Important: This test should only be performed at a normal operating fluid temperature of 50-80°C (122-176°F).
Caution: For the following four steps, procedures for testing line pressure at idle and stall speeds, the brake pedal must be fully pressed throughout the measurement procedure. Failure to do so could result in personal injury and/or property damage.
Notice: DO NOT run engine at stall speed for more than five seconds continuously or engine oil and transaxle fluid temperatures may become excessively high.
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
Tighten
Tighten the line pressure tap bolt to 9 N·m (80 lb in).
Tighten
Tighten the splash shield bolts to 5 N·m (44 lb in).
Compare the line pressure test results with the Line Pressure Results in the following table. If the line pressure is not as specified, refer to the Line Pressure Test Diagnosis for further evaluation.
Engine Running at | R Range Line Pressure | D, 2, L Range Line Pressure |
---|---|---|
Idle Speed (650-750 RPM) | 530-706 kPa (77.9-102.4 psi | 363-422 kPa (52.6-61.2 psi) |
Stall Speed (2150-2450 RPM) | 5.0-7.0 kg/cm² (71.1-99.5 psi) | 902-1049 kPa (130.8-152.0 psi) |
