OBD 0068 indicates a fault in the MAP throttle position sensor.0068 indicates a fault in the MAP throttle position sensor.
the map sensor is closely related to the throttle position sensor, it is usually located on or close to the throttle body.
The throttle position sensor, map sensor and idle air control valve are all located on the throttle body.
First off it is a throttle body not a carburetor.The item on the rear is the idle air control motor (IAC). The sensor on the driver side is the throttle position sensor (TPS). The sensor on the front is manifold absolute pressure sensor (MAP).First off it is a throttle body not a carburetor.The item on the rear is the idle air control motor (IAC).

Trouble code P1121 means: Throttle Position Sensor A Inconsistent With MAF/MAP Sensor
its either the throttle position sensor or the map sensor.
the map sensor is on the outside of the throttle body.
Assuming you mean the throttle position sensor. The throttle position sensors tells the engine computer when the throttle position has changed, it adjusts fuel flow to match the throttle opening. If the throttle position sensor fails then the engine computer has to depend only on the MAP sensor to define air flow thus how to adjust the fuel flow. I would expect then that response time would be slower than when the throttle position sensor works correctly. On a Chevy Celebrity it might also turn on the check engine light and post either a code 21 or a code 22.
Trouble code P0121 means: Throttle Position Sensor Voltage Does Not Agree With Map Sensor
the map sensor is located on the air intake manifold on the left side under the throttle position sensor on the 2.2 4 cyl. motor.
I had the same problems and it was 3 sensors gone bad. Map sensor, Throttle position sensor and mass airflow sensor. Have those checked out by a reputable mechanic 1st.
on the side of your throttle body dont confuse your map sensor they look the same
