DTC P1121: Throttle Position (TP) Lower Than Excepted

Turn ignition on. Using scan tool, check throttle position. With throttle valve fully open, if TP percentage is 12.2 percent on A/T (12.9 percent on M/T) or more, problem is intermittent, system is functioning properly at this time. If TP percentage is less than 12.2 percent on A/T (12.9 percent on M/T), replace TP sensor.
