P0130

Wiring Diagram:

DTC P0130 determines if the oxygen sensor (O2S) is fluctuating properly. Under certain operating conditions, the O2S voltage should consistently fluctuate over 600 mv and under 300 mv. DTC P0134 - O2S Insufficient Activity tests that the O2S voltage is fluctuating outside the inactive range (391-491 mv), however, the 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, the O2S voltage fluctuates outside the larger range. If under certain conditions, the O2S voltage is not fluctuating over 600 mv and under 300 mv, DTC P0130 will set.

DTC PARAMETERS
DTC P0130 will set if the O2S voltage is not fluctuating outside 300-600 mv for 50 seconds when:
^ TP greater than 6%.
^ Engine is at operating temperature.
^ Engine is in closed loop.

DIAGNOSTIC AIDS
Cause: Faulty or contaminated sensor.
Correction: Replace the front oxygen sensor (O2S).
