There is a relay shown in the diagram that is for the PCM ( Powertrain Control Module ) power located in the power distribution box in the engine compartment The locations are not numbered , so here goes : The PCM Power RELAY is in the second row from the drivers side , and in the third spot from the front of the PD BOX ( it is one of the physically larger RELAYS ) Ford recommends disconnecting your battery cables before servicing anything in the PD BOX
EEC stands for Electronic Engine Controls. The EEC Relay provides power to the computer.
A 1994 Ford Explorer is EEC-IV / OBD I ( there is an EEC test connection in the engine compartment near the power distribution box )
A 1994 Ford Explorer is EEC-IV / OBD I ( there is an EEC test connection in the engine compartment near the power distribution box )
A 1994 Ford Explorer is OBD - I / EEC -IV , there is an EEC TEST connection in your engine compartment by your power distribution box
On a 1996 Ford Explorer : The Powertrain Control Module ( PCM ) power relay is located in the Power Distribution Box ( which is " live " ) located in the engine compartment near the brake fluid reservoir It is one of the three LARGE relays It is in the 2nd row from the drivers side of the vehicle and it is the 1st LARGE relay from the FRONT
the injectors does not puls what caus it and where are uhay
I don't believe a 1994 Ford Explorer has a knock sensor - OBD I / EEC IV system
What does the EEC test port have on the plug end and what does it do
The 1996 Ford Explorer is definitely OBD II / EEC V , my late 1995 Ford Explorer has both the EEC TEST connection in the engine compartment for OBD I / EEC IV but it also has the Data Link Connector ( DLC ) under the steering wheel for the newer system which has confused some of the newer technicians ( and myself )
In a 1997 Ford Explorer : The Powertrain Control Module ( PCM ) power relay is located in the Power Distribution Box ( which is " live " ) located in the engine compartment near the brake fluid reservoir ( it is relay # 5 , one of the large relays , in the 2nd row from the drivers side , and the 1st large relay from the front end of the P D Box )
On a 1993 Ford Explorer : The EEC TEST connection should be in the engine compartment by the Power Distribution Box * located in the engine compartment , on the passenger side , and I BELIEVE it is BEHIND the PD Box
Your EEC test port is in the engine compartment by your power distribution box EEC IV / OBD I system
