First off let me tell you the history of this car. The kid I bought it off of basically tried to supercharge it then ran out of money before installing everything and took everything off, but left random parts on it still like the vortech fmu, the crank pully, and all the vacuum lines for the gauges. Its been sitting for around 5 years because the kid couldn't get it inspected and couldn't pay to get it fixed. plus he was in the army and couldn't drive it while he was deployed in iraq.

Here is what i've found out so far

P1457 Evap emission control system leak detected
possible causes vapor canister saturated, failed vent solenoid, and failed purge solenoid
I think i know how to fix it because i did a lot of research on it through search. don't say loose gas cap because that is 1456.

P0141 secondary o2 sensor heated oxygen sensor bank 1 is what it says for this one
could this be because my o2 sensor is bad? my uego wideband is reading 14.6-15.4 and jumps back and forth while i'm cruising dips down to 13.3 and goes all the way up to 16 sometimes when im accelerating. I have another o2 sensor being sent to me so i'm going to try and install that to see if the cel comes back

P0410 secondary air injection system fault
P0411 secondary air injection system fault.
no idea what could cause these two but seem to be similar.

Thanks for all the help in advanced. 1457 is like a weird topic because no one has seemed gotten it fixed besides a few people.

 

1457 might be the tubes on the top and the front of the engine. They might be routed incorrectly, and there is also a one-way checkvalve, it might be facing wrong way.

410 and 411 are pertaining the air pump, the one under the driver-side headlight. Just look for a Bentley repair manual online, you can probably find one for free. It'll tell you how to check the airpump, and how the hoses from it are routed.

 

Thanks I opened up the fuse box and it was blown or the airpump..... I'm going to replace that fuse and see what happens with the two codes.

 

fixed the evap problem now just need an o2 sensor to fix

 

You don't need an O2 sensor... your fix is pretty simple.


Head down to Radio Shack, pick up a pair of 10ohm, 1W resistors. Attach them in series to the heater pins on the OEM O2 sensor connector (hopefully it's still there - the harness is attached at the top/rear of the tranny) for a 20ohm load.

 

how did you fix the 410 and 411 code? i am having it too.
