P0717

DTC P0717: Input shaft 1 (odd number gear axle) speed sensor system (Output current low range out)

CAUTION:

- If there is any problem in the CAN bus lines, an incorrect diagnostic trouble code may be set. Prior to this diagnosis, diagnose the CAN bus lines.
- Whenever the ECU is replaced, ensure that the CAN bus lines are normal.

DIAGNOSTIC FUNCTION

TC-SST-ECU checks that the input shaft 1 (odd number gear axle) speed sensor is normal.

DESCRIPTIONS OF MONITOR METHODS

The output of the input shaft 1 (odd number gear axle) speed sensor is determined to be too low.

MONITOR EXECUTION

- Continuous

MONITOR EXECUTION CONDITIONS (OTHER MONITOR AND SENSOR)

Other Monitor (There is no temporary DTC stored in memory for the item monitored below)

- P0715: Input shaft 1 (odd number gear axle) speed sensor system (Output high range out)
- P0716: Input shaft 1 (odd number gear axle) speed sensor system (Poor performance)
- P2766: Input shaft 2 (even number gear axle) speed sensor system (Poor performance)
Sensor (The sensor below is determined to be normal)

- Input shaft 2 (even number gear axle) speed sensor

LOGIC FLOW CHARTS (Monitor Sequence)





DTC SET CONDITIONS

Check Conditions

- Voltage of battery: 8 V or more.
- Voltage of battery: 16.5 V or less.
- Time after engine start: 1.5 seconds or more.
JUDGMENT CRITERIA

- Sensor current: 4 mA or less. (500 millisecond)

OBD-II DRIVE CYCLE PATTERN

The sensor current remains 4 mA or more for 500 milliseconds.

PROBABLE CAUSES

- Malfunction of TC-SST-ECU
- Malfunction of input shaft 1 speed sensor

DIAGNOSTIC PROCEDURE

Required Special Tools:

- MB991958 Scan Tool (M.U.T.-III Sub Assembly)
- MB991824: Vehicle Communication Interface (V.C.I.)
- MB991827 M.U.T.-III USB Cable
- MB991910 M.U.T.-III Main Harness A

STEP 1. Scan tool CAN bus diagnostics

Using scan tool MB991958, diagnose the CAN bus lines.

Q. Is the check result normal?

YES Go to Step 2.
NO Repair the CAN bus lines. CAN Bus Diagnostics Chart.) After repairing the CAN bus line, go to Step 2.
STEP 2. Check whether the DTC is reset.

After 5 or more seconds have passed with the engine idle status, check that the DTC is reset.

Q. Is DTC No. P0717 set?

YES Replace the transaxle assembly. (Refer to Removal and Replacement.)
NO Intermittent malfunction. How to Cope With Intermittent Malfunctions.)
