2001 Lexus Es300 Trouble Codes

[oxfordlexusman]

My 2001 ES300 went from running smoothly on the highway to cutting out every couple of minutes for a few seconds. The engine would run smmothly between "cut outs" and there were no accelleration issues. The "cut outs" would then happen at any speed.

The Trouble Codes that showed up were: 1135, 1155, 1354, 1351.

Any help in what to do would be appreciated.

oxfordlexusman,

Google search each code for your year and model to get a starting point. For instance "2001 Lexus DTC 1135". Do the same for each one.

Keep in mind that these will be just starting points as to where to look for the problem. Don't rush out and buy any parts, because most people who go that route end up with the problem they had at the beginning, but have just dropped several hundred dollars replacing a part that was not the issue to begin with.

After you find the code meanings, then find a good independent mechanic who you can trust (through friends), and explain your issues. Many times a good mechanic has solved this same issue and can read between the lines, to zero in on the real cause of your problem. Experience is the best teacher here. It will pay dividends in the long run.

There are too many people who get the free code reading at Pep Boys or similar and just buy the suggested part. Then they discover that the part didn't need replacing, but something else in the same system caused the issue, like a bad ground wire. They could have spent $15 and ended up dropping $150 instead. Good Luck!
