How to Troubleshoot a 2000 Ford Explorer Engine Light
- 1). Connect the onboard diagnostic code reader (OBDII) to the OBDII port located under the driver's side dash panel on your Explorer. You can purchase OBDII code readers at most auto part retailers. If you choose not to purchase a code readers, ask the salesperson if you can borrow the one they have so that you can test your vehicle.
- 2). Turn the ignition onto the auxiliary position. This turns on the Explorer's computer and the code reader.
- 3). Select "Read Trouble Codes" on the OBDII code reader. The OBDII will show you a code on the screen.
- 4). Compare the code shown on the OBDII scanner to a code deciphering book to determine what part on your engine caused the code. You can purchase the book at most auto part retail stores or you can look for an online website such as engine-light-help.com for a list of codes and what they mean.
