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.
What else can I help you with?
Would someone help with 99 accord that keeps failing smog due to the MIL light The OBD codes that came up were P1164 P1149 P0401. Ive already spent 400 on a knock sensor and cleaning intake manifold?
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
Is there another name for a pollution pump from a 1998 Ford Taurus Could this pump cause the check engine light to come on?
another name is smog pump.this could cause light to come on.
What gases are the sources of smog?
Sulfur dioxide is main source of gas in smog.
In term of their futurewhat did people especially fear about smog?
People feared that smog could lead to severe health problems, including respiratory diseases and long-term complications, impacting their quality of life. Additionally, smog was associated with environmental degradation, which raised concerns about the sustainability of their communities and future generations. The economic implications, such as decreased property values and loss of tourism, also contributed to anxiety about the long-term effects of smog on their livelihoods. Overall, the combination of health, environmental, and economic fears created a pervasive anxiety about the future in smog-affected areas.
What is smog pump pressure psi?
30-40 psi
Will a faulty knock sensor cause 2002 5.3 suburban not to pass smog?
Yes, a faulty knock sensor can lead to a 2002 5.3 Suburban failing a smog test. The knock sensor plays a crucial role in the engine's performance by detecting knocking and adjusting ignition timing accordingly. If it malfunctions, it can cause the engine to run inefficiently, potentially increasing emissions and triggering check engine light codes that may result in failing the smog test. It's advisable to address any issues with the knock sensor before attempting to pass smog.
Your 98 Chevy s10 fails smog test have replaced everything but egr valve and oxygen sensor what else can you do?
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.
Will a bad egr cause smog test fail?
yes it suppose to circulate the smoke if clogged smog test will fail
When should the oxygen sensor be changed on a Grand Am?
Every 60,000 miles, though some can last longer before failing enough to cause you to fail smog.
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.
Will a bad catalytic converter cause you to fail the emissions portion of the smog test?
Yes!
What can cause a 1999 Saturn SC2 to fail the smog test after the battery was replaced?
Have it scanned to determine problem
Will a vehicle pass smog if the o2 sensor is out?
No, it will not pass the smog test with a defective or removed O2 sensor.
How do you test a 1999 daewoo nubira oxygen sensor when the car goes for the smog test it says obd2 fail?
obd2 means on board diagnostics failed not o2 sensor, 1st have to figure out why obd2 failed.
What can make a car not pass a smog check?
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
My 97 ram 1500 reads error code 441 evaporative canister will this cause it to fail the smog test?
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.
What happens if you disconnect the smog sensor on a 2001 galant?
Disconnecting the smog sensor on a 2001 Mitsubishi Galant can trigger the check engine light and cause the vehicle to fail emissions tests. The engine control unit (ECU) may interpret the disconnection as a fault, potentially leading to reduced engine performance or efficiency. Additionally, this action could result in increased emissions and may violate local environmental regulations. It's advisable to address any issues with the sensor rather than disconnecting it.
