What else can I help you with?
Your 95 prizm failed the emissions the nox reads too high what do you need to replace you cannot find a egr valve on this car it is a 1.6 liter with a 5 speed?
have it scanned and have them ck your oxygen sensor
What is the purpose of a catalytic converter?
To lower the amount of harmful emissions in the exhaust. It converts HC, CO and NOx into H20, CO2, and N2.
What does low nox in water heaters mean?
"Low NOx" in water heaters refers to models that produce lower levels of nitrogen oxide (NOx) emissions during operation. This helps reduce environmental impact and improve air quality by lowering the release of harmful pollutants into the atmosphere.
How do you reduce NOX to pass smog test?
To reduce NOx emissions and pass a smog test, ensure your vehicle's engine is properly tuned, including regular maintenance like replacing spark plugs and air filters. Use high-quality fuel with additives designed to lower NOx emissions. Additionally, check and repair any issues with the exhaust gas recirculation (EGR) system and catalytic converter, as these components play a crucial role in reducing NOx. Lastly, consider using a NOx-reducing catalytic converter if applicable to your vehicle.
Where is the nox sensor?
A NOX sensor is a nitrogen oxide sensor. It is used in a car's exhaust system to check emissions for nitrogen oxide.
What could cause the nox to be to high on a 1999 dodge durango?
Bad EGR, Exhaust Gas Recirculation valve. That is what reduces NoX emissions
Which emissions control system is designed to reduce NOX emissions?
Selective catalytic reduction (SCR) systems are designed to reduce NOx emissions by converting nitrogen oxides into nitrogen, water, and carbon dioxide using a catalyst and a reducing agent such as urea.
How does an EGR valve work?
an egr valve opens to put inert gases in the combustion chamber to lower the temperature. this is done to reduce NOx emissions that are produced at high temperatures.
What is def fluid for?
DEF (diesel exhaust fluid) is used as a consumable in SCR (selective catalytic reduction) in order to lower NOx concentration in the diesel exhaust emissions from diesel engines.
Why does your 1989 Jeep Cherokee fail the nox part on emissions?
If there are no other problems and the vehicle is failing the NOX emissions test, it's probably running too lean. Check the EGR valve, fuel pressure and the Oxygen sensor.
What is the purpose of an EGR valve for a 1993 Ford Probe?
EGR stands for Exhaust Gas Recirculation. It is an emissions control that recylces exhaust gas through the engine to clean out any left over fuel, and to cool the combustion chambers to help lower Nox emissions. Nox is best known as "smog". It is illegal to disable or modify any emissions control on your car. EGR problems generally cause rough idle and sometimes, hard starting.
If your 1995 Geo Prism has failed emissions tests twice should you replace the oxygen sensor or catalytic converter?
Depends on what failed on the emission test. HC? CO? NOx? Combination of these? Check to make sure all the vacuum lines are okay. No cracks or anything.
