What causes a low voltage on an O2 sensor?
This causes the air/fuel mixture to go Lean and makes the O2 sensor produce and report a voltage below 0.500 Volts. Depending on how Lean the air/fuel mixture is, the O2 sensor’s voltage can go as low as 0.050 to 0.100 Volts.
Where are the O2 sensors located on a 2004 Jeep Grand?
Re: Where are the o2 sensors located on a 2004 jeep grand… Grand Cherokee oxygen sensor locations for 4.0 and 4.7 engines… An O2 sensor is a galvanic battery that provides the PCM with a voltage signal (0-1 volt) inversely proportional to the amount of oxygen in the exhaust.
Why is the O2 sensor on my Wrangler bad?
Your Wrangler’s oxygen sensors are responsible for helping to keep your engine running at optimal efficiency. The engine management computer uses the data from all of the O2 sensors to keep the air/fuel mixture optimized. A bad oxygen sensor can affect the mixture greatly.
What is the voltage of the oxygen sensor?
If it injects too much, the air/fuel mixture is considered Rich and when this happens, the oxygen sensor reacts by producing a voltage above 0.500 Volts. Depending on how Rich the air/fuel mixture, this voltage can go as high as 0.900 to 1.0 Volt.
This causes the air/fuel mixture to go Lean and makes the O2 sensor produce and report a voltage below 0.500 Volts. Depending on how Lean the air/fuel mixture is, the O2 sensor’s voltage can go as low as 0.050 to 0.100 Volts.

Where are the O2 sensors located on the Jeep Wrangler?
O2 sensors basically sniffs the exhaust and outputs voltage between 0 and 1 volt indicating how much oxygen is in the exhaust. The PCM reads the output voltage from the O2 sensor to adjust the rich/lean condition of the fuel mixture. Where are the sensor/s located?
If it injects too much, the air/fuel mixture is considered Rich and when this happens, the oxygen sensor reacts by producing a voltage above 0.500 Volts. Depending on how Rich the air/fuel mixture, this voltage can go as high as 0.900 to 1.0 Volt.
