Line Pressure Test

LINE PRESSURE TEST (AF33-5)

^ TOOLS REQUIRED
- J45542 Gauge Bar Adapter
- SA9127E Gauge Bar Set














CAUTION: SET THE PARKING BRAKE AND KEEP BRAKES APPLIED AT ALL TIMES IN ORDER TO PREVENT UNEXPECTED VEHICLE MOTION.

IMPORTANT: The transaxle must be in Park or Neutral, with the vehicle stopped, in order for the Scan tool to be able to command the line pressure lower than normal. This protects transaxle clutches from extremely low pressure in drive or reverse ranges.

Before performing a line pressure check, verify the Line PC Solenoid is receiving the correct electrical signal from the transaxle control module (TCM).
1. Steer front wheels to the left.
2. Raise vehicle.
3. Remove left front splash shield.
4. Remove the B5 fluid pressure test hole plug and install the Gauge Bar Set SA9127E and Gauge Bar Adapter J45542 to the B5 port.
5. Connect a Scan tool.
6. Shift into Park and apply parking brake.
7. Start engine and allow to idle.
8. Select Functional Line PC Solenoid Test from Scan tool Output Controls menu.
9. Increase and decrease Line PC Solenoid Reference Current. Record the corresponding line pressure shown on pressure gauge.
10. Exit the Functional Line PC Solenoid Test on Scan tool.
11. Firmly depress brake pedal, and shift transaxle into Drive. Allow engine to idle.
12. Record the line pressure shown on the pressure gauge.

NOTICE: Do not run the 2450 RPM stall test longer than 5 seconds continuously. Allow 2 minutes between stall tests for the oil to cool. Otherwise, transaxle damage may result.

13. Increase engine speed to 2450 RPM.
14. Record line pressure shown on pressure gauge.
15. Allow engine to idle, and shift transaxle into Reverse.
16. Record line pressure shown on pressure gauge.
17. Increase engine speed to 2450 RPM.
18. Record line pressure shown on pressure gauge.
19. Compare data to the line pressure charts.
