Not likely because: Code p0420 refers to a problem with your catalytic converter. The engine computer is able to test that converter by using an oxygen sensor before and after the converter. The computer can only test the converter under very specific driving conditions. If the computer determines that it is a good time to test the catalytic converter it will run the test. It compares the oxygen sensor readings in front of the converter to the readings behind the converter to see if the catalytic converter is functioning properly. If it is not functioning properly it will trigger a p0420. Sometimes if a catalytic converter is on the virge of failing it may fail one test and pass the next. This will cause your check engine light to come off and on every once in a while when the test is performed.
one in each side of the exhaust crossover pipe and one behind the catalytic converter
No your car will infact run better (more power), exhaust gasses are able to flow much more freely without a Cat. The downside you will shorten the life of everyone who drives behind you as a Catalytic Converter Converts deady gases to less harmful gases. Highly Illeagal to remove these from you car. Fines in Australia are something in the order of $10,000.
They are screwed into the exaust system at various points. Some people say that there are 4 oxygen sensors, but technically, that is not correct. Only the front 2 are considered oxygen sensors. They are screwed into the exaust pipe, one on each bank, after the exaust manifold, but before the catalytic converter. Sometimes they are screwed directly into the exaust manfold itself. The other 2 are actually called catalyst moniters. They are oxygen sensors, but they serve a different purpose. They moniter the activities of the catalytic converters, thus the name, catalyst moniters. They are screwed into the exaust one on each bank,after, or downstream, of the catalytic converters. A 7/8ths inch wrench is the size needed to turn the O2 sensors. They just unscrew out normally. The connectors on the front O2's will be a challenge. They are way up behind the engine in a really stupid place to get access and unplug/plug in.
The catalytic converter is in the exhaust pipe directly behind the engine.The catalytic converter is in the exhaust pipe directly behind the engine.
The catalytic converter is behind the engine.
In the exhaust pipe before the catalytic converter, which is right behind the engine
i have a 2002 and if you get under the van and follow the muffler from back to the motor you will find it. It should be in front or behind the catalytic converter. There are two, one in front and one behind the catalytic converter.
The Catalytic converter is located underneath the vehicle right behind the upstream oxygen sensor
There are two. One before and one after the catalytic converter behind the engine.
Right behind the catalytic converter.
The catalytic converter in directly behind the engine. ( might need to use a flashlight ) It is bolted right to the exhaust manifold. The catalytic converter in directly behind the engine. ( might need to use a flashlight ) It is bolted right to the exhaust manifold.
On the exhaust line just behind the area where the 2 manifolds become one but before the catalytic converter. Should have a shroud around it.
There is an upstream and downstream o2 sensor. The upstream is loctaed in the exhaust manifold before the catalytic converter. The downstream is located behind the catlytic converter.
Post is the O2 sensor located behind the converter and Pre is the sensor located in front of the converter. Sometimes also referred to as upstream and downstream.
Immediately behind the engine.
