Is the oil pressure sensor important?
The oil pressure sensor assumes the role of monitoring this internal pressure and sending a signal to the oil pressure gauge on your dash, alerting you immediately if there is a problem. This gives the driver time to pull over and assess the problem before costly repairs become necessary. via
What causes high transmission pressure?
High pressures and sticking valves usually come from gummed up control surfaces or gunk in your transmission. This can often be remedied by a transmission fluid flush and a new filter if your transmission is so equipped. via
Can you drive with a messed up speed sensor?
However, when it comes to wheel speed sensors, a minor-seeming glitch may turn into a major safety risk. That is why in general, it is unsafe to drive a vehicle with a broken wheel speed sensor. via
Can speed sensor make transmission not shift?
Without a valid speed signal from these sensors, the PCM will not be able to correctly control the shifting of gears within the transmission. This may cause the transmission to shift roughly or more quickly than normal. via
