Code P013, Rear Heated Oxygen Sensor Not Ready: Action
PCM turns on MIL 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. 1670 for short to voltage. If voltage remains less than 0.3 volt, check circuit No. 1670 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. 1670 for short to ground or circuit No. 1671 for short to voltage. If voltage remains greater than 0.6 volt, check circuit No. 1670 for short to voltage. If voltage remains 0.3-0.6 volt, check circuits No. 1670 and 1671 for an open.
