What should the temp be before and after the catalytic converter?
The average light off temperature at which a catalytic converter begins to function ranges from 400 to 600 degrees F. The normal operating temperature can range up to 1,200 to 1,600 degrees F. But as the amount of pollutants in the exhaust go up, so does the converter’s operating temperature.
What should the starting temperature of catalytic converter be?
please tell me the complete detail about that Catalytic Converter if u have…….. Ok, let the car run for 20-30 minutes. Then use your temp gun, the back should be at least 75 degrees hotter than the front. If the front is hotter than the back, then the cat is restricted.
What is the diagnostic code for a catalytic converter?
An illuminated check engine light or malfunction indicator lamp (CEL or MIL) with a catalytic converter diagnostic trouble code (DTC) is the most common catalytic converter problem indicator.
Can a catalytic converter be repaired without replacing the ECM?
Exhaust leaks are common and can skew oxygen sensor readings without setting other DTCs. A careful search might reveal exhaust leaks that, when repaired, “restore” catalytic converter function, at least from the point of view of the ECM.
How can I tell if my catalytic converter is restricted?
Take note of the vacuum reading with each snap of the throttle. If you see that gauge needle dropping steadily to near zero, most likely the catalytic converter or muffler is restricted. To confirm a possible restriction, loosen the back pipe from the catalytic converter just enough to allow gas to flow through. Repeat step 6.

Here are some tips: What is a Catalytic Converter?
What causes catalytic converter to be destroyed in GMC Terrain?
1. the catalytic converter isn’t destroyed by excessive oil burning, coolant leaking into the exhaust stream, burned out by overheating (excessive lean condition for a long time) and is otherwise doing its job. 2. there wasn’t excessive air (extra lean) in the original combustion mix.
What should the temperature of a catalytic converter be?
Many drivers simply don’t push their vehicles hard enough to heat the catalytic converter to its most-efficient temperature—between 800 °F (426 °C) and 1,832 °F (1,000 °C)—leading to premature failure.
An illuminated check engine light or malfunction indicator lamp (CEL or MIL) with a catalytic converter diagnostic trouble code (DTC) is the most common catalytic converter problem indicator.
