Ecu Problem
New to this site but looking for some help from someone with experience. So I have a 06 4Runner sr5. I scanned it the other day before scheduling my inspection. It threw several codes with exhaust inefficiency and 02 sensors. It also said the ecu was bad. I believe the ecu is the reason it is throwing all of these codes. How would you guys recommend fixing this and what type of cost am I looking at? I need to get this fixed soon so I can pass inspection!
Find out for sure just what it wrong !!!

Wyoming9,
I am sure there is something wrong with the ECU. I have cleared the codes several times but they continue to come back along with the ECU code.
However I did replace the cats and 02 sensors last year to get them to go away so I'm pretty sure that they aren't bad which is why I believe its the ECU.

However, it can happen. You can find a rebuilt ECM for about $300 or so. I would recommend checking the codes that the computer is creating. If the codes are nonexistent issues, then it might be the ECM.

It is throwing several codes that I know are incorrect. For instance it is saying that the O2 sensors are malfunctioning when I replaced them recently and just tested them... They are fine. I have enough reason to believe they are bad. Believe I have found a replacement ecm. Has anybody ever replaced one or know if it can be done without taking it to the dealer. I know most cars have to be reprogrammed and have software updates.
