It means the car has not reached operating temp. The computer wants the engine a certain temp so it can go into "closed loop" where it fine tunes the fuel mix for optimum economy and emissions. If it cannot reach that temp it sets that code. You either have a low coolant level or a stuck open/missing thermostat.

Remove or disconnect the following:
Air outlet duct Coolant Inlet radiator hose from the water pump Upper fan shroud Cooling fan and clutch assembly Drive belt Radiator outlet hose from the coolant pump Surge tank hose Heater hose Water pump
DO NOT use cooling system seal tabs (or similar compounds) unless otherwise instructed. The use of cooling system seal tabs (or similar compounds) may restrict coolant flow through the passages of the cooling system or the engine components. Restricted coolant flow may cause engine overheating and/or damage to the cooling system or the engine components/assembly.
Install or connect the following:
Water pump. Install the water pump bolts. Tighten the water pump bolts first pass to 11 ft. lbs. (15 Nm); tighten the bolts final pass to 22 ft. lbs. (30 Nm). Water pump drive belt pulley and bolts (if applicable). Tighten the pulley bolts first pass to 89 inch lbs. (10 Nm); tighten the bolts final pass to 18 ft. lbs. (25 Nm). Surge tank hose Heater hose Outlet radiator hose to the coolant pump Drive belt Cooling fan and clutch assembly Upper fan shroud Inlet radiator hose to the water pump Air inlet duct Coolant

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.
Assuming you put on the proper gas cap and one of high quality, I would inspect the EVAP system for cuts/holes in tubes/hoses (you may hear a vacuum noise or smell fuel), repair if necessary.

A P1415 indicates a problem with the A.I.R. system. This code is a common indicator of an electric a.i.r. injector reactor problem. Sounds complex but it's not. There are two of these reactors on your engine. They are the black things that the secondary air pipe plugs into at the exhaust pipe/or/exhaust manifold. It is worth changing both of them becauses if one fails the other is not far behind. It is also worth replacing the factory hose clamp with a regular one---you'll see what I mean.BTW--P1415 specificaly indicates a problem with Bank 1 of the A.I.R. system. Make sure both sides of the A.I.R. system are in order--meaning all the hoses are tight and secure--no leaks--cracked hoses ETC.
