I have had the O2 Sensors replaced twice, the fuel pump replaced and the catalytic converter(s) replaced now 3 times but the check engine light still comes on.... I am at my wits end...is there a software problem with this model just like the Rav4

What is your question?

The car runs fine. It doesn't sputter going uphill or under heavy load pressure. It doesn't seem like the cat is bad or the O2 Sensors. I cannot get it to pass smog like this.

How long has your 2007 Toyota Sequoia had this problem?

months
