Pinpoint Test G : Oil Pressure Control Solenoid Faults

WARNING: This page is about a different car, the 2018 Ford EcoSport. However, it is still accessible from the selected car via links, so may be relevant.

Refer to ELECTRONIC ENGINE CONTROLS - 1.0L for schematic and connector information.

Normal Operation and Fault Conditions

REFER to: Engine - Overview .

The engine oil pressure control solenoid is also know as the variable oil pump.

DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Condition
PCM P06DA:00	Engine Oil Pressure Control Circuit/Open: No Sub Type Information	Sets when the PCM detects an open on the engine oil pressure control solenoid valve circuit.
PCM P06DB:00	Engine Oil Pressure Control Circuit Low: No Sub Type Information	Sets when the PCM detects a short to ground on the engine oil pressure control solenoid valve circuit.
PCM P06DC:00	Engine Oil Pressure Control Circuit High: No Sub Type Information	Sets when the PCM detects a short to voltage on the engine oil pressure control solenoid valve circuit.

G1 CHECK THE ENGINE OIL PRESSURE CONTROL SOLENOID VALVE SUPPLY VOLTAGE

Ignition OFF.

Disconnect Engine oil pressure control solenoid valve C1744.

Ignition ON.

Measure:

Positive Lead	Measurement / Action	Negative Lead
C1744-1	Courtesy of FORD MOTOR COMPANY	Ground

Is the voltage greater than 11 volts?

Yes

GO to G2

No	VERIFY BJB fuse F22 (10A) is OK. If OK, REPAIR the open circuit. If not OK, REFER to the OEM ELECTRICAL WIRING DIAGRAM INTRODUCTION to identify the possible causes of the circuit short.

G2 CHECK THE ENGINE OIL PRESSURE CONTROL SOLENOID VALVE CIRCUIT FOR A SHORT TO VOLTAGE

Ignition OFF.

Disconnect PCM C1232B.

Ignition ON.

Measure:

Positive Lead	Measurement / Action	Negative Lead
C1744-1	Courtesy of FORD MOTOR COMPANY	Ground

Is any voltage present?

Yes	REPAIR the circuit.

GO to G3

G3 CHECK THE ENGINE OIL PRESSURE CONTROL SOLENOID VALVE CIRCUIT FOR AN OPEN

Ignition OFF.

Measure:

Positive Lead	Measurement / Action	Negative Lead
C1232-78	Courtesy of FORD MOTOR COMPANY	C1744-1

Is the resistance less than 3 ohms?

Yes

GO to G4

No	REPAIR the circuit.

G4 CHECK THE ENGINE OIL PRESSURE CONTROL SOLENOID VALVE CIRCUIT FOR A SHORT TO GROUND

Measure:

Positive Lead	Measurement / Action	Negative Lead
C1744-1	Courtesy of FORD MOTOR COMPANY	Ground

Is the resistance greater than 10, 000 ohms?

Yes

GO to G5

No	REPAIR the circuit.

G5 CHECK THE ENGINE OIL PRESSURE CONTROL SOLENOID VALVE OPERATION
- Connect PCM C1232B.
- Connect Engine oil pressure control solenoid valve C1744.
- Connect an EOP gauge to the oil pressure sender oil galley port. For more information, REFER to: Engine .
  Oil Pressure Test .
- Start the engine.
- NOTE: The PCM PID EOPDC_CMD may or may not be available in the diagnostic scan tool.
  
  If the active command PCMPID EOPDC_CMD is available in the diagnostic scan tool, enable the engine oil pressure control solenoid valve using the PCM PID EOPDC_CMD.
- If the active command PCM PID EOPDC_CMD is not available in the diagnostic scan tool, with the engine running, wait for approximately 20 to 30 seconds, the PCM commands the pump state transition from high pressure mode to low pressure mode.
- A pressure drop of
  8 psi or greater is anticipated. If the engine coolant temperature is less than 100 deg.F (38 deg.C), a pressure drop of
  
  15 psi or greater is anticipated.
Is the expected engine oil pressure drop present?

Yes GO to G6

No GO to G7

G6 VERIFY ENGINE OIL PRESSURE CONTROL SOLENOID VALVE CONNECTION AND WIRING
- Ignition OFF.
- Disconnect Engine oil pressure control solenoid valve C1744.
- Inspect connectors and wiring:
  - corrosion (install new connector or terminals - clean module pins)
  - damaged or bent pins - install new terminals/pins
  - pushed-out pins - install new pins as necessary
Is any damage to the circuit or connector present?

Yes REPAIR the circuit or connector as needed.

No The system is operating correctly at this time. The intermittent concern may have been caused by a loose connection.

G7 CHECK THE ENGINE OIL PRESSURE CONTROL SOLENOID VALVE

Ignition OFF.

Install a new engine oil pressure control solenoid valve. REFER to: Oil Pressure Control Solenoid .

Using a diagnostic scan tool, clear the PCM Diagnostic Trouble Codes (DTCs).

Start the engine.

NOTE: The PCM PID EOPDC_CMD may or may not be available in the diagnostic scan tool.

If the active command PCM PID EOPDC_CMD is available in the diagnostic scan tool, enable the engine oil pressure control solenoid valve using the PCMPID EOPDC_CMD.

If the active command PCM PID EOPDC_CMD is not available in the diagnostic scan tool, with the engine running, wait for approximately 20 to 30 seconds, the PCM commands the pump state transition from high pressure mode to low pressure mode.

A pressure drop of
8 psi or greater is anticipated. If the engine coolant temperature is less than 100 deg.F (38 deg.C), a pressure drop of

15 psi or greater is anticipated.

Is the expected engine oil pressure drop present?

Yes	The cause of the concern was an inoperative engine oil pressure control solenoid valve. The system is now operating correctly.

GO to G8

G8 CHECK FOR CORRECT PCM (POWERTRAIN CONTROL MODULE) OPERATION

Ignition OFF.

Disconnect and inspect the PCM connectors.

Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary

Reconnect the connectors. Make sure they seat and latch correctly.

Operate the system and determine if the concern is still present.

Is the concern still present?

Yes	CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, Refer to PCM GUIDED ROUTINE TESTING

No	The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
