How To Replace Your Transmission Breather Hose Cap

- In this video a simple way of replacing your transmission breather hose cam is demonstrated. This breather hose cap is important to the transmission because it allows any pressure built up in the transmission to be vented. A damaged breather hose cap can be displaced causing the hole in the hose to be exposed and allowing water to enter your transmission. Water mixing with transmission fluid will damage your transmission.
My breather hose doesn't have a cap...
@@jeffj6815 if it doesn't have a cap and the hole through the hose is exposed upwards you need to cover it but not to seal it off. Contaminants can pass through it into the transmission.
Video shows nothing
Don't remove the cap just pull it out easily
P0420 check code I keep getting it.
This code P0420 usually appears when your oxygen sensor/s is not working correctly. You can identify this bad sensor by using the graph function on a scan tool that has this function and look at the fuel trim. While the engine is running and vehicle in park and the fuel trim graphs in site press the accelerator pedal. You should see the graphs moving simultaneously. If you press the pedal aggressively and release and the graph/s doesn't move much, the sensor related to that graph may be the problem.
@@ShelDockToyotaVitz I don't have a scan tool of that capacity but it usually states it's bank 1.
@@paulwilliams7951 If you have only 1 exhausted as in a 3 cylinders and 4 cylinders bank 1 refers to all oxygen sensors on that one exhaust. If you have 2, 3 or 4 oxygen sensors on this exhaust it's still bank 1. When you have bank 2 its referring to the second exhaust as in a 6 cylinders or 8 cylinders engine. Find out which of these sensors are faulty. You should take the vehicle to a auto electrician with a proper scan tool to correctly diagnose which of your oxygen sensors are faulty.
@@ShelDockToyotaVitz it's three cylinder like yours each time I check the two sensors there is soot all over the head 'black' keep cleaning them.
@@paulwilliams7951 seems like you have heavy oil consumption as this is the usual cause of black oxygen sensor tips and it eventually blocks up the catalyst converter.
