Code P017, Front Oxygen Sensor Not Ready: Action
PCM turns on MIL. PCM enables canister purge solenoid if Code P013 is also set. Closed loop operation is disabled.
NOTE:
Test numbers refer to numbers on diagnostic chart.
- Voltage on PCM data parameter PD32 should fluctuate from greater than 0.6 volt to less than 0.3 volt. If voltage remains at greater than 0.6 volt, check circuit No. 412 for a short to voltage. If voltage remains at less than 0.3 volt, check circuit No. 412 for a short to ground.
- Measuring voltage using a voltmeter will isolate a sensor/wiring problem from a PCM problem. If voltage fluctuates at greater than 0.6 volt and less than 0.3 volt, PCM is faulty. If voltage remains at less than 0.3 volt, check circuit No. 412 for a short to ground or circuit No. 413 for a 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.
