There is no "knock sensor" on a 4.0L engine
No. It only senses engine vibration/knock.
No it will not.
Usually, it is located on the very back, top of the engine, near where the engine and transmission bolt together. There is no knock sensor.
As far as I know , the 1994 Ford Explorer - 4.0 L - OHV engine does not have a knock sensor ( in 1996 when Ford went to OBD II / EEC - V the knock sensor was added on the 4.0 L - OHV engine )
I drive a 1995 Ford Explorer and as far as I know it doesn't have a knock sensor My Haynes repair manual engine wiring schematic shows a knock sensor on the 1996 Ford Explorer - OBD II / EEC V system
Worn main bearings sometimes knock when cold starting
I don't think it has a knock sensor ( I know that the 4.0 liter V6 engine in my 1995 Ford Explorer doesn't have a knock sensor )
I don't think it has a knock sensor ( I know that the 4.0 liter V6 engine in my 1995 Ford Explorer doesn't have a knock sensor )
It doesn't have a knock sensor on the 4.0 L OHV in a 1993 Ranger ( my 1995 Ford Explorer 4.0 L OHV engine doesn't have a knock sensor either )
Some cars will knock for th first minute or so on a cold start until the oil starts to circulate through the engine
I don't believe a 1994 Ford Explorer has a knock sensor - OBD I / EEC IV system
