DTC P0130:00 |
A/F sensor circuit problem |
|---|---|
|
DETECTION CONDITION
|
• The PCM monitors the voltage between PCM terminal 2AD and 2AC while the A/F sensor active. If the voltage deviate from specified range, the PCM determines that there is a A/F sensor circuit problem.
Diagnostic support note
• This is an intermittent monitor (A/F sensor, HO2S).
• The MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
• PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
• FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
• The DTC is stored in the PCM memory.
|
|
POSSIBLE CAUSE
|
• A/F sensor connector or terminals malfunction
• PCM connector or terminals malfunction
• A/F sensor malfunction
• PCM malfunction

|
Yes
|
Go to the next step.
|
|
No
|

• Make sure to reconnect all disconnected connectors.
• Clear the DTC from the PCM memory using the M-MDS.
• Perform the Drive Mode 03 (A/F sensor heater, HO2S heater, A/F sensor, HO2S and TWC Repair Verification Drive Mode).
• Is the PENDING CODE for this DTC present?
|
Yes
|
Repeat the inspection from Step 1.
• If the malfunction recurs, replace the PCM.
Go to the next step.
|
|
No
|
Go to the next step.
