Enable Conditions	Case 1	Ignition "ON"
Enable Conditions	Case 2	In normal idle status Target throttle angle < 58% MAF Limp home detected or TPS1 failure detected
Threshold Value	Case 1	TPS2 < 0.1V
Threshold Value	Case 2	TPS2 at idle < 2.0V
Diagnostic Time		50 msec.
Limp-Home		Forced limited power mode: When the DTC is set, the ECM reduces engine torque by 25% of normal value. The ECM uses TPS1 signal to monitor the controlled opening angle of the throttle valve.
