Catalytic Converter Life Expectancy
When working correctly, a catalytic converter cleans up the pollution that stems from your vehicles exhaust. The life expectancy of this part is well above 90,000 miles. However, because some issues can affect this estimate, its wise to test the converter for problems that could shorten its life.
Map Sensor
One way to test the efficiency of a catalytic converter is by disconnecting its MAP sensor. Doing this is supposed to make the converters temperature go up, which indicates no trouble. If the temperature remains the same, the catalyst has likely gone bad. It should also be kept in mind that an error code will occur once the MAP sensor is disconnected.
Plug Wire
By undoing and grounding a plug wire, you can create an overflow of hydrocarbons within the vehicles exhaust pipe. If the temperature goes up drastically, the converter is fine. This test should should not be run for more than two minutes because of the risk that it could damage the converter.
Exhaust Analyzer
An exhaust analyzer can also be used to check the performance of a catalytic converter to ensure that it reaches its life expectancy. This equipment can notify you if emissions levels are too high by taking readings at the exhaust pipe. An exhaust analyzer costs between $2,000 and $6,000.
