Troubleshooting Oxygen Sensors Walker Products

Common O2 Failure Causes. Oxygen sensor failure can often be traced to one of three common factors: Age and high mileage, an internal contaminant (poisoning) or an electrical issue. One or two wire unheated oxygen sensors should be inspected or replaced every 30,000 miles. These sensors must rely solely on hot exhaust gas to reach their operating temperature, and are designed to let a large ...

JP2016166546A Device for detecting failure of nh3 sensor ...

The sensor generates an electromotive force MAINEMF corresponding to NHand HO between the NHdetection electrode and the reference electrode. A method for detecting failure of the NHsensor comprises an HO amount change step (S3) of changing an amount of the HO in the exhaust pipe, and failure detection steps (S4 to S9) of acquiring a change of the electromotive force MAINEMF …

Cummins ISB fault 3582, NH3 sensor likely? : DieselTechs

Vast majority of those 3 bung cats have come in as failed in my experience. You have an updated cat, updated wiring harness for the SCR sensors that deletes the connector for the NH3 and an updated calibration so the ECM does not search for the NH3 sensor (will need a fleet cal and would have to be done at a dealer unless you got Insight pro and a quickserve log on).

Why TPMS Sensors Fail Tomorrows Technician

· Why Sensors Fail. The No. 1 reason sensors fail is physical damage. Sensors operate in a harsh environment of extreme temperatures and vibration. These forces can damage transmission coils and pressure and temperature sensors. Another reason sensors fail is due to damage during removal and installation. One false move with a bead breaker or tire iron can break the sensor at the stem. …

Why does a sensor fails calibration with reactive gas such ...

Before calibration, stabilize the sensors for at least 30 minutes. Perform a bump test every 30 days. Perform the zero calibration procedure before the span calibration procedure. Due to the nature of the gas, the reading may continue to rise even after exposure to the gas for 3 to 5 minutes. For consistency, use a set time for the calibration (, 4 minutes). Use this time for all subsequent units.
