Can an oxygen sensor cause the car to fail emissions test?
Yes, along with dozens of other things.
Will the knock sensor cause A car to fail a smog test?
Yes. Any faulty emissions control sensor, including knock sensors, will result in an automatic fail of any emissions control test, period. It doesn't even matter if your vehicle's actual exhaust emissions are within acceptable limits. In most cases, once it is determined that a sensor is bad, the test is ended immediately, and considered failed.
I have 96 Saturn sl2 What happen when oxygen sensor is broke?
The first indication of a failed oxygen (O2) sensor are warning lights to check or service the engine. A check engine light or saved problem code such as O2 problem can cause the vehicle to fail inspections. O2 sensors are an emissions component. The vehicle may also lose performance, fuel economy, and may damage other components.
O2 sensor can cause high Nox?
Nox is The abbreviation of Oxide(s) of Nitrogen. These are only produced at high burn temperature's. In a modern engine excess Nox emissions can be caused by a lean fuel mixture caused by a failed O2 sensor(s) Or A failed or pluged EGR valve
Your mechanic said that your engine light is on because of the catalytic conv is there a sensor on it that would throw the code?
A failed oxygen sensor could possibly cause a catalytic converter fault code.
Will bad oxygen sensors cause me to fail the emissions test?
Problems with the oxygen sensors are quite likely to cause emissions test problems. The car computer cannot properly adjust the air/fuel mixture to regulate the emissions.
What mechanical problems can cause a loss of gas mileage?
Dirty air filter faulty oxygen sensor fouled or old sparkplugs malfunctioning injectors plugged ecv (emissions control valve)
What is cause of check emissions light on Renault scenic?
There are multiple reasons the check emissions light may come on in a Renault Scenic. It could be something as simple as the gas cap not being on properly, but it may also be something more expensive like the oxygen sensor.
Will an oxygen sensor make a car lose power?
A malfunctioning oxygen sensor can cause the engine to be low on power.
What does a faulty oxygen sensor cause on a 1997 Chrysler?
Check engine light, low power, increased emissions, poor fuel economy,Check engine light, low power, increased emissions, poor fuel economy,
Does your o2 sensors control your idle?
Not directly. The oxygen sensor measures oxygen levels in the exhaust. The computer uses that to calculate fuel and spark timing. If an oxygen sensor is malfunctioning, it could cause idle problems.Not directly. The oxygen sensor measures oxygen levels in the exhaust. The computer uses that to calculate fuel and spark timing.

Can a crankshaft sensor cause a failure to pass smog test?
Probably not as the emissions test (Smog test) is carried out by inserting a sensor into the exhaust pipe.
