2006 Corolla. Codes P2716, PO121, PO607 I feel the pressure control solenoid would fix the harsh shifting, but the most urgent issue is the engine stalling while driving. Also the engine running but no throttle. Should I go for the ECM first or replace the throttle/pedal sensor as well? Were there any recalls concerning these three code items?

your best bet is to get a used ecm form a salvage yard it should cost you about 200 dollars that is far cheaper than going to a dealership or a parts store. generally that is what i do when i replace ecms. there are plenty of wrecked vehicles and the ecm is good in them so why pass it up to get a part that cost brand new about 1500 dollars.. goodl luck. please rate this

This is very common on Matrix/Corollas and is repairable by way of replacement PCM to correct invalid parameters. the labor is low but the part is very expensive.

Expect approximately $89 or less in labor, and $648 for the new PCM

Hello.

Before you start looking at replacing solenoids, here is something that you need to know:

Toyota has a technical service bulletin regarding this issue.

Changing the solenoids will NOT rectify your situation. Replacing the ECU in the car is what you need to do. The logic/programming is the problem, not the solenoids.

The good news is this: The ECU is covered, under the factory warranty! It will be replaced for free, if your car has less than 80,000 miles on it.

If you have more miles than 80K, call the Toyota Customer Experience Center at 800-331-4331; an analyst may be able to help offset your costs; they do this quite frequently.

This should get you fixed up. Thanks for visiting FixYa!

Hello. Welcome to FixYa.

No, the P-2716 DTC is not a recall.
It is a software issue that results in a 'false code' being generated.

What Toyota is doing is replacing your computer with an updated unit; the programming in the current computer needs to be changed, and the Corolla computer you have cannot be 'reflashed', it must be physically changed out.

If you car has less than 80,000 miles on it, the replacment will be free.
Get in touch with your local toyota dealership, and they will get you a new computer.
