Step Action Value(s) Yes No 1 Was the “On-Board Diagnostic (OBD) System Check” — Go to Step 2 Go to OBD System Check 2 1. Install the Tech 2. under “Conditions for Setting the DTC” included in 4. Using a Tech 2, monitor Bank 1 HO2S 1 voltage. Does the Bank 1 HO2S 1 voltage remain above the 952 mV (500 mV in deceleration fuel cutoff mode) Go to Step 4 Go to Step 3 3 1. Ignition “ON,” review and record Tech 2 Failure Records data. 2. Operate the vehicle within Failure Records conditions as noted. 3. Using a Tech 2, monitor “DTC” info for DTC P0132 until the DTC P0132 test runs. 4. Note the test result. Does the Tech 2 indicate DTC P0132 failed this — Go to Step 4 Refer to Diagnostic Aids 4 1. Ignition “OFF.” use a DVM to measure voltages at the high and low Are the voltages in the specified range? 3-4 V Go to Step 5 Go to Step 6 5 Repair short to voltage in signal circuit. Is the action complete? — Verify repair — 6 1. Ignition “ON,” engine“OFF.” both the HO2S high and low signal circuits (PCM 3. Using a Tech 2, monitor Bank 1 HO2S 1 voltage. Is Bank 1 HO2S 1 voltage below the specified value? 10 mV Go to Step 7 Go to Step 8 7 1. Disconnect the jumpers to ground from Bank 1 HO2S 1 PCM-side connector. 2. With the HO2S 1 connector disconnected, monitor Bank 1 HO2S 1 voltage. Is Bank 1 HO2S 1 voltage between the specified 425-475 mV Refer to Diagnostic Aids Go to Step 8 8 Replace the PCM. Is the action complete? — Verify repair — |
