Hello - this DTC indicates an issue with the MAP sensor. You can replace this rather easily and any major auto parts store can read this code, clear this code and also carry the part you need.
Thanks for using FixYa!

hi this is showing fuel trim bank 1 malfunction, this could be caused by the following things, intake leak, AIR system, fuel pressure/pump, injector/s EVAP canister purge valve, or HO2S ( air fuel mix incorrect) if it starts and runs fine, i do not think it will be fuel pump, or the injectors as this would make it run rough or even not start at all, if it was an intake leak, you would be suffering from high rev's when you start the car and would take a long time for the rev's to come down, so really, that just leaves the HO2S (sensor/s) these are located one on the exhaust manifold ( from engine follow exhaust manifold you will come to a things sticking out with some wires on) this is HO2S sensor bank 1, or if you look under the car on the exhaust, just past the catalytic converter you will see the same thing, this is HO2S sensor bank 2, it may be either of these, but i possibly would go for the first one, EVAP..it could be, if you have an air leak on it, the EVAP can be found under the hood/bonnet, at the front on the right hand side as you look into the engine/motor bay just in front of the screen was bottle...hope this helps

The Engine and Automatic Transmission (not applicable to manual transmissions) in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM. Also always check fuel pressure for correct spec for your make and engine type.

Testimonial: "Yes this was helpful had the computor read and the diagnostic testing and shows the problem as a servo inside the valve body - $1550 parts and labour to fix. That hurts still has to be done as no good the way it is."
