engine Oil Pressure Control Solenoid Valve ON with a scan tool.
  • Verify the scan tool Engine Oil Pressure Control Solenoid Valve Control Circuit High Voltage Test Status parameter displays OK.
  • ¤If OK is not displayed

  • Ignition OFF, disconnect the harness connector at the K20 Engine Control Module, ignition ON.
  • Test for less than 1 V between the control circuit and ground.
  • ¤If 1 V or greater, repair the short to voltage on the circuit.

    ¤If less than 1 V, replace the K20 Engine Control Module.

    ¤If OK is not displayed

  • Install a 3 A fused jumper wire between the control circuit terminal 2 and the ignition circuit terminal 1.
  • Verify the scan tool Engine Oil Pressure Control Solenoid Valve Circuit High Voltage Test Status parameter is displaying Malfunction when commanding the Engine Oil Pressure Control Solenoid Valve ON with a scan tool.
  • ¤If Malfunction is not displayed

  • Ignition OFF, disconnect the harness connector at the K20 Engine Control Module.
  • Test for less than 2 ohms in the control circuit end to end.
  • ¤If 2 ohms or greater, repair the open/high resistance in the circuit.

    ¤If less than 2 ohms replace the K20 Engine Control Module.

    ¤If Malfunction is displayed

  • Test or replace the Q44 Engine Oil Pressure Control Solenoid Valve.
  • Component Testing

    Static Test

  • Ignition OFF, disconnect the harness connector at the Q44 Engine Oil Pressure Control Solenoid Valve.
  • Test for 10-30 ohms between the control terminal 2 and the ignition voltage terminal 1.
  • ¤If not between 10.0-30.0 ohms

    Replace the Q44 Engine Oil Pressure Control
    Solenoid Valve.

    ¤If between 10.0-30.0 ohms

  • Test for infinite resistance between each terminal and the Q44 Engine Oil Pressure Control Solenoid Valve housing.
  • ¤If not between 10.0-30.0 ohms

    Replace the Q44 Engine Oil Pressure Control Solenoid
    Valve.

    ¤If between 10.0-30.0 ohms

  • All OK.
  • Repair Instructions

    Perform the Diagnostic Repair Verification See: Verification Tests after completing the repair.

  • Oil Pump Flow Control Valve Replacement See: Engine, Cooling and Exhaust\Engine\Engine Oil Control Valve\Service and Repair\Oil Pump Flow Control Valve Replacement Engine Oil Pressure Control Solenoid Valve Replacement
  • Control Module References See: Testing and Inspection\Programming and Relearning\Control Module References for engine control module replacement, programming, and setup
