Field Trouble,ATM 3rd Hold-TPS(throttle Position Sensor)Hyundai Sonata (NF)

Model: Sonata (NF)	Year model: 2006	Mileage: 94313km
Displacement: 2400cc	Fuel: Gasoline	T/A Auto
N code: Impossible to shift(3rd hold)	C code: poor contact & Short,open circuit.	System: Automatic Transaxle Control system

Subject:ATM 3rd Hold-TPS(Throttle Position Sensor

1) Trouble Condition:

1. Impossible to shift intermittently.
2. Normal shift in Sport mode.

2) Trouble Cause:

1. Abnormal TPS

3) Trouble Diagnosis:

1. Check output speed sensor = Normal
2. Check the TPS: the value between ECM and TCM are different.
   = ECM (Engine Control Module) = 2 percent
   = TCM (Transmission Control Module) = 50 percent
   = The condition of the TPS wiring was Normal
   = The current data for the engine(Before repairing)
   = Current Data after repairing(After repairing)
