DTC P2746 INTERMEDIATE SHAFT SPEED SENSOR "B" CIRCUIT RANGE/PERFORMANCE

DTC detecting condition:

Immediately at fault recognition

Trouble symptom:

• Standing start problems

• Shock occurs when engaging the lockup clutch.

• Shock occurs when selecting shift position.

STEP	CHECK	YES	NO

1.CHECK DTC.

Read the DTC using Subaru Select Monitor.

Besides DTC P2746, is DTC P2747 or P2751 displayed?

Perform the diagnosis according to DTCs other than P2746.

Perform the diagnosis according to DTC P2747. Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P2747 INTERMEDIATE SHAFT SPEED SENSOR "B" CIRCUIT NO SIGNAL">

1. OUTLINE OF DIAGNOSIS

Diagnosis 1

• Detect the malfunction of primary speed sensor signal characteristics.

• Judge as NG if the primary speed, compared with the speeds of other parts, is outside the possible range considering the hardware capabilities.

Diagnosis 2

• Detect the malfunction of primary speed sensor signal characteristics.

• Judge as NG if the primary speed exceeds the predetermined value.

2. EXECUTION CONDITION

Secondary Parameters	Execution condition
Diagnosis 1
12 V battery system voltage	≥ 9 V
Transmission range	Drive or Reverse
(Measured turbine shaft speed / Measured secondary pulley shaft speed)	≥ 0.4
	and
	≤ 2.55
Diagnosis 2
12 V battery system voltage	≥ 9 V
Transmission range	Drive or Reverse
(Measured turbine shaft speed / Measured secondary pulley shaft speed)	≥ 0.4
	and
	≤ 2.55

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
Diagnosis 1
(Measured primary pulley shaft speed / Measured secondary pulley shaft speed)	< 0.36
	or
	> 2.80
Diagnosis 2
Measured primary pulley shaft speed	> 7140 rpm

Time Needed for Diagnosis: 5 seconds

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