DTC detecting condition Trouble area
DTC P0131:
A/F sensor (LF+) terminal voltage is lower than specified range or A/F sensor
output current is lower than specification.
(2 driving cycle detection logic)
DTC P0132:
A/F sensor (LF+) terminal voltage is higher than specified range or A/F sensor
output current is more than specification.
(2 driving cycle detection logic)
DTC P0134:
Impedance of A/F sensor element is higher than specification for more than
160 sec even though A/F sensor heater is turned ON for more than specified
time with engine running. (A/F sensor or sensor circuit open)
(2 driving cycle detection logic)
