Checking Catalytic Converter With Heat Gun

When catalytic converter efficiency degrades to the point that it stops catalyzing exhaust gases properly the catalyst monitor rear oxygen sensor will report it to the computer.

Checking catalytic converter with heat gun. So exhaust gases entering the converter should be cooler than the gases exiting the converter. Following a pre configured procedure the computer will then turn on the check engine light cel or malfunction indicator light mil and store a trouble code. Utilizing a catalyst combined with heat to convert the unburned gases into fully burnt gases. Catalytic converter test quick and dirty with 40 tool vido link of the 4 reasons.

Temperature sensors are used for two purposes. This catalyst is heated by the engine exhaust to excite the chemical reaction. In older models catalytic converters usually take about 10 15 minutes to heat up so they were utterly unproductive for the first few kilometers of a journey. The function of the sensor is to warn of catalytic converter temperature above the safe limit of 750 c 1 380 f.

This action makes the catalyst even hotter furthering the effect into thermo reaction. However in contemporary vehicles it takes a mere 2 3 minutes to warm up though huge discharges can still occur during this period but at least it is far better when compared to. The temperature differential test measures the surface temperature at the inlet and outlet bushings of the converter. Catalytic converter test with snap on temperature gun to see if cat is plugged or if the cat is working properly.

The first is as a warning system typically on two way catalytic converters such as are still sometimes used on lpg forklifts. The conversion process produces heat.
