P0033-TURBOCHARGER SURGE VALVE CONTROL CIRCUIT





For a complete wiring diagram Refer to the Wiring Information

- When Monitored:
With the engine running, battery voltage above 10 volts, and the control circuit active.

- Set Condition:
The PCM detects that the control circuit voltage is not within a specified range based on operating conditions.





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding.Pre-Diagnostic Troubleshooting Procedure

1. DTC IS ACTIVE
1. Ignition on, engine not running.
2. With the scan tool, Clear DTCs in the Powertrain Control Module (PCM).
3. Start the engine and allow it to reach normal operating temperature.

WARNING: When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts or fan. Do not wear loose clothing. Failure to follow these instructions may result in possible serious or fatal injury.

4. With the scan tool, select View DTCs.

Is the status Active for this DTC?

Yes

- Go to 2

No

- Refer to the *CHECKING FOR AN INTERMITTENT DTC Diagnostic Procedure.Checking for an Intermittent DTC

2. (F344) FUSED ASD/MAIN RELAY OUTPUT CIRCUIT OPEN OR HIGH RESISTANCE




1. Turn the ignition off.
2. Disconnect the Surge Solenoid connector.
3. Turn the ignition on.
4. Using a 12 volt test light connected to ground, check the (F344) Fused ASD/Main Relay Output circuit in the Surge Solenoid 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

- Go to 3

No

- Repair the (F344) Fused ASD/Main Relay Output circuit for an open circuit or high resistance.
- Perform the PCM Verification Test.PCM Verification Test

3. (K150) SURGE SOL CONTROL CIRCUIT OPEN OR HIGH RESISTANCE




1. Turn the ignition off.
2. Disconnect the Powertrain Control Module (PCM).

NOTE: When checking circuits at the Powertrain Control Module (PCM), be careful not to damage or distort the connector terminals. Improper measurement technique could result in poor pin to terminal contact.

3. Measure the resistance of the (K150) Surge Sol Control circuit between the Surge Solenoid harness connector and the Powertrain Control Module (PCM) harness connector.

Is the resistance below 5.0 ohms?

Yes

- Go to 4

No

- Repair the (K150) Surge Sol Control circuit for an open circuit or high resistance.
- Perform the PCM Verification Test.PCM Verification Test

4. SURGE SOLENOID ACTUATION




1. Connect the Powertrain Control Module (PCM) connector.
2. Turn the ignition on.
3. With the scan tool, actuate the Surge Solenoid control to the ON (100%) position.
4. Using a 12 volt test light connected to 12 volts, check the (K150) Surge Sol Control circuit in the Surge Solenoid 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

- Go to 5

No

- Go to 6

5. SURGE SOLENOID
1. Turn the ignition off.
2. Inspect the wiring and connectors between the Surge Solenoid and the Powertrain Control Module (PCM).
3. Look for any chafed, pierced, pinched, or partially broken wires.
4. Look for broken, bent, pushed out or corroded terminals. Verify that there is good pin to terminal contact in the related connectors.

Were any problems found?

Yes

- Repair as necessary.
- Perform the PCM Verification Test.PCM Verification Test

No

- Replace the Surge Solenoid.
- Perform the PCM Verification Test.PCM Verification Test

6. POWERTRAIN CONTROL MODULE (PCM)
1. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Surge Solenoid and the Powertrain Control Module (PCM).
2. Look for any chafed, pierced, pinched, or partially broken wires.
3. Look for broken, bent, pushed out or corroded terminals. Verify that there is good pin to terminal contact in the related connectors.
4. Search for any Technical Service Bulletins that may apply.

Were any problems found?

Yes

- Repair as necessary.
- Perform the PCM Verification Test.PCM Verification Test

No

- Replace and program the Powertrain Control Module (PCM).
