P0130

Schematic:

DTC P0130 determines if Oxygen Sensor (O2S) is fluctuating properly. Under certain operating conditions, O2S voltage should consistently fluctuate over 600 mv and under 300 mv. DTC P0134 - O2S Insufficient Activity tests that O2S voltage is fluctuating outside inactive range (399-499 mv), however, O2S output is not used for fuel control until it is consistently fluctuating outside a larger range (300-600 mv). DTC P0130 tests that under certain conditions, O2S voltage fluctuates outside the larger range. If under certain conditions, the O2S voltage is not fluctuating over 600 mv and under 300 mv a fail counter will be incremented. If percent of total time in closed loop operation is less than 40%, DTC P0130 will set.

DTC PARAMETERS
DTC P0130 will set if in closed loop less than 40% of total time and the following conditions have been met:
^ TP angle is between 10% and 40%.
^ Engine coolant temperature is greater than 65°C (149°F).
^ Engine speed is between 1200 and 3400 rpm.
^ Engine has been running at least 140 seconds.
^ DTCs P0107, P0108, P0117, P0118, P0122, P0123, P0131, P0132, P0134, P0201, P0202, P0203, P0204, P0300, P0325, P0336, P0440, P0442, P0446, P0502, P0601, P0602, P1441, P1621 or P1640 are not set.

DIAGNOSTIC AIDS

IMPORTANT: If DTC P0134 is also set, diagnose that DTC first, then re-test.

Cause: Faulty or contaminated sensor.

Correction: Replace the front Oxygen Sensor (O2S).
