Oxygen Sensor Codes - A Complete Guide On Diagnosing ...

Oxygen Sensors, otherwise referred to as O2 Sensors, and their related check engine light codes, can be troublesome at the very best! Today we discuss the design and function of these sensors, and some of the pitfalls encountered during the diagnosis of their related fault codes. It seems as though the check engine light and O2 Sensor codes have always gone hand in hand. I can't even begin to ...

Wideband sensor codes also identifies the location of the sensor, such as sensor 1 or 2, cylinder row 1 or 2. Sensor 1 represents the primary/regulating wideband sensor at the exhaust manifold. Sensor 2 is the secondary/controlling sensor behind the catalytic converter. Sensor 2 are conventional O2 sensors, not wideband sensors. Cylinder row 1 is the bank, that contains cylinder number one in ...

Lambda sensor testing and troubleshooting | HELLA

The lambda sensor displays a rich or lean mixture in the range of λ = 1. The broadband lambda sensor offers the option to measure a precise air ratio in both the lean (λ > 1) and rich (λ 1) ranges. It delivers an exact electrical signal and can therefore control any reference values – for diesel engines, gasoline engines with lean ...

How does an NDIR CO2 Sensor Work? |

An engineering breakthrough occurred in 1993 when SenseAir AB patented a design for small-footprint CO2 sensors. These sensors solved the size problem by using folded optics and metalized molded plastic to reflect the light through a curved shape (referred to as a 'waveguide') that was longer than the footprint of the sensor module. The highly reflective coating ensured that the CO2 molecules inside …

Capacitive Sensor Operation and Optimization | Lion Precision

But capacitive sensors can be effective in measuring presence, density, thickness, and location of non-conductors as well. Non-conductive materials like plastic have a different dielectric constant than air. The dielectric constant determines how a non-conductive material affects capacitance between two conductors. When a non-conductor is inserted between the probe and a stationary reference ...

CO2 Sensor Calibration: What You Need to Know |

The most accurate method of CO2 sensor calibration is to expose it to a known gas (typically 100% nitrogen) in order to duplicate the conditions under which the sensor was originally calibrated at the factory. ISO certification is available on our high-end sensors to verify this process for medical, research or scientific purposes. Nitrogen calibration is also required if CO2 levels between 0-400 ppm will be …
