On a 1999 Ford Explorer Sport ( and 4 door models )
The Powertrain Control Module ( PCM ) is " hidden " behind the glove box
From the engine compartment you can see where the wiring harness is
bolted to one end of the PCM as it passes through the firewall
towards the passenger side of the engine compartment
Ford did not start using knock sensors on the Ford Explorer engines until 1996, when they switched to the EEC-V system.
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 )
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
At the EEC test port located by your power distribution box in the engine compartment - OBD I / EEC IV system - Helpfull
The EEC test fitting is in the engine compartment by the power distribution box - EEC IV / OBD I system (Helpfull)
A 1994 Ford Explorer is OBD - I / EEC -IV , there is an EEC TEST connection in your engine compartment by your power distribution box
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 )
Your EEC test port is in the engine compartment by your power distribution box EEC IV / OBD I system
That's the Electronic Engine Control - series five for emission control It started with the 1996 model year of Ford Explorer
