first up i would replace air filter and fuel filter then get engine tune up if nothing has been changed on vehicle, you should not have to change sensors
They are replaced when they go bad.
There are 3 oxygen sensors and all 3 should be changed for the best performance and fuel economy. ON THE 1995 Ram there is only one O2 sensor on the cat
no they will not. I have replaced them on various vehicles. They are designed to be replaced if necessary and serviced as such. Static electricity precaution should be observed though such as touching the car bdy or metal before unplugging sensors as a rare possibility could exist. Most airbags components are normally serviceable without danger of setting airbags off.
If the oxygen sensors for the 1991 Chevy 4.3 is running rich when it is warmed up it is best to have the sensors replaced. Once the sensors are replaced this should resolve the issue.
Have you had your 4 oxygen sensors replaced? It turns out when they replaced my oxygen sensors, they were after market parts so the service engine light did not come and gave codes even though they were replaced.
Tires do not have oxygen sensors. They can have pressure sensors. The lack of pressure sensors would have no affect on fuel economy.
No, they will need replaced if defective.
If one of the turbine speed sensors is malfunctioning locate the broken part must be found. This is done by using a diagnostic machine. A broken sensor will need to be replaced in order for the components to work correctly.
They read the speed of the input and output components of the transmission.
As far as I know they can not be cleaned. Must be replaced.
Identify and remove freon. Remove the failed compressor and transfer the brackets, sensors, manifolds and switches to the replacement unit. Clean components that are not being replaced. Replace the dryer or accumulator. Install the new compressor.
All sensors, air pump, and EGR
