While your automobile's emissions and transmission systems may seem unconnected, the point is that original cars are so intricately networked that one can easily impress the other. The O2 sensor detects this temperature aberration and notifies the machine.
Computer De-tuning
Upon detecting severe converter blockage, the machine Testament automatically intersect timing and the air/fuel ratio to prevent engine damage and exhaustive converter melt-down. This "limp home" mode can also include changes to the transmission programming to reduce load on the engine.
Diagnosis can be tough, on the contrary canny how your van works is a acceptable commence.
Blocked Converter Detection
All cars produced after 1996 include at least two O2 sensors, one before and one after the converter. Blocked catalytic converter passages Testament strength exhaust heat to Way out concluded the remaining passages, trapping it inside the converter and causing its internal temperature to skyrocket.These changes can include locking out the overdrive, changing shift firmness, reducing shift RPM and changing the torque converter lock-up point.
Other Effects
A blocked converter can reach over 1,200 degrees Fahrenheit internally, and eventually the torque converter case can begin to glow red hot. These kinds of temperatures can easily boil transmission fluid if the converter is too close to the transmission or transmission cooler lines. This can manifest as torque converter slippage, clutch slippage, excess RPM and possible outright transmission failure.
