CONTINUOUSLY VARIABLE TRANSMISSION (DIAGNOSTICS) > Diagnostic Procedure with Diagnostic Trouble Code (DTC)
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.
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.
