The term NO x represents several forms of nitrogen oxides such as NO (nitric oxide), NO 2 (nitrogen dioxide) and N 2 O (nitrous oxide, also known as laughing gas).In a gasoline engine, NO is the most common form of NO x at around 93%, while NO 2 is around 5% and the rest is N 2 O.
Honda is recalling more than three quarters of a million vehicles in the U.S. because a faulty sensor may cause the front passenger air bags to inflate when they're not supposed to in a crash.
A check engine light or malfunction indicator lamp (MIL), is a tell-tale that a computerized engine-management system uses to indicate a malfunction or problem with the vehicle ranging from minor (such as a loose gas cap) to serious (worn spark plugs, engine problems or a faulty oil valve, etc.).
The BMW was "at or below the standard ... with exception of rural-up/downhill driving conditions". [96] But the researchers found that under real-world driving conditions the Jetta exceeded US emissions limits "by a factor of 15 to 35" while the Passat exceeded the limit "by a factor of 5 to 20".

EGT Sensor on "Ambulance Package" Chassis Cab Trucks. Certain 2011 and 2012 F-350 through F-550 trucks with the "Ambulance Package" had faulty EGT sensors. Failures could cause vehicle shutdown while driving or difficulty restarting. Ford issued a recall (recall 13S10) to replace the sensors, primarily in emergency vehicles.
EGR valve the top of box on top of the inlet manifold of a Saab H engine in a 1987 Saab 90. In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide (NO x) emissions reduction technique used in petrol/gasoline, diesel engines and some hydrogen engines. [1]
A control loop is permanently monitoring the signal of one or more knock sensors (commonly piezoelectric sensor which are able to translate vibrations into an electric signal). If the characteristic pressure peak of a knocking combustion is detected the ignition timing is retarded by steps of a few degrees.
It can be used to detect reckless driving in real time based on the sensor data provided through the OBD port. [49] This detection is done by adding a complex events processor (CEP) to the backend and on the client's interface. OBD II is also monitored to block mobile phones when driving and to record trip data for insurance purposes. [50]
