Having problems with your 2000 Lexus ES 300 ?

Bad sensors on 2000 Lexus ES 300

\015 My 2000 ES 300 has 93K miles on it. I have always done schedueld maintenenace very regularly. Recently I started having several problems related to sensors. \015\012The break light indicator goes on and off randomly when I am driving. The local lexus dealer checked it out and said the break fluid level sensor is out and it costs $403 to replace it. The break fluid level is fine.\015\012The check engine light and TRAC OFF light indicators used to go on and off randomly but they stay on always now. The dealer cheked this out and said Mass Airflow sensor is out and it costs $683 to fix it.\015\012I have had other sensors related problems in the past and had them fixed. I asked the dealer to check the electrical system and see if there is a problem that is causing these sensors to go bad. He said he didn't find any problems with the electrical system.\015\012My air conditioner also stopped working. It blows hot or warm air, just not cold. The dealer said he needs to replace the compressor and valves and other components that cost $2400. AC is fully charged and there is no leak.\015\012Are this type of problems common for 2000 ES 300 with just 93k miles? \015\012The prices for repairs seem to be very high compared to my previous repairs. Are these prices reasonable? Can I get these parts replaced from a Toyota dealer for less? Are there any less expensive options? Thanks\015 Posted / edited by AnonymousUser on : 19-02-2018

Answers :

It is not likely an electrical issue, just age and low mileage. A Toyota dealer can work on the car but the parts will cost the same. Ask if there is a rebuilt AC compressor to fit. Toyota labor will be less but not much. The under hood sensors do age and foul.Yours may be from to little driving at high speed I would try some really good injection cleaner, fuel system flush and a run with premium gas fro a few weeks. It may help. You may also have a dirty throttle valve in the intake area accessible by removing the snorkle beyond the air cleaner.
If the dealer has scoped this car with his equipment the diagnoses is likely accurate. Ask him to point out the defective sensor under the hood. Several area s easy to do as spark plugs. VERY visible.but when the delaer finsihes he will agin scope the car to check computer readouts.
The fluid sensor may be visible too. Ask at the parts desk to show you on a screen where this item is and if it can be a DIY fix....
I have a 2000 ES300 with 160K on it. It blew 3 coils within the last year, all on the same cylinder #4. Any clues?
