My 99 Honda has an OBDII code P1457 print out says "unable to pull vacuum in tank" looked it up inline and it says "leak detected in EVAP control system." Could this be why I'm burning so much oil? Is this part of the ECG? My friend told me it might be the "charcoal Canister," does this sound right? Will it cost alot to fix? Please help me!
I would really like to know if this is my oil problem thanks!

 

No, P1457 wont make your oil burn

The Evap System is used to filter out fumes from the fuel system ( tank)

It wont make your car run bad or make you burn oil,

That code means you have a leak in the EVAP system or hoses somewhere..

How many miles does your car have on it?

Bad piston rings, can cause oil to leak by and burn, or valve stem seals

 

Its a 99 with 131,000 miles on it. When I read the code it said something about an ECG? Myabe I have more than one code problem?

Codes above P0999 mean different things from one carmaker to another. If the code reader was last used on a Ford or Chevy, maybe that ECG business was for one of those.

 

now my car shuts off when I dont have my foot on the gas. Sounds like EVAP, guess im gonna bite the bullet and send it to mechanics. You think oil burning is bad seals, but no blue smoke coming from exhaust. Can it still be the seals? guess Ill have them look at that too. thanks for your help!

 

Well, the oil burning shouldn't be related to P1457. P1457 is a leak in the canister section of the EVAP system. You can check a few things...

EVAP purge solenoid valve is on the firewall near the throttlebody. Unplugged? Vacuum hose leaking?

The EVAP canister (charcoal canister) is forward of the gas tank, about underneath the left-rear seat. Disconnected vacuum hoses? Unplugged solenoid valve? Anyone work down there & forget which hose goes where?

One popular valve to fail is the EVAP vent-shut valve, which is mounted into the outboard end of the EVAP canister. When I tested mine by applying power directly from the battery, it didn't even click. The TRUE test is to use a MityVac & see whether it holds vacuum or flows thru depending on whether it's energized.

There's about 7 pages of tests for that system in the Helm repair manual; too much to write it all here. But it's pretty straightforward to do most of the checks. You need a multi-meter, some jumper wires, & a MityVac. After ruling out some of the valves & hoses, the worst PITA is a failed fueltank pressure sensor. Gotta drop the tank for that one.

The car shutting off also should not be related to P1457. That EVAP system is only for capturing evaporation from the gas tank. I don't think it can make the car stall. Look elsewhere to figure that one out.
