Code P017, Front Oxygen Sensor Not Ready: Action
PCM turns on MIL and closed loop operation is disabled. PCM enables EVAP canister purge solenoid if Code P013 is also set.
NOTE:
Test numbers refer to numbers on diagnostic chart.
- Voltage on PCM data parameter PD32 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.
