Which is the oxygen sensor out of range?
P0151 Upstream Heated Oxygen Sensor (HO2S21) Circuit Out Of Range Low Voltage (Bank 2). P0153 Upstream Heated Oxygen Sensor (HO2S21) Circuit Slow Response (Bank 2). Really bad gas mileage. Won’t pass state mandated emission testing.
How can I change the oxygen sensor on my car?
Locate the oxygen sensor on your vehicle by looking for a part that looks like a spark plug that sticks out from the exhaust pipe. It will have an electrical connection attached to it. Disconnect the electrical connection on the oxygen sensor. Use a flat tip screwdriver to push in the tabs and pull the connection apart.
Can you test the O2 sensor on a GM 4.3L?
Testing the oxygen sensor (commonly referred to as O2 sensors) on your 4.3L, 5.0L, or 5.7L GM vehicle is not that hard to do. Since oxygen sensors are not cheap and sometimes the PCM (Powertrain Control Module = Fuel Injection Computer) accuses them of being bad, when they aren’t, testing them is a good idea and this article will help you.
What are the symptoms of a bad oxygen sensor?
The effects of a bad oxygen sensor can be very subtle since they usually do not cause serious drive-ability problems. Here are the most common symptoms: The check engine light (CEL) will be illuminated on your instrument cluster. P0131 Upstream Heated Oxygen Sensor (HO2S11) Circuit Out Of Range Low Voltage (Bank 1).
What does the oxygen sensor in a car do?
The oxygen sensor in your vehicle measures the amount of oxygen in your exhaust gas in order to determine the amount of air needed for the fuel injectors, which gives you optimal performance and fewer emissions. It measures the air-to-fuel ratio and sends the information to the computer where adjustments are made.
Can a genuine GM oxygen sensor be replaced?
If you need to replace your oxygen sensor, only do it with a genuine OEM GM oxygen sensor. An OEM oxygen sensor will be optimized to meet the needs of your vehicle. It will know the right amount of fuel to air. An OEM oxygen sensor will last as long as the original part.
