DTC DETECTION LOGIC
DTC | Trouble diagnosis name | DTC detection condition | Possible causes |
P0962 | Pressure Control Solenoid "A" Control Circuit Low | The following diagnosis conditions
are met, and the current
monitor reading of the TCM line
pressure solenoid valve is 200
mA or less continuously for 0.5
seconds or more. - Diagnosis condition - Solenoid valve output current: 750 mA or more - GND short circuit diagnosis occurs in the solenoid valve drive circuit. - TCM power supply voltage: 10 V < TCM power supply voltage < 16 V |
- Harness or connector
(Short circuit to ground in the
line pressure solenoid valve
circuit) - Line pressure solenoid valve |
DTC CONFIRMATION PROCEDURE
1.PREPARATION BEFORE WORK
If another "DTC CONFIRMATION PROCEDURE" occurs just before, turn ignition switch OFF and wait for at least 10 seconds, then perform the next test.
>> GO TO 2.
2.CHECK DTC DETECTION
Selector lever : N position
Engine speed : Idle speed
3. Check the first trip DTC.
Is "P0962" detected?
YES >> Go to TM, "Diagn
Diagnosis Procedure
1.CHECK CIRCUIT BETWEEN TCM AND A/T UNIT
Is the check result normal?
YES >> GO TO 2.
NO >> Repair or replace the malfunctioning parts.
2.CHECK LINE PRESSURE SOLENOID VALVE
Check the line pressure solenoid valve. Refer to TM, "Component Inspection (Line Pressure Solenoid Valve)".
Is the check result normal?
YES >> Check intermittent incident. Refer to GI, "Intermittent Incident".
NO >> Repair or replace the malfunctioning parts.
Component Inspection (Line Pressure Solenoid Valve)
1.CHECK LINE PRESSURE SOLENOID VALVE
Check the resistance between the A/T unit connector and ground.
Is the check result normal?
YES >> INSPECTION END
NO >> There is a malfunction of line pressure solenoid valve. Replace the transaxle assembly. Refer to TM, "Removal and Installation".

P0506 ISC system
Description
The ECM controls the engine idle speed to a specified level through the fine
adjustment of the air, which is let
into the intake manifold, by operating the electric throttle control actuator.
The operating of the throttle valve is
varied to allow for optimum control of the engine ...
