Customer Concern: Intermittently, the engine is running poorly and is setting a pending trouble code of P0152.
Verify the wiring to the O2 sensors is normal. These sensors will normally switch between 2.5 volts and 3.5 volts when they are working correctly. The sensor ground will have 2.5 volts on it and this is normal for this vehicle. Many brands of replacement sensors do not work. Make sure to use O2 sensors that meet all Original Equipment Manufacturer (OEM) specifications.
