What can be done about high NOx in smog?
The solution to this problem is called De-Carbonizing. It usually costs around two labor hours at a smog check repair station. It will remove a good amount of carbon out of an engine. This will increase combustion space, lower compression and lower NOx. 5. Engine Overheating – Inadequate engine cooling can will high NOx.
What causes high No ( Nox ) in the air?
What Causes High NO (NOx)? Nitrogen Oxide or NO is created when an engine’s combustion chamber temperature reaches over 2500F. Vehicle manufacturers have designed several systems, which when working properly, lower nitric oxide emissions.
What does passing emissions mean in OBD code?
If another problem crops up that IS emissions related you’d have no way to tell because the light is already on. While most people equate their state’s testing as “passing emissions”, many states in fact are doing both an emissions and SAFETY inspection. If you notice, the lamp is not called an emission failure lamp.
Can a car have an incomplete emission monitor?
– 2000 and newer model year vehicles will need all emission monitors in READY or COMPLETE status, with the exception of the EVAP monitor. An incomplete evaporative monitor will not cause a smog check failure.
Can a car pass the smog test with a pending trouble code?
We say “should” because smog technicians have reported, and for unknown reasons, that they’ve had vehicles fail the smog test with only a pending trouble code (s). This is not the norm and 99.9% of the time a vehicle passes the smog test with a pending OBDII trouble code (s).

How does the I / M240 emissions test work?
For the I/M240 test, vehicles are operated on a dynamometer to simulate on-road driving, and the vehicle’s exhaust emissions are captured and analyzed afterward. As far as the gas cap test is concerned, its simple goal is to determine whether there is a proper gas cap on a vehicle and that it does not leak.
