FUSED BATTERY VOLTAGE OUTPUT CIRCUIT

AIR INJECTION PUMP RELAY

AIR INJECTION PUMP GROUND CIRCUIT

AIR INJECTION PUMP MOTOR

AIR INJECTION PASSAGES

O2 SENSOR

DIAGNOSTIC PROCEDURE - P0410-AIR INJECTION O2 SENSOR MONITOR

TEST ACTION
1
NOTE: Before performing the following test, always check the Air Pump Assembly in-line connectors. Ensure that there is no terminal damage, corrosion or backed out terminals. Verify that there is good wire to terminal connection in the connector.
Ignition on, engine not running.With the DRBIII®, read DTCs and record the related Freeze Frame data.Is the Good Trip displayed and equal to zero?
  1. Yes --> Go To 2
  2. No --> Refer to the INTERMITTENT CONDITION  symptom in the Driveability category.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .
2 Visually and physically inspect the following components for any conditions that would compromise the air flow.
Inlet Filter - cracks/holes or damage
Inlet Hose - disconnected hose, holes or incorrect installation
Air Injection Pump - cracks/holes or damage to the housing.
Air Injection Pump (Nylon) Tube - disconnected, damage, incorrect routing and holes/cracks.
Exhaust one-way check valve - Improper installation, missing gasket, damage or holes.
Were any of the above conditions found?
  1. Yes --> Repair or replace as necessary.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .

  2. No --> Go To 3
3
WARNING: Before performing this test, to avoid personal injury allow the exhaust manifold and related components to cool down to a safe temperature.
Turn the ignition on.Remove Exhaust one-way valve from the exhaust manifold.Using the DRBIII®, actuate the Air Injection Pump Relay.
NOTE: When the Air Injection Pump is actuated, forced air should come out of the opening of the Exhaust one-way valve.
Does forced air come out of the Exhaust one-way valve?
  1. Yes --> Go To 4
  2. No --> Go To 5
4
WARNING: Before performing this test, to avoid personal injury allow the exhaust manifold and related components to cool down to a safe temperature.
NOTE: The exhaust system must be free of leaks in order for this test to work properly.
Turn the ignition off.Remove the Exhaust one-way valve.Remove the O2 1/1 sensor.Plug the exhaust at the tailpipe.Using the Miller Tool #8404 EELD, inject smoke into the Exhaust one-way valve tube attached to the exhaust manifold.
NOTE: The exhaust system will need to fill with smoke before a concentrated smoke will escape from the O2 sensor exhaust manifold hole.
While injecting smoke into the exhaust manifold, monitor the O2 sensor exhaust manifold hole for a minimum of 2 minutes.Does a consistent concentration of smoke escape from the O2 sensor exhaust manifold hole?
  1. Yes --> Replace the O2 1/1 Sensor.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .

  2. No --> Clean or repair the cylinder head air passages and/or air distribution chamber.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .
5
WARNING: Before performing this test, to avoid personal injury allow the exhaust manifold and related components to cool down to a safe temperature.
Turn the ignition off.Disconnect the Air Injection Tube from the Exhaust one-way valve.Turn the ignition on.Using the DRBIII®, actuate the Air Injection Pump Relay.
NOTE: When the Air Injection Pump is actuated, forced air should come out of the opening of the Air Injection Pump Tube.
Does forced air come out of the Air Injection Pump Tube.
  1. Yes --> Replace the Exhaust one-way valve.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .

  2. No --> Go To 6
6 Turn the ignition off.
Disconnect the Air Injection Pump Motor harness connector.
Turn the ignition on.
Using the DRBIII, actuate the Air Injection Pump Relay.
Using a 12-volt test light connected to ground, probe the Air Injection Pump Relay Output circuit in the Air Injection Pump Motor harness connector.
Does the test light illuminate brightly?
  1. Yes --> Go To 7
  2. No --> Go To 8
7 Turn the ignition off.
Disconnect the Air Injection Pump Motor harness connector.
Using a 12-volt test light connected to battery voltage, probe the Air Injection Pump Motor ground circuit.
Does the test light illuminate brightly?
  1. Yes --> Replace the Air Injection Pump Motor.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .

  2. No --> Repair the open in the Air Injection Pump Ground circuit.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .
8 Turn the ignition off.
Disconnect the Air Injection Pump Relay harness connector.
Turn the ignition on.
Using a 12-volt test light connected to ground, probe the Fused Battery Output circuit in the Air injection Pump Relay harness connector.
Does the test light illuminate brightly?
  1. Yes --> Check the Air Injection Pump relay Output circuit for an open. If OK, replace the Air Injection Pump Relay.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .

  2. No --> Repair the open in the Fused Battery Voltage Output circuit.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .
