hooked up jumper cables the wrong way
 

Hey everyone. So I had a bad morning about 2 weeks ago. My 2007 camry le v6 had a dead battery. I jumped it with my 98 & hooked up the jumper cables the wrong way. My 07 started but the cel was on & I had no throttle. It would still go into gear & move but only at an idle. I took it to my mechanic where it has been since. He said it's now turning over but not starting. Could I have fried my computer or do the 07s have a safe mode or limp mode? Any help would be greatly appreciated. Maybe it's possible that my mechanic is over looking something simple. Thanks in advance

usually the heavy fuses blow in the engine bay ... thats its safety

the ecu may have its own fuse

if all the fuses are ok

swap out the ecu with the correct one see if it starts

dont know if that model includes the tranny control in its ecu or if it is a separate unit

I don't know what my mechanic checked yet. I've been busy since it's been there. If it's the case Is a new ecu expensive

these camrys have a diagnostics port for your mechanic to retrieve fault codes

should be obd 2 codes
here is the list

with these codes you can narrow down the problem... before buying un-needed parts

ECU... no not usually expensive . but it is an import.... might be harder to find the correct one

ring around your local area and state for a car wrecker that has toyota camrys

you have to ask for the exact one out of a 2007 camry le v6

Usual it is a fuse and not the ECU. Take note the anti-theft system may activate if the battery is disconnected. This will prevent the engine from starting.

The ECU has a part number on it such as 89661-06C40. If needing a replacement get one with the exact same part number as the one on the car. There is an active reselling market for used ECU's. Also try Ebay.

Thanks a lot guys for all the feedback. Just got my camry back, was just some fuses. Makes me very happy lol. Thanks again guys

Great to hear its an easy fix for you. Happened too to my brother's '06 rav4 with toasted fuse.
