P1281
Engine is Cold Too Long
Engine coolant temperature remains below normal operating temperatures during vehicle travel (Thermostat).
P0455 (M)
Evaporative Emission Control System Leak Detected (large leak)
A large leak has been detected in the evaporative system. See TSB 25-001-02. Also, possible faulty or loose gas cap. Note: The respective Powertrain Diagnostic Procedures Manual will direct the technician to determine if the vehicle evaporative system has an external system leak. Examples of some external system leaks are: a loose gas cap, a disconnected evaporative system hose, or a loose hose connection. Remember that the evaporative system may also have an internal system leak. This internal leak may be caused by an intermittent or permanently stuck open Duty Cycle Purge (DCP) valve. This leak source is considered to be internal because any escaping emissions enter into the engine system and not directly into the atmosphere, unlike an external leak. An internal leak may cause one of the above DTC?s. Possible causes of a stuck open (intermittent or permanent) DCP valve are: 1. Corrosion due to system moisture or possible water intrusion into the system.
P0455 usually a loose/faulty gas cap or cracked or broken hose to the EVAP canister or purge valve.

P1281 The engine coolant temp is too low probably a bad thermostat.

Hope that helps

My 06 cobalt has these codes can anyone tell me what they mean? Are they an expensive fix? p0446,p0455, p0172


code p0446 refers to evaporative emission (EVAP) system-vent control-circuit malfunction===causes --wiring--EVAP canister purge valve--ECM
code p0455 refers to EVAP system-large leak detected===causes --hose connections--intake leak--EVAP canister---EVap canister purge valve
code p0172 refers to system too rich, bank 1===causes intake blocked---EVAP canister purge valve--fuel pressure ---EGR system---injector/s ---ECM
because the EVAP purge valve appears in all codes I would be inclined to change that unit first the run the fault codes again

Hi...Code P1281 means the engine is staying cold too long - check your thermostat. It is possible your thermostat is stuck in the open position.

Hope this helped,

P0455 = Evaporative Emission Control System Leak Detected (gross leak)

What does that mean?

This indicates a fuel vapor leak or lack of purge flow in the EVAP control system. It means a large leak has been detected. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.
Symptoms

You likely won't notice any drivability problems.

Causes

A code P0455 most likely means one or more of the following has happened:
  • A loose or improperly affixed gas cap
  • A non-conforming gas cap (i.e. not factory/original brand)
  • Other leak or damaged piece in EVAP system

Possible Solutions

With a P0455, the most common repair is to:

  • Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
  • Otherwise, replace the gas cap, and/or
  • Inspect the EVAP system for cuts/holes in tubes/hoses (you may hear a vacuum noise or smell fuel), repair if necessary
All the best

What does the code p1308 and p0455 mean on a 97 850 glt non-turbo model mean


P1308 : A/C Clutch Circuit Fault. You may wanna check the A/c clutch and see if it work properly.


P0455 Evaporative Emission Control System Leak Detected (gross leak) . I think you need to check your fuel Canister and see if the hoses are not cracked or leaking.

I had this code one time P0455 and I check everything and everything was fine and I deleted the Code and never come back again. :-)
