7 1. Ignition “OFF”.
2. With the PCM disconnected, check continuity of the
Bank 2 HO2S 2 high circuit.
3. If the Bank 2 HO2S 2 high circuit measures over 5.0
ohms, repair open or poor connections as
necessary.
Was a Bank 2 HO2S 2 high circuit problem found and
corrected?
— Verify repair Go to Step 8
8 1. Ignition “OFF”.
2. With the PCM disconnected, check continuity of the
Bank 2 HO2S 2 low circuit.
3. If the Bank 2 HO2S 2 low circuit measures over 5
ohms, repair open or poor connections as
necessary.
Was a Bank 2 HO2S 2 low circuit problem found and
corrected?
— Verify repair Go to Step 9
9 1. Ignition “ON”, engine “OFF”.
2. Disconnect Bank 2 HO2S 2 and jumper the HO2S
high and low circuits (PCM side) to ground.
3. Using a Tech 2, monitor Bank 2 HO2S 2 voltage.
Is Bank 2 HO2S 2 voltage in the specified range?
0-10 mV Go to Step 10 Go to Step 11
10 Replace Bank 2 HO2S 2.
