Avalon Check Engine Reset?

[cjordan]

I have a 2000 Avalon XLS. The Check Engine light recently came on. After a diagnostic test from a local service center I was told I need to replace the Air Fuel Ratio Sensor (Diag Codes Reported: P1130 & P1135). They told me the part alone cost $680. However I called around and was told their is a Right and a Left sensor and each cost $279 from Toyota. I guess someone was trying to rip me off.

If I relace the sensor(s) myself, will the Check Engine light go off automatically? Is there a way to reset the light?

cjordan,

The light will go off after a short while or a few drive cycles, but the code will remain in the computer's memory. If you have a polution/smog test in Florida, this may cause you to fail the test. It will cause a failure here in Illinois. You can go back to someone with a code reader and they can erase it from memory for you or you can disconnect the battery for a few hours and it should erase the code, however, you will have to reset the radio station presets. Some people say you can remove the ECU fuse for a minute or 2 and this will erase the code without disconnecting the battery and losing the radio presets. I'm not sure about this last one.

I just recently bought a code reader/code eraser at Harbor Freight tools for $40 on sale (normally $50) that lets you read the codes and delete them yourself. I figured this was a good long term investment. If you are interested, it is called a Creader and Harbor Freight's part number for it is 46030. You can go to their website and check it out.

Good luck with the problem.

Hi,

How does the reader from harborfreight tools compare with the actron obd scanner that autozone uses? Thank you.

try disconnectign the battery for 5min and attaching it back on. I did that when my CEL was on and it went away afterwards.
