Line Pressure Test: Notes
CAUTION:
Carry out the Line Pressure Test before carrying out the Stall Speed Test. If line pressure is low at stall, do not carry out the Stall Speed Test or further transaxle damage will occur. Do not maintain wide open throttle (WOT) in any gear range for more than five seconds.
NOTE:
Certain sensor failures may cause high PC, FMEM (Failure Mode Effect Management) actions. Make sure that self test and electrical repairs have been carried out, or test results may be incorrect.
This test verifies that the line pressure is within specification.
- Connect the pressure gauge to the line pressure tap.
- Start the engine and check the line pressures. Refer to the following LINE PRESSURE CHART to determine if line pressure is within specification.
- If line pressure is not within specification, refer to the LINE PRESSURE DIAGNOSIS CHART for line pressure concern causes.
