Pcm Code P013 - Rear Oxygen Sensor Not Ready: Action
PCM turns on SERVICE ENGINE SOON light and closed loop is disabled. PCM enables canister purge solenoid if Code P017 is set.
NOTE:
Test numbers refer to numbers on diagnostic chart. See POWERTRAIN CHARTS for references to CHART 7.
- Voltage on PCM data parameter PD33 should fluctuate from less than 0.3 volt to greater than 0.6 volt. If voltage remain greater than 0.6 volt, check circuit No. 412 for short to voltage. If voltage remains less than 0.3 volt, check circuit No. 412 for short to ground.
- Measuring voltage using voltmeter will isolate sensor/wiring problem from a PCM problem. If voltage fluctuates at greater than 0.6 volt and less than 0.3 volt, fault is with PCM. If voltage remains less than 0.3 volt, check circuit No. 412 for short to ground or circuit No. 413 for short to voltage. If voltage remains greater than 0.6 volt, check circuit No. 412 for short to voltage. If voltage remains 0.3-0.6 volt, check circuits No. 412 and 413 for an open.
