SOURCE: unlock antitheft code for 2004 chevy impala

Radios in the 2004 Impalas are tied to the vehicle's VIN through the computer, so it may be somewhat difficult to get the code. However, the following steps should work:

1. Press and hold the buttons for presets 1 & 4 (may be 2 & 3). The word "SEC" should show.
2. Press the "MIN" button. "000" should be displayed.
3. Press the "MIN" button again to have the second two numbers appear. Record these numbers.
4. Press the "HR" button for the first two numbers to appear. Record these numbers. -- Note: Your number sequence should be the numbers from the "HR" button followed by the numbers from the "MIN" button.
5. Call 1-800-537-5140. This will get you to the GM unlock code automated line. Ignore the prompt and enter "202108#". Next enter your code (remember, HR then MIN) followed by the * key. For example, 1234*. A 3 or 4 digit code will be given to you. If you get a code such as 0532, drop the zero when entering it into your radio.
6. Enter the code into the radio IAW the applicable manual.

SOURCE: code p0455 evap emission (large)

have the gas cap tested or just replace it, then disconnect the battery for 5 minutes to reset the code, then drive it for a few miles and see if problem comes back, if it does a trip to the dealer is in order, as this may be covered by your emission warranty which is good for 70,000 miles.

SOURCE: 2006 5.3ltr chevy silverado z71 p0455 andp0449

These codes are for the evaporative emission system.The 455 is the vent solenoid.The 455 is a large leak in the evap.system.The vent solenoid I would replace because they go bad and will not work because they are under the vehicle in the rear of the truck.There is a bulletin for these and the vent valve is installed in another spot.The number for the bulletin is 02-06-04-037E.You should also look for a broken or loose hose or pipe that might have came off.Specially if you ran over something.If none found it could just be the vent solenoid stuck in the venting position.Good luck.

SOURCE: Received P0455 Evap System Large Leak Detected - 2004 Cavalier

your problem is probably a vacuum hose that goes from the purge valve to the gas tank (crack or broken hose). There should be two of these check both. A broken vacuum line will make the purge valve make a clicking noise that can be mistaken for noisy engine valves.

I have 3 codes on my 08 impala; P0455 P0521 P1174


The 455 and 1174 are probably related to the same issue---emissions and air to fuel mixture which could be a purge valve for the evap. system and the 521 is usually a bad oil pressure sensor.

Code p0455 2006 chevy impala


That code is for a large EVAP leak. The first thing I would suspect is a bad EVAP vent solenoid. You should be able to find it up under the car behind the drivers rear wheel. Remove it from the vehicle. use jumper wires to supply power and ground to the solenoid. You should hear a definite click and you should not be able to blow through it. If you do not hear a click and you can blow through it replace it.

How to fix a p0455 code on a 2008 chevy impala?


There is no magic bullet fix for this, you can have a leak you can't see or a defective fuel tank pressure sensor or a defective vacuum line, the list goes on.

Po455 trouble code


It is a leak in the fuel evap system. This can be caused by a loose gas cap. If the cap is not loose then there is a leak in the system. That model Impala is known for the return solenoid going bad. It is located by the gas filler. They run about $40. I have included a link from a forum that may help you if you are mechanically inclined.

I have a 2010 Chevy impala. Reduced engine power and check engine light also comes on but won't stay on. Codes are P2138 P2122 P0455


Hi Rosalee_IM,
The codes your vehicle is storing are for low voltage from your accelerator pedal position sensor and a gross evaporative emission leak. The code P2122 and P2138 are directing you to test the accelerator pedal position circuit and/ or sensor. This is the cause of the reduced power concern you are feeling.The P0455 is telling you there is a large leak in the evaporative emission system. The most common cause for this code is a loose or incorrectly installed gas cap.I hope this helps clarify the concerns you are experiencing. If you'd like more information on how to trouble shoot the problems,drop me a line. Please include the model Impala you have,(LS,LT or LTZ) and the engine size. I will do my best to get back to you as soon as possible.Thanks, Chuck

Same 3 codes , p0455, p0442, & p2138 on my 2009 Chevy Impala and brought the car to a General Motor or Buick Dealer Service Department to replace vent solenoid or solenoid fuel tank evaporator control . Also replaced gas pedal position sensor.

P0455 comes back on ,we try to fix it


The EVAP control sytem is checked by the ECM upon the first start of the day when the engine is cool and will trigger the DTC code P0445. If you have a vacuum line leak when it's cold and seals it self when it warms up then the code will stay there. After warming up the car reset the ECM to clear any DTC codes and see if any MILL shows up. IF not then there is a leak only when the system is cold so your going to have to try to do a smoke test when the system is cold.
The other thing is to check all the vacuum lines and fittings around the canister and fuel tank for any lose clamps ECT.
Good luck and keep me posted. Be glad to help you

On a 2006 chevy impala it tells you to tighten the gas cap ,then when you do, we shut the car off. Then check engine light comes on. Where is the sensor located.


There is no sensor for a loose gas cap. What is happening is that the evaporative emission system is sensing a "Large Leak". Usually code p0455. The computer sees this as the most probable cause is a loose gas cap depending on several factors it looks at. You would need to clear the code(s) and see if that was the problem. If the light comes back on, then you have a problem in the system that will not let it seal. Possible solenoid problem, leaking hose / line, etc.
