P2194
System Too Rich at Higher Load Bank 2
DTC P2194, sometimes indicated as P219400 is an OBD diagnostic trouble code indicating a manufacturer-specific fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing system too rich at higher load bank 2.
The most common reason for a P2194 code is a misfire on one or more cylinders. Other causes can include a leaky fuel injector, a dirty or faulty MAF sensor, or a defective fuel pump.
If you're experiencing a misfire, the first thing you should do is check the spark plugs and replace them if they're worn or damaged. You should also check the ignition coils and replace them if they're defective.
If the MAF sensor is dirty or faulty, you can clean it or replace it. If the fuel pump is defective, you can replace it.
