P0103 OBD-II - Mass Air Flow (MAF) Circuit High Input
This DTC means that there is a problem with the Mass Air Flow High (MAF) sensor or circuit. A more technical description would be that the MAF circuit had higher than expected voltage (air flow). Other MAF sensor circuit DTC trouble codes are P0100, P0101, P0102, and P0104.

A code P0103 may mean that one or more of the following has happened:
- The MAF may be disconnected, or a wiring connection may be bad
- The MAF sensor may be damaged
- The vehicle computer may be faulty (very rare)

Thank you for using Fixya, and have a nice day.

for p0102, you can check here.

press on, enter your security code, if you enter wrong 4 digit code the display is OFF or EEEE, wait 2 hours to enter code again

You turn the disc button I think it is, to get the numbers up you want, then push in to confirm the number you have and then bingo should be on. If you do not have the code give volvo service dept a quick call with your reg and they will fix you up with the code.

you must call the dealer with your vin number and radio serial number. bentley publishers carries these kinds of manuals or ask the dealer when you call them for the code. happy holidays.

Hi, Since you have both codes Fuel system lean and MAF low I would bet money on that you have an intake air leak after the throttle. Check all hoses connected to the intake manifold, gaskets, injectors are put in place etc.

Catalytic converter efficiency.

Hello there. I have a Volvo V70 that I bought recently and it had the same problem. I left the ignition switched on for about two hours and after that time the reading had changed from OFF to Code. I then entered the code and Hey Presto It worked. When I purchased the car it too had no code. I went to a Volvo Dealership, with proof of ownership of the vehicle i.e. Log Book and proof of ID , I used my Passport, and they gave me the radio code.The only dowside was I had to pay them £10 for this code but I feel it was worth it. I suggest you try this too. Good Luck.

TURN ON IGNITION LEAVE PARKED UP FOR ABOUT 1 HOUR WITH IGNITION STILL ON IT WILL THEN CLEAR AND COME UP CODE,THEN ENTER CODE
