Obviously they didn't "forget" to do the emissions test. They tested it and found out how much it would cost to repair the vehicle, so they sold it to you, claiming that they forgot. Talk to someone at the state regulating agency that oversees used care sales. If necessary, take them to small claims court.

How do you know when you need to replace your catalytic converter?
A catalytic converter could need replacing for a couple of reasons. If your municipality require emissions testing a defective converter could be the source of fail emissions problem but the most common reason that a converter is replace is plugging off the exhaust system lowering the performance of the engine. If your car appears to run properly but lacks power a clogged catalytic converter could be the source of the problem. One of the quickest ways to verify this is an intake manifold vacuum check. If the vacuum reading is low and steady this is an indication of a plugged converter.
Where is the catalyst efficiency below threshold bank 1 located is it the converter that is on the driver side it is an Audi a4 3.0 liter quattro?
the trouble code you have received actually means that the oxygen sensor is reading that your catalytic converter (which breaks down harmful emissions ) is no longer operating properly. Either the oxygen sensor is faulty and is giving a incorrect reading,which means you must repalce it, or the catalytic converter is faulty, and must be replaced.
Will the GReddy Ti-C Catback Exhaust System for 06-09 Honda Civic affect my emissions reading?
The GReddy Ti-C Catback Exhaust System will have absolutely no effect on emissions readings because it retains the stock catalytic converter.
What is a normal reading for a bank 1 sensors?
A normal reading for Bank 1 oxygen sensors, typically located before and after the catalytic converter on the side of the engine with cylinder number one, should fluctuate between 0.1 to 0.9 volts in a healthy operating engine. The upstream sensor (pre-catalytic converter) should show rapid changes as the engine's fuel mixture adjusts, while the downstream sensor (post-catalytic converter) should stabilize around 0.5 volts if the catalytic converter is functioning correctly. Consistent readings outside these ranges may indicate issues with the sensors, fuel mixture, or the catalytic converter.
Is the 02 sensor connected to the vent solenoid?
O2 (oxygen) sensors come in pairs. One is placed before the catalytic converter to get an exhaust reading for unused fuel vapors. The other is placed after the converter to measure the same. The on board computer compares the two readings to make sure the converter is working (heating up to burn unused gas vapors for cleaner emissions).
Will a bad catalytic converter burn gas?
Yes, a faulty catalytic converter can cause fuel consumption to raise. Replacing a known bad catalytic converter will help, but keep in mind, the catalytic converter usually does not fail on its own. converters are pretty tough, living their lives running at 2000+ degrese internally. I would check your EGR valve and EGR valve tube for blockage or carbon build up. a faulty or clogged EGR valve will overtime distroy a catalytic converter. second thing to check is your Oxygen Sensors. these sensors are the computers first reading of bad fuel mixture, if they are clogged with carbon, they can distroy your EGR valve, which inturn kills your converter.
What does code p0137 mean on a 2003 hyundai santa fa?
Code P0137 on a 2003 Hyundai Santa Fe indicates a problem with the oxygen sensor circuit, specifically the downstream (post-catalytic converter) oxygen sensor. This code typically means that the sensor is reading a low voltage, which can suggest a malfunctioning sensor, a problem with the wiring or connectors, or issues with the catalytic converter. It’s important to diagnose the problem accurately to ensure proper engine performance and emissions control.
What rear oxygen sensor does?
The rear oxygen sensor looks at the percentage of oxygen in the exhaust after it has passed through the catalytic convertor. The computer compares this with the reading from the front sensor to tell if the catalytic converter is working correctly.
What does a P0420 reading on the check engine light mean on a 1996 ford explorer 6 cylinder?
Bank 1 catalytic converter efficiency failure.
Can you remove catalytic converter from 1997 sidekick?
No, it will cause the after cat oxygen sensor to send an incorrect reading to the computer. Federal law prohibits their removal anyway.
What harm will removing the catalytic converter on 2000 ford expedition will this cause?
1. illegal 2. will cause check engine light to stay on. 3. The engine computer will try to compensate for false oxygen sensor reading due to the missing catalytic converter, This will causes a loss of power, lower fuel economy, and poor driveability.
Where is the oxygen sensor located?
Depending on model as some have one sensor, some have two and some have four of them, I would look just before and just after the catalytic converter. The sensor reads oxygen content and reports back to the Powertrain control module (computer) the one before and the one after have a different reading as the converter changes the content. The PCM evauluates and change the fuel air mixure to correct.
