Default Help me decode the Prius error codes?

Hi,

I just bought a used 2001 Prius from a dealer about a month ago, and the check engine light came on. I tried screwing the gas cap on further and driving it for a few short trips, but it hasn't gone off yet. To check further, I pulled up the error codes from the diagnostic system and got the following list:

01-D5 340-19-1
01-D9 340-99-2
01-DB 340-23-1

From what I've found online, 01-D5 means component 340 couldn't be found and 01-D9 means component 340 couldn't be started (I couldn't find 01-DB). 340 is a component that I can't find listed, 19/99/23 is a subcode, and the last number for each error is supposedly the number of times it happened.

On a related note, I tried to clear the error codes to see if they'd come up again, but the buttons that would do it didn't actually work. I also tried removing the EFI fuse to see if that would reset the light, but I couldn't figure out how to get it off. Any help?

Thanks!
Adam

Sorry that I'm not sure about Prius codes, but you can take it to any Autozone, Advance Auto Parts, etc. and they'll read the codes and look them up for free. In most vehicles you have to use a code scanner to clear codes. Some auto parts stores will clear them and others won't. Just be aware that if you fix the issues causing the codes the light will go out. The codes are still stored, but since the light is no longer illuminated you know the issue was fixed. Problem with not clearing the codes is that if you get a light later you'll have to be sure it's not being caused by a previously uncleared code.

Those codes came from the diagnostic screen, which can be accessed by a super-secret set of screen button-pressing that I've forgotten. But it is posted several places on the internet.

The secret screens are fun to see but the codes are essentially meaningless.

To get real codes tou need to plug into the diagnostic port by the driver's left knee. Generic code readers (mentioned above) will read the industry standard codes. Toyota also has some proprietary codes, so if something's really wrong you have to go see a Toyota shop.

Generic code readers start at about $60 and I hae now idea of some are better at Prius than others. Typically Toyota shops will charge about the same for their 5 minutes of work.

Adamb, you could disconnect the 12 volt ground lead for 5 minutes and then reconnect it. If the CEL comes back we're going to get the codes, one way or another.

They aren't really meaningless.. many of them can point out wether or not the problems are related to serious matters or not...

Default Best list of error codes

Oops, one of those previous links was embedded and the other was not the error codes displayed by the car. Here is the best list I know of for the car's error codes. This is a DIRECT LINK to a PDF you can print. On my machine for some reason, it downloads the file automatically. Good thing too because the source of the file (which is cached by Google here) has deleted the original. Probably won't be long before they come nocking on Google with Toyota lawyer notes to remove such offending trade secret info!.. :O Get it download it and print it while it's still there...
