DTC P2750 INTERMEDIATE SHAFT SPEED SENSOR "C" CIRCUIT RANGE/PERFORMANCE

DTC detecting condition:

Immediately at fault recognition

Trouble symptom:

• Shifting shock is felt.

• Acceleration is poor during standing start.

• Shift control malfunction

STEP	CHECK	YES	NO

1.CHECK DTC.

Read the DTC using Subaru Select Monitor.

Besides DTC P2750, is any of the DTC P2751, U0122 or U0416 displayed?

Perform the diagnosis according to DTCs other than P2750.

Perform the diagnosis according to DTC P2751. Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P2751 INTERMEDIATE SHAFT SPEED SENSOR "C" CIRCUIT NO SIGNAL">

1. OUTLINE OF DIAGNOSIS

• Detect the malfunction of the secondary speed sensor characteristics.

• Judge as NG if the deviation of vehicle speed between VDC and the secondary speed sensor becomes the predetermined value or more.

2. EXECUTION CONDITION

Secondary Parameters	Execution condition
12 V battery system voltage	≥ 10 V
Vehicle speed (calculated from wheel speed sensor)	≥ 5 MPH

3. DIAGNOSTIC METHOD

If the duration of time while the following conditions are met is longer than the time indicated, judge as NG.

Judgment Value

Malfunction Criteria	Threshold Value
ABS (Vehicle speed (calculated from secondary pulley shaft speed) − Vehicle speed (calculated from wheel speed sensor))	> 10 MPH

Time Needed for Diagnosis: 5 seconds

Malfunction Indicator Light Illumination: Illuminates as soon as a malfunction occurs.
