Circuit/System Verification
1. Ignition ON, observe the DTC information with a
scan tool.
2. Record Freeze Frame and Failure Records.
3. Clear DTC's.
4. Operate the vehicle under the conditions observed in
the Failure Records.
5. Observe the DTC information with the scan tool.
Automatic Transmission:
Circuit/System Testing
1. Ignition OFF, disconnect the 4-way Speed Sensor
Connector (C3) at the TCM.
2. Ignition ON, Test for 9-12 volts between the high
signal circuit, TCM terminal C3-3 (ISS) or C3-2
(OSS) and low signal circuit, TCM terminal C3-4
(ISS) or C3-1 (OSS).
➢ If not within the specified range, replace the TCM.
Refer to "Transmission Control Module Removal"
and "Transmission Control Module Installation"
procedure.
3. If the circuits test normal, test or replace the speed
sensor.
Component Testing
1. Test the speed sensor wiring. There should not be
an open, short to ground, or a short together
condition.
➢ If one of the above conditions is found, repair the
circuit.
2. If all circuits test normal, replace the sensor.

DTC Descriptor
DTC P0730: Incorrect Gear Ratio
Circuit/System Description
The transmission control module (TCM) calculates the
actual gear ratio based on input speed sensor (ISS) and
output speed sensor (OSS) data. The actual gear ratio is
compared to the expected gear ratio for each
commanded gear.
If the TCM detects an incorrect 1st gear ratio while
decelerating in 1st gear, DTC P0730 sets.
5A-123
