In many passenger and light-duty vehicles, automakers incorporated the OBD1 system. It controls the vehicle’s engine, the flow of the fuel, and all the electronic sensors.
Now, after any modification of your Ford vehicles, you may want to reset the machine. And the “check engine” light may continue flashing. So you have to reset the codes.
In this article, we have introduced some easy techniques to reset the codes of ford OBD1. So, you’ll get the whole idea of clearing the codes of Ford OBD1.
What is Ford OBD1
The term OBD stands for “On-board diagnostics.” It’s a self-diagnostic system of any vehicle. It goes through all the electronic sensors of the vehicle and diagnoses all kinds of problems.
Now, OBD1 is a diagnostic system that only supports cars from 1985 to 1995. And it supports Ford, Nissan, Cadillac, Oldsmobile, Chevrolet, GMC, etc. In 1996, automakers introduced another diagnostic system OBD2. And since then to the present, all the cars have an OBD2 system.
Since the present-day cars have OBD2, their system is different from that of OBD1 cars. And so, they have different methods to reset their machine codes after modifications.
How To Clear Ford OBD1 Codes
The reset of the on-board monitoring device eliminates all problem codes within the network. But different cars have different methods to clear the codes. And so, the methods that the OBD1 of a Ford vehicle needs to clear codes are different than that of other vehicles.
There are several ways to clear the codes of Ford OBD1. And they are:
- Disconnect Ground Cable/Negative Terminal
- Jumper Wire
- OBD1 code reader
- Auto-Parts Store Service
- Disconnect Ground Cable
1. Most of the time, people use to clear codes by disconnecting the ground battery cable
- Put your vehicle in KOEO, mode which means, key-on-engine-off.
- Open the vehicle’s hood and.
- Remove the black ground cable, or the negative terminal of the battery with an appreciate wrench.

Caution: while removing the ground cable with a wrench, make sure that the wrench does not get in touch with the positive terminal. It may create a dangerous spark.
2. Jumper Wire
To clear Ford OBD1 codes, most of the people use the jumper wire usually. It is an easy and safe method. It clears the codes only and does not clear other computer memory.
- Open your car’s hood and find the EEC test connector near the fuse box.
- Open its plastic cover, and you will find a tan wire with a maroon tracer inside a little gray connector.
- Bring a jumper wire or a paper clip.
- Put one head of the wire or the clip in the pin of the gray connector, and the other head of the cable or clip in pin #2 of the EEC test connector, which is on the top right of the connector.
- Now, put the vehicle in KOEO mode.
- Remove the jumper wire while the PCM displays codes.
- Then the fuel pump will run.
And thus, it will clear the codes.
Caution: Use a jumper wire that is safe for the Ford vehicles. If not, it may cause damages to your vehicle.
3. OBD1 Code Reader
There are some OBD1 code readers for Ford vehicles that can not only read the codes but also clear them.
- Put your vehicle in KOEO mode.
- Open your vehicle’s hood and take out the EEC test connector.
- Connect the code reader with it. The code reader will read the code.
- Now, press and release the reset button on the reader. It will erase the codes.
4. Auto Parts Store Service
