One problem related to check engine light on has been reported for the 1998 Lexus ES. The most recently reported issues are listed below.
Since may of 2019 my check engine light has been on. The obd reader keeps detecting a trouble code. When moving back to California, I had to reregistered for California license plates, tags, and get my car smogged with my smog certification in order for me to complete registration. I have spent so much money into my car that it's affecting me from getting to work/ school and taking driving my daughter to school as well. Every time I get something fixed and drive the miles I'm supposed to be driving, that check engine light comes back on with a trouble code. This is affecting me because I'm unable to drive my car because it still won't pass smog. It's been going on quite for some time.
