Question about Toyota Corolla

2 Answers

Hi, I recently saw one of your posts on ecm's for corolla. I bought a used ecm for my 2007 corolla LE. Its exactly the same as already installed on my car. When I replaced it, I could not start the car, (the car starts when I put the old one back) wonding if you might know if its a bad ecm or I just need to get it programmed? Thanks for your help

    Yeah I was thinking about that, So most likely you think I will have to program the ECM at dealership so I can start it? I still can return the ECM, but when I bought it they said it was tested and is in perfect condition. So it might be just like you said. I just though I would be able to replace it without any programming.

Suspect the engine imobilizer may linked to the old ecm and possiibly your key, so the new ecm may need to be programmed. Similar to trying to start with a non programmed key

I have a 1998 toyota corolla with a trouble code p0500- vehicle speed sensor malfunction- I recently replaced my engine with a used engine, that is still under warranty, is this something to do with the...


Hi.

In ordinary conditions the engine replacement should not result in VSS error. TI could not find any bulletin about ECM (the car main computer) reprogramming after engine swap but the VSS signal passes through two modules, the ABS and the ECM. If you have replaced the engine you may need to re-flash or re-program the ECM . There are a couple of forums where users complain about the same problem.The job can be done at the dealer place.

Before reprogramming the ECM do the regular troubleshooting for P0500. The problem could have been already there before the engine swap, the VSS or the VSS wiring may also have been damaged in engine replacement operations. Check the VSS mounted on transmission, Ohms are between 500 and 700, check also volt output on bridge. Check VSS wiring to ABS module and ECU and check the two-wire connector to VSS (check volts) . Check ECU connector. Check PNP switch.

Regards.

I have received a Toyota Corolla 2007 maintenance code P2716 and wonder what this means?


Hello; welcome to FixYa.

The P-2716 code you speak of is a problem in the logic (programming) in the car's Computer, or ECM.

Toyota is aware of this issue, and have issued a Technical Service Bulletin regarding that DTC Code; P-2716.

If your car is under 80,000 miles, Toyota will replace the ECM for you, for FREE. The ECM has an 8-year/80,000 mile warranty.

We here at FxYa hope this helps you out.
Thanks for choosing FixYa for advice!

Hi, I believe their is a TSB for your model. You'll want to check with the dealer because if the ECM needs replacement it should be covered under the emissions warranty. More info @ P0607

Steering wheel of my Toyota Corolla LE 2007 vivrates


Hello. A vibration in the steerign wheel indicates an issue with the front tires. They are either out of balance, and would need to be rebalanced, or it is possible (although remotely) that the tire(s) may be compromised (after hitting a pothole), the belts in the tire may be corrupted. What I would suggest is to take the car to a reputable tire place, and get the balance checked. While the tire is on the balancer, the Tech will be able to see if the tire is out-of-round due to possible road damage. Probably just a tire balance problem. Thanks for choosing FixYA for assistance.
