DTC DETECTION LOGIC
To judge the malfunction, the diagnosis checks that the A/F signal computed by ECM from the A/F sensor 1 signal is not inordinately high.
DTC No. | CONSULT screen terms (Trouble diagnosis content) | DTC detecting condition | Possible cause |
P0132 | A/F SENSOR1 (B1) (O2 sensor circuit high voltage bank 1 sensor 1) | The A/F signal computed by ECM from the A/F sensor 1 signal is constantly approx. 5 V. |
