P0717

Diagnostic Chart:

Wiring Diagram - Turbine Shaft Speed Sensor:

DTC P0717 indicates no turbine speed signal pulses are present on circuit 1230 at the PCM. Transaxle turbine shaft speed values are provided by the turbine shaft speed (TSS) sensor. The sensor is a permanent magnet (PM) generator mounted near the pressure filter on the transaxle case. The PM generator produces a pulsing voltage whenever turbine shaft speed is above 250 rpm. These pulses occur eight times per each turbine shaft revolution and are translated to provide turbine shaft speed in rpm.

DTC PARAMETERS

DTC P0717 is set when the PCM has detected the following conditions for more than two seconds.

^ Turbine speed is zero.

^ Vehicle speed is greater than 10 km/h (6 mph).

^ Engine speed greater than 3472 rpm.

^ Condition exists for 2 seconds.

TEST DESCRIPTION

Numbered steps below refer to numbered steps on chart.

1. This step verifies the problem is still present.

2. This test indicates if problem is PCM or a wiring/sensor problem.

3. An open, ground or a short to voltage in circuits 1230 or 1231 will cause DTC P0717 to set. This step indicates which circuit is faulty.

4. An open or shorted sensor will set DTC P0717. This test indicates if problem is a wiring problem or a faulty sensor.

REPAIR VERIFICATION

Monitor DTC menu "Code Status" for "Pass Since Code Clear" and "Pass This Ignition Cycle." When both have passed, repair is verified.

Criteria for pass:

^ Turbine shaft speed is greater than 1232 rpm for two seconds.

DIAGNOSTIC AIDS

When attempting to diagnose an intermittent problem use the Scan tool* to review supplemental diagnostic information. The supplemental data can be used to duplicate a problem.

* Select MALF History and DTC status from DTC menu of Scan tool.

Check the tightness of the female terminal grip with a spare male terminal.

Check wire routing for possible chafed wires.
