[QUOTE="hotcobra03, post: 13092084, member: 53096"] i would swap rear o2 side to side and see if code follows.. The HO2S Sensor Signals are monitored for an over voltage fault. The code is set when HO2S signal voltage is 1.5 volts or greater. HO2S Signal Circuit shorted to Heater Power inside of HO2S sensor. HO2S Signal Circuit shorted to VPWR or VREF in harness. PCM failure. An HO2S PID switching across 0.45 volt from 0.2 to 0.9 volts indicates a normal switching HO2S. HO2S PID voltage of 1.5 volts or greater indicates a short to power. [/QUOTE]
