Help please. Gas pedal not working.


Recommended Posts

So this is the forth time this has happened in like 3 years. When its cold out the car starts fine I let it warm up and when I start driving (not immediately) I'll get the check engine light and the cruise control light will flash. The car will idle higher than usual and when I press the gas nothing happens no rev the car doesn't move nothing. But if I turn the car off and turn it back on some times 3 trys the car will run fine but the lights will still be on. So I try to go to the dealership or auto zone to get the code ran but it always goes away before I get to one of those places. The dealer says they are not sure based on my description they say they need the code. Would any one happen to know what's wrong or has it happened to anyone here? Thanks in advance.

Drive by wire has issues. Your accelerator pedal runs a rheostat that in turn runs a motor that opens and closes your throttle body. Either the rheostat is beginning to fail, or the throttle body control motor is beginning to fail, or both.

 

You can buy a code reader for about $20.00 at Harbor Freight. It's worth the money because it will fit every vehicle you own and will until (I believe) 2018 when OBDIII is supposed to come out.

OK OK thank you I'm going to go pick one up. It rarely happens I just moved from Texas back to DC so its the first time the car has seen serious cold. And this morning I noticed that when I started the car the thermometer was flashing and I thought that was odd also the other times it happened it was rather cold. But idk I'm going to invest in the code reader. I appreciate the help. I'll contact the dealer and see what's the price on that if you happen to be right.

Temp readout will flash if it's 36F. that's to warn you it may be icing conditions outside.

 

Also any decent repair shop can fix your car, you don't have to go to the dealership.

 

Check the local forums for a good shop near you.

If your going to be working on the car DIY, you may want ot buy a better code reader. some will do more options then a cheap one.

Stupid? Why? Because you are asking questions? Never feel stupid about asking questions. How do you expect to learn except by inquiry and there are enough very smart and very experienced people on these forums that can help you and save you money in the process.

 

Also, what Max said about the code reader. If you do a lot of your own work, then by all means, spend more on the reader. The more you spend, the more it will do (read transmission codes, ABS codes, traction control codes) as well as engine codes. I personally would spend at least $100.00 on a code reader and that would get you a lot of capability but then again, I do all of my own work as well as on the about 65495191 cars my family owns too, so I actually have two of them because it seems that one of them is always in use somewhere. :)

Make sure the battery terminals are clean and tight. They cars do funny things when the terminals are corroded.

I'm a little confused by the grammar and the situation but I don't think 2004 Legacies were drive by wire. My old 2002 is cable actuated.

 

Maybe check the cable at the throttle body?

 

(Maybe I'm missing something and being an idiot in which case I apologize)

A 4th gen is drive by wire, and a 2004 in EU can be a 4th gen regardless of which generation it is.
