Potential failure modes:
• Low fuel pressure (Lean mixture)
• Malfunctioning sensor
• External water on sensor
• Sensor wire shorted to ground
Diagnostic Mask:
• The MIL will be illuminated if these faults are present for 2 consecutive trips.

Monitor:
• Continuous.
Disable Criteria:
• None
Enable Criteria:
• Engine running
Malfunction Criteria:
• Sensor voltage > 1200V for more than 1.5 seconds consecutively for a specified number of times.
Potential failure modes:

• Leaking or shorted injector
• Purge valve fault
• Oxygen sensor contamination
• Engine oil contamination
• Sensor wire shorted to heater voltage
Diagnostic Mask:
• The MIL will be illuminated if these faults are present for 2 consecutive trips.
