I have a Subaru Impreza WRX 2006. The check engine light came on and when I took it in to see the error code it came up as Error Code P2444 Fuel Injector or secondary air injector pump. Has anyone seen this code or problem before? The dealership says I need to replace the fuel injector, costing over $1,100 which is ridiculous. I have done some online research and some say I just need to replace a sensor that isn't working properly or that the fuse has blown. Have any of you seen this code error or know what else could be wrong or what to replace? Thanks.
first thing is to just clear this code and see if it returns quickly. Sometimes you get spurious codes that may never re-occur.
Second, look under the hood for a black plastic circular part, driver's side.
(the thing on the right side shown in these images);
Now, on a 'cool' car (first thing in the morning, or parked long enough to be below operating temperature) place your hand on the pump while someone else starts the car. You should be able to feel the pump operate for 20-40 seconds. If it doesn't, it may be bad or there is a bad relay or fuse keeping it from coming on. If it never goes off, could be a bad relay, a bad sensor in the valve or ?????
This pump is part of a system that replaced a front cat conv on previous models. The pump and its 2 valves are only used for a few seconds to help with cold running emissions. This system has been a problem for many folks including myself. i had both valves stick closed. Eventually had to overwrite my ECU ROM to kill 16 codes after pulling some fuses.
If you are a DIYer, and can confirm what parts you need, there are folks pulling these systems out and used pumps/valves/sensors may be available. The valves are a b!tch to replace - particularly one of them. The pump should be easy.
some folks have contacted SOA and they have authorized ealerships to do a 'goodwill warranty' by splitting/reducing the cost.
