Where is EEC relay located?
Where is EEC relay located?
EEC relay is located behind the passenger side kick panel of the console on the ECU bracket. There will be two relays attached to the bracket a green/black one which is the fuel pump relay, and a brown/black one which is the EEC relay.
What is the EEC relay?
The EEC Power Relay not only supplies battery voltage to the fuel injection computer (also known as the E.E.C. Electronic Control Assembly), but also supplies power to the fuel injectors, the fuel pump relay, and a few other emissions related solenoids. stands for, it’s: Electronic Engine Control.
Where is the fuel pump relay located on a 98 Ford Explorer?
The location is somewhere up under the dash. My 98 Wiring Manual says “near the radio” but the Ford IFSO switch is often found in the front passenger footwell above the top edge of the carpet or behind the passenger side kick panel. The 2 relays direct power to the fuel pump among other things.
Why does the Ford EEC power relay activate?
As soon as the EEC Power Relay get’s power (on circuit 2 ), the relay activates. The EEC Power Relay activates because its low current circuit is grounded 24/7 (all of the time) by wire 1. In this test section, we’re gonna’ test circuit 1 but there are some very important precautions you have to take:
When did the Ford Explorer fuse box come out?
In this article, we consider the second-generation Ford Explorer, produced from 1996 to 2001. Here you will find fuse box diagrams of Ford Explorer 1996, 1997, 1998, 1999, 2000 and 2001, get information about the location of the fuse panels inside the car, and learn about the assignment of each fuse (fuse layout) and relay.
What is the low current circuit on a Ford EEC?
Every Ford EEC Power Relay has two basic circuits and for the purpose of our discussion, we’ll call them: A low current circuit. This circuit can be identified by the wires labeled with the numbers 1 and 2. The low current circuit is the control circuit that ‘closes’ or ‘opens’ the high current circuit.
How does the EEC relay in a fuel pump work?
Relay Basics: How The EEC Power Relay Works. This is the circuit that delivers the voltage (and thus current) to the Fuel Injection Computer (EEC Electronic Control Assembly), fuel injectors, fuel pump relay, etc. When the relay is not activated, this circuit is ‘open’, and as such, does not send any power to anything.
How to test the Ford EEC power relay?
The next step is to verify that the EEC Power Relay’s high current circuit is being fed with battery power too. Go to: TEST 2. CASE 2: Your multimeter DID NOT register 10 to 12 Volts DC. Double check that you’re probing the right wire and repeat the test.

What’s the color of the EEC power relay?
The EEC Power Relay is easy to recognize because it’s usually a brown color. If the EEC Power Relay has already been replaced, you can still recognize it by its brown colored connector. In this ‘How To Test’ article, I’ll show you how to test it on your Ford car or pickup in a step-by-step manner.
Can You Back probe an EEC power relay?
You can back probe the EEC Power Relay connector. Or pierce the wire with a wire piercing probe (to see an example of this, click here: Wire Piercing Probe ). NOTE: It’s best NOT to probe the front of the EEC Power Relay’s connector or you run the risk of damaging the metal female connector inside.
