Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE - STANDARD PROCEDURE)



Diagnostic Test

1. DTC IS ACTIVE

Start the engine.
Allow the engine to reach normal operating temperature.

NOTE: Diagnose and repair any system voltage or sensor reference voltage DTCs before continuing with this test.


With the scan tool, select View DTCs.

Is the status Active for this DTC?

Yes


No

2. (K857) 5 VOLT SUPPLY CIRCUIT VOLTAGE



Turn the ignition off.
Disconnect the Manifold Flow Valve connector.
Turn the ignition on.
Measure the voltage of the (K857) 5 Volt Supply circuit in the Manifold Flow Valve harness connector.

Is the voltage between 4.5 and 5.5 volts?

Yes


No

3. (K602) MFV SIGNAL CIRCUIT VOLTAGE



Measure the voltage of the (K602) MFV Signal circuit in the Manifold Flow Valve harness connector.

Is the voltage between 4.5 and 5.5 volts?

Yes


No

4. (K900) SENSOR GROUND CIRCUIT TEST

Turn the ignition off.
Using a 12 volt test light connected to 12 volts, check the (K900) Sensor Ground in the Manifold Flow Valve harness connector.

NOTE: The test light should be illuminated and bright. Compare the brightness to that of a direct connection to the battery.



Is the test light illuminated and bright?

Yes


No

5. (K857) 5 VOLT SUPPLY CIRCUIT SHORTED TO THE (K602) MFV SIGNAL CIRCUIT



Turn the ignition off.
Disconnect the Powertrain Control Module (PCM) connector.
Measure the resistance between the (K857) 5 Volt Supply circuit and the (K602) MFV Signal circuit in the Manifold Flow Valve harness connector.

Is the resistance above 100 ohms?

Yes


No

6. MANIFOLD FLOW VALVE

Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Manifold Flow Valve and the Powertrain Control Module (PCM).
Look for any chafed, pierced, pinched, or partially broken wires.
Look for broken, bent, pushed out or corroded terminals.
Inspect the Manifold Flow Valve for any condition that would result in an incorrect signal, such as damage or contamination.

Were any problems found?

Yes


No

7. (K857) 5 VOLT SUPPLY CIRCUIT SHORTED TO VOLTAGE



Turn the ignition off.
Disconnect the Powertrain Control Module (PCM) connector.
Turn the ignition on.
Measure the voltage of the (K857) 5 Volt Supply circuit in the Manifold Flow Valve harness connector.

Is there any voltage present?

Yes


No

8. (K857) 5 VOLT SUPPLY CIRCUIT SHORTED TO GROUND



Turn the ignition off.
Measure the resistance between ground and the (K857) 5 Volt Supply circuit in the Manifold Flow Valve harness connector.

Is the resistance above 100 ohms?

Yes


No

9. (K857) 5 VOLT SUPPLY CIRCUIT SHORTED TO THE (K900) SENSOR GROUND CIRCUIT



Measure the resistance between the (K857) 5 Volt Supply circuit and the (K900) Sensor Ground circuit in the Manifold Flow Valve harness connector.

Is the resistance above 100 ohms?

Yes


No

10. (K857) 5 VOLT SUPPLY CIRCUIT OPEN OR HIGH RESISTANCE



Measure the resistance of the (K857) 5 Volt Supply circuit between the Manifold Flow Valve harness connector and the Powertrain Control Module (PCM) harness connector.

Is the resistance below 5.0 ohms?

Yes


No

11. (K602) MFV SIGNAL CIRCUIT SHORTED TO VOLTAGE



Turn the ignition off.
Disconnect the Powertrain Control Module (PCM) connector.
Turn the ignition on.
Measure the voltage of the (K602) MFV Signal circuit in the Manifold Flow Valve harness connector.

Is there any voltage present?

Yes


No

12. (K602) MFV SIGNAL CIRCUIT SHORTED TO GROUND



Turn the ignition off.
