أخي العزيز يوجد موقع اسمه - www.crecorder.com - خاص بتحليل الأكواد
وقد وجدت من خلاله أن الكود الخاص بك يعني ما يلي :

DTCs definition: Incorrect Gear Ratio

Detail description: DTC P0730

P0730-Incorrect Gear Ratio

Circuit Description

The powertrain control module (PCM) calculates the gear ratio based on the automatic
transmission input shaft speed sensor (AT ISS) and output shaft speed sensor (AT OSS) readings. The
PCM compares the known transmission gear ratio to the calculated ratio for the selected gear ranges.
Refer to Range Reference . If the PCM detects an incorrect transmission gear ratio, DTC P0730 sets.
DTC P0730 is a type C DTC.

Conditions for Running the DTC

No MAP sensor DTCs P0106, P0107, or P0108.
No TP sensor DTCs P0121, P0122, or P0123.
No VSS DTCs P0502 or P0503.
No ISS DTCs P0716 or P0717.
No TFP manual valve position switch DTC P1810.
No 4WD low DTC P2771.
The engine is running longer than 7 seconds.
The system voltage is 8-18 volts.
The vehicle speed is greater than 8 km/h (5 mph).
The throttle angle is greater than 15 percent.
The TFT is greater than 20?C (68?F).
No gear range change for greater than 6 seconds.
The engine torque must be between 108 N.m (80 lb ft) and :
o 6.0L: 576 N.m (425 lb ft)
o 8.1L: 881 N.m (650 lb ft)
The engine is running for 7 seconds.
The transfer ratio is 0.95-1.05.

Conditions for Setting the DTC

The following conditions are met for 10 seconds.
The Gear Ratio is one of the following:
o Greater than 2.51 or less than 2.43
o Greater than 1.51 or less than 1.44
o Greater than 1.03 or less than 0.97
o Greater than 2.12 or less than 2.05
Action Taken When the DTC Sets

The PCM does not illuminate the malfunction indicator lamp (MIL).
The PCM commands maximum line pressure.
The PCM freezes shift adapts.
The PCM records the operating conditions when the Conditions for Setting the
DTC are met. The PCM stores this information as Failure Records.
The PCM stores DTC P0730 in PCM history.

Conditions for Clearing the DTC

A scan tool clears the DTC from PCM history.
The PCM clears the DTC from PCM history if the vehicle completes 40 warm-up
cycles without a non-emission related diagnostic fault occurring.
The PCM cancels the DTC default actions when the fault no longer exists and the
ignition switch is OFF long enough in order to power down the PCM.

Possible Cause:

Wiring
TR sensor/switch
shift solenoids
transmission mechanical fault
