This bulletin updates TSB 01-40-005 to add additional DTC code information.
DESCRIPTION:
An improperly functioning input speed sensor or output speed sensor may result in the
following four conditions:
1. “Check Engine” light on
2. Harsh P-R or P-D engagement
shock
3. Transaxle accelerates in 1st gear to
approximately 5000 rpm, then
shifts into 3rd gear “fail-safe”
4. Diagnostic trouble codes shown on
Page 2
REPAIR PROCEDURE:
1. Using a Hi-Scan Pro, check for DTCs in both the “Engine” and “Automatic
Transaxle” menus. Record the DTC and description.
2. From the Hi-Scan Pro, select:
• “Hyundai Diagnosis” menu
• Vehicle
• “Auto Transaxle” menu
• “Current Data”
• “Input speed sensor” and “output speed sensor”. While driving the vehicle, if both
input and output speed sensors show:
• Continuous output, go to Step 6 (NOTE: This test indicates the harness does
not currently have an open or short circuit)
• No output or intermittent output, go to Step 3

3. Check the wiring harness visually for any damage.
4. Check the connectors at the input and output speed sensor and PCM/TCM for bent
pins or pins not fully inserted into the connector. Repair or replace as necessary.
5. Follow the directions in the “Wire Harness Repair Kit”, P/N TRK00A, and check the
harness pin tension for the connectors to the input and output speed sensors and
PCM/TCM. Repair or replace as necessary.
6. Follow the repair procedure below (NOTE: This step is necessary because the
sensor may have an intermittent signal at high temperature or vibration):
DTC DESCRIPTION REPAIR PROCEDURE
P0715 Input speed sensor - no signal
Replace input speed sensor
P0717 Input speed sensor - no signal
P0720 Output speed sensor range/performance
P0721 Output speed sensor range/performance Replace output speed sensor
P0722 Output speed sensor - no signal
P0700,
TCM MIL request to ECM Erase code
P1529
NOTE: Use an air nozzle to remove any debris around the sensor. Carefully
clean the area where the sensor mounts before reinstalling the sensor.
7. Drive the vehicle for at least two key-on to key-off driving cycles. If the codes:
• Do not set again, return the vehicle to the customer
• Set again, go to step 8
8. Refer to the appropriate ETM and use a DVOM to check the resistance of the wiring
between the TCM and the input sensor and output sensor (connect a small T-pin to
the DVOM when probing the connector to avoid damage). If the resistance is:
• More than 1 ohm, repair or replace the wiring harness
• Less than 1 ohm, go to Step 9
9. Replace the transaxle control module (TCM) or powertrain control module (PCM).
