I am pretty sure I have one in my garage ... I'll get back to you tonight when I get home if no one else has one.

Keep in mind that it will likely be a generic scan that returns only an error code #. Some of these are standardized with OBD-II and readily translated to words or a specific sensor but others are not. If it is a non-standard code, then you'll want to serach for it with google (or find a toyota car club forum) to decode what it means. My random guess is an oxygen sensor

Go see Paul @ True Tech Auto on Steeles, straight across from Bomar. That guy will tell you whats wrong in about 5 minutes.

It's not usually that complicated. As I wrote, a quick google search usually returns a description of the problem and finding a forum thread detailing how to fix it is usually only a few clicks away.



Personally, I like to think that >1% of the people who buys a scan-tool goes on to use it and repair the car themselves. At the very least, they are likely to have a better grasp of what is wrong when talking to their mechanic and are less likely to be deceived.



I'm sure your friend is a fine mechanic but if you can repair something yourself, then you don't need to pay for the shop time

P1125 Throttle Control Motor Circuit.
.

Yawn.

I'd expect a fault with the throttle control system would be associated with acceleration symptoms that go beyond a lit check engine light. If not, I'd start by clearing the code and seeing if it returns. FYI, that's not a great example given the OP stated he had a 99 Toyota Corolla. In his car, such a code is unlikely given the throttle mechanisms consist simply of a throttle body, cable and pedal. FYI, unlike some newer Toyotas where the pedal signal is digitized and the throttle body is indeed driven by a motor, a 99 Corolla uses a cable to manually control the throttle. Quite simple really. As for where to start when diagnosing a problem, take a look over at toyotanation.com.

I think it is fasinating that so many people here think that DIY work (whether it be their house, car or back yard landscaping) is really that difficult. Your simply spreading FUD in your posts above. The OP wanted to find out the engine code and give it a go himself and all you have to offer is that he should pay your friend the mechanic... that's not much of a help in my opinion.

I learned to fix things by watcing/helping my father and plan on giving my kids, nieces and nephews the same opportunity. I began repairing small engines (and eventually cars) by going to the library and borrowing Haynes manuals and following the instructions as a young teen. Today, all you really need is a free login to a good chat room or web forum. Sure, it takes some time, patience and a few tools but it's both rewarding and cost effective. If you'd rather not bother with it yourself, that's fine. But don't go around trying to convince everyone else that it's soooooo complicated. /rant
