ECM Processor Error

My check engine light was no for a couple of days, then went off, and has stayed off since. From the advice in my original thread, I took it to Autozone. The diag test came back with :

ECM processor error

Probable cause - Failed ECM

As I said, the C/E light is now off, and I have observed no oddities of any sort. Recommendations? It's an '06 V6. A quick scan of the internet shows me that these things are $500+. yuck.

 

I'm sorry to here that. You should get a second opinion.I replaced the ECU a couple months back,cost me $950.00 that not include the labor/tax. I hope nothing like that with your.'06 shouldn't have that problem.

 

This is the kind of issue that should probably be referred to a dealership shop. Toyota is the only outfit that can determine if the ECU is definitely faulty.

 

Is the ECM considered part of the powertrain?

 

Most ECM's are under a 8 year 80,000 mile warranty. If you are within the time or mileage take it to the dealer. Most likely it is covered. ECM's are not a powertrain item. Powertrain consists of internally lubricated parts within the engine and transmission, including bearings on the drive axles. For instance a front wheel drive vehicle will have a 5 year 60,000 mile warranty on front bearings and 3 years 36,000 miles on the rear bearings.
