Ammonia Sensors GG-NH3-2% HIGH-RANGE AMMONIA SENSOR

Since low-range sensors can’t detect high enough and high-range sensors can’t detect accurately at low levels, the use of the GG-NH3-2% sensor in conjunction with low-range GG-NH3 sensors ensures a second-stage line of defense in the event of a serious ammonia leak. Intended for electrical shutdown, the GG-NH3-2% provides

What will cause an oxygen sensor to go bad

2009-04-29· When properly heated, a difference in oxygen between ambient air and what's in the exhaust stream will produce a small voltage. Over time, the sensor can become sluggish or quit working altogether as its exposure to super-hot exhaust simply wears it away. To work, the sensor must be hot. Exhaust gas supplies some of this heat, but modern ...

What Types of Things Could Cause a Crank Sensor to Go Bad ...

A faulty crank sensor can cause your car to "die" or render it unable to start even though the engine may be operating normally. A crank sensor relays information to the vehicle's computer, referencing how fast the engine is running, but more importantly the position of the crankshaft and the cylinder. This sensor is instrumental in controlling ignition and timing of the engine, as well as ...
