How to Check the Engine Light on a 2000 Tacoma

The Tacoma is a compact pickup truck that Toyota has been manufacturing since 1995. You can read the codes pertaining to the "Check Engine" light on your 2000 Toyota Tacoma. The On-Board Diagnostics II (OBD II) computer receives trouble codes from various sensors positioned throughout the vehicle. It alerts you to any trouble codes pertaining to the emissions system or engine by illuminating the "Check Engine" light on your instrument panel. You can read these codes using an OBD II code reader. This computerized hand-held device can be purchased from any auto parts retailer. This is an easy job that should take about 10 minutes to complete.

Instructions

1

Find the DLC port on the drivers side dashboard under the steering column. Plug the connective end of the OBD II scan tool into this port. You may have to rotate it to make it fit. Make sure you dont force it in or it may bend the pins inside.

2

Put the key into the ignition and turn it to the "On/Off" position. This powers on most scan tools. If not, find the power switch on the scan tool and turn it on.

3

Select the "Read Codes" command on the scan tool. Wait for the scan tool to display the codes. Write the codes on a piece of paper and look up their meaning in the scan tools manual.

4

Unplug the scan tool and turn off the vehicle. Have the necessary repairs made according to the codes diagnosis.
