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.
P0401 EGR Insufficient Flow Detected P1149 Primary HO2S (Sensor 1) Circuit Range/Performance Problem P1164 61 Primary HO2S (No. 1) Circuit Range/Performance The 0401 = bad EGR valve The 1149 = bad O2 sensor, up front The 1164 = bad O2 sensor, up front
another name is smog pump.this could cause light to come on.
Sulfur dioxide is main source of gas in smog.
30-40 psi
That wet, dirty haze is called smog. It comes from combining the words smoke and fog.
A faulty EGR valve can cause a 98 Chevy to fail a smog test. The oxygen sensors should also be tested as they can also cause a 98 Chevy to fail a smog test.
yes it suppose to circulate the smoke if clogged smog test will fail
Every 60,000 miles, though some can last longer before failing enough to cause you to fail smog.
Probably not as the emissions test (Smog test) is carried out by inserting a sensor into the exhaust pipe.
Yes!
Have it scanned to determine problem
No, it will not pass the smog test with a defective or removed O2 sensor.
obd2 means on board diagnostics failed not o2 sensor, 1st have to figure out why obd2 failed.
The answer to this question is fairly complex. We recommend you visit the link below to find out how to pass the smog check and what might cause your vehicle to fail... http://www.smogtips.com/passing_inspection.cfm
It depends on where you live. If you live in a state that requires smog tests, yes, it will cause the vehicle to fail. The test includes verification of the status of the emissions diagnostic codes. In other words, if your car throws a code it won't pass.
If the vehicle has excessive miles it may be burning oil, If you are sure it is in OK condition to pass the test, Try this, drive the vehicle at highway speed for atleast 10 miles, this will get the emissions system up to full operating condition, and make it reduce smog at its max.
the burning of fossil fuels can cause smog and acid rain
