TM-130 < BASIC INSPECTION > [4AT: RE4F03C] LINE PRESSURE TEST LINE PRESSURE TEST Work Procedure INFOID:0000000009267880 INSPECTION 1. Inspect the amount of engine oil. Replenish the engine oil if necessary. Refer to . 2. Drive for about 10 minutes to warm up the vehicle so that the A/T fluid temperature is to 50 to 80 °C (122 to 176 °F). 3. Inspect the amount of ATF. Replenish if necessary. Refer to . 4. Remove fluid pressure detection plug. 5. Install the joint pipe adapter [SST: KV31103600 ( — )], adapter [SST: 25054000 (J-25695-4)], and oil pressure gauge set (commercial service tool). NOTE: When using oil pressure gauge, be sure to use O-ring attached to fluid pressure detection plug. 6. Securely engage parking brake so that the tires do not turn. CAUTION: Keep brake pedal pressed all the way down during measurement. 9. Install O-rig to fluid pressure detection plug. CAUTION: • Do not reuse O-ring. • Apply ATF to O-ring. 10. Install fluid pressure detection plug. JUDGMENT 1 : “D” position fluid pressure detection plug 2 : “R” position fluid pressure detection plug Line pressure : 7.4 N·m (1.70 lb-m, 66 in-lb) JSDIA2020ZZ Judgment Possible cause Idle speed Low for all positions Possible causes include malfunctions in the pressure supply system and low oil pump output. ⇒ oil pump ⇒ pressure regulator valve passage oil leak • Engine idle speed too low Only low for a specific Possible causes include an oil pressure leak in a passage or device related to the position after High Possible causes include a sensor malfunction or malfunction in the line pressure adjustment |
