I don't believe a 1994 Ford Explorer has a knock sensor - OBD I / EEC IV system
Ford did not start using knock sensors on the Ford Explorer engines until 1996, when they switched to the EEC-V system.
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 )
There is no "knock sensor" on a 4.0L engine
how do you replace the overdrive sensor on a 94 ford explorer
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
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 )
There is a crankshaft position sensor , at the front of the engine
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 )
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.
I'm not a mechanic / technician but the engine wiring schematic in my Chilton repair manual for the 2.3 in a 1994 Ford Ranger does not show a knock sensor
It is in the differential and secured by a 10mm bolt.
