No.
Loud exhaust noise from the front end is usually caused by one of several problems. The exhaust manifold gasket could be blown, the doughnut gasket could be bad, or there could be a crack in the exhaust itself.
OBD II P0420, Catalyst System Efficiency Below Threshold. In some cases, there may be some performance problems noticed by the driver such as a lack of power from a restricted and/or damaged Catalytic Converter.Common Problems That Trigger the P0420 CodeInefficient Catalytic Converter(s)Defective Front or Rear Oxygen Sensor(s)Misfiring enginesCommon MisdiagnosesOxygen Sensors good-day ! hope this helps !
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.
A number of possible reasons. There could be damage to your tire rims. Your tires could require balancing. Why would you check the exhaust system if the vibration is coming from the front?
In the exhaust pipe at the front of the catalytic converter.In the exhaust pipe at the front of the catalytic converter.
That is the O2 sensor in the exhaust closest to the engine.
yes. bottom of grip. front part of trigger guard and on frame in front of trigger guard...........
front trigger fires right barrel. back trigger fires left. boone
P0420 usually points to a failed catalytic converter, if the exhaust system is intact, that is. Exhaust leaks in front of a catalytic converter can affect the O2 readings and at times throw a false code. P0141 indicates only the heater circuit of the o2 sensor has a problem. Usually it's the element in the sensor, and replacing the sensor would fix that, but it doesn't rule out a harness issue or a short in the wiring
Could be overheated coolant or just leaked oil burning off your exhaust headers
