Having problems with your 2003 Toyota Tacoma ?
Check engine light on my 2003 SR5 V6 came on. What is the cause?
The check engine light could come on for numerous problems. Sometimes, It's the oxygen sensor gone bad. I believe there are two of them located under the vehicle. Sometime you can find them and just pull the connection apart and blow dirt or anything out of the connection and hook it back up. Most times, you have to replace the sensor or sensors. If the check engine light is blinking, there is another problem besides that. I would try that first or go to a mechanic and let them run a computer test on your vehicle. That should not cost much and will take less than 10 minutes. This is a very vague answer in the many check engine light problems, but it's a start.
