co2 sensor reading out of range

Python Loop: List Index Out of Range - Stack Overflow

IndexError: list index out of range I'm pretty sure it occurs because by the time I get the the last element of a (3), I can't add it to anything because doing so goes outside of the value of it (there is no value after 3 to add). So I need to tell the code to stop at 2 while still referring to 3 for the calculation.

Oxygen Sensor (O2) - What Else Could Cause Rich Or Lean Codes

Jul 10, 2020· The (O2) sensor can last up to 100K miles, but typically you would experience problems sooner than that. Over time, an (O2) sensor may become caked with byproducts of combustion, such as sulfur, lead, fuel additives, oil ash, etc. This contamination causes the sensor to lose its ability to produce voltage and send the right signal.

Carbon Dioxide (CO2) in Blood: MedlinePlus Medical Test

It is a waste product made by your body. Your blood carries carbon dioxide to your lungs. You breathe out carbon dioxide and breathe in oxygen all day, every day, without thinking about it. A CO2 blood test measures the amount of carbon dioxide in your blood. Too much or too little carbon dioxide in the blood can indicate a health problem.

How To Test a Chevy Silverado O2 Sensor - My Pro Street

Feb 10, 2016· Remember you are resting the SENSOR side of the equation, and that you need to turn your multimeter dial to measure resistance Ω. By measuring the internal resistance of your upstream Silverado oxygen sensor, it should return a value between 5 to 16 Ω (Ohms). If the measurements fall outside of this range, your Silverado O2 sensor has died.
