P0100/P0199 OBD-II TROUBLE CODES

Trouble codes P0100 through P0199 typically indicate a malfunction of an emission sensor/s responsible for collecting data used in determining correct air to fuel ratio. Optimum air/fuel mixture is needed, as well as accurate ignition timing, in order to produce complete and efficient fuel combustion.

These emissions sensors are responsible for sending vital data allowing the vehicle's ECU (engine control unit) to determine how much fuel to present to the intake air. These codes are generic and will apply to all makes and models of vehicles 1996 and newer.

Bank 1 and Bank 2 describe the location of the component in reference to the left or right side of the engine. Bank 1 is whichever side cylinder number 1 is located. It could be the left side (driver side) or right. Bank 2 is the other side.

Sensor 1 indicates the component is located before the catalytic converter. Sensor 2 indicates the component is located after the catalytic converter.
