Test Procedure

WARNING: This page is about a different car, the 2002 Mazda Millenia and 2001 Mazda Millenia. However, it is still accessible from the selected car via links, so may be relevant.
  1. Remove square head plug. Connect Oil Pressure Gauge Set (49-0379-400B), Oil Pressure Gauge (49-B019-901) and Adapter (49-H019-002) to line pressure inspection port. Start engine. Shift gearshift lever to "D" position and read line pressure at idle.
  2. Depress accelerator fully and read line pressure as soon as RPM becomes constant, then release accelerator pedal. Shift gearshift lever to "N" position and idle engine for at least one minute, to cool fluid.
  3. Read line pressure at idle and stall speeds for each gear position in the same manner. For stall speed pressure test, replace oil pressure gauge with Oil Pressure Gauge (49-B019-902). Shift gearshift lever to "P" position.
  4. Turn engine off. Remove oil pressure gauge set, oil pressure gauge and adapter. Install NEW square head plug in line pressure inspection port. Tighten plug to 44-87 INCH lbs. (5.0-9.8 N.m). Ensure pressures are within specification. See HYDRAULIC PRESSURE SPECIFICATIONS . If pressures are not to specification, diagnose as necessary. See HYDRAULIC PRESSURE TEST RESULTS  table.
