P0099

DTC P0099, sometimes indicated as P009900 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing intake air temperature sensor 2 circuit intermittent/erratic bank 1.

The code P0099 is set when the Intake Air Temperature Sensor 2 circuit intermittently or erratically reports a higher than normal temperature. This could be caused by a faulty sensor, a wiring issue, or a problem with the ECM.
If you are experiencing this issue, you should have the vehicle inspected by a qualified technician to determine the cause.
