Line Pressure Test

CAUTION: Carry out the line pressure test prior to carrying out the stall speed test. If the 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 in any transaxle range for more than five seconds.

This test verifies that the line pressure is within specification.
1. Connect a pressure gauge to the line pressure tap.
2. Start the engine and check the line pressures.

a All pressures are in PSI and are approximate.

3. If the line pressure is not within specification, check EPC pressure.
4. Connect a pressure gauge to the EPC pressure tap.
5. Start the engine and check the EPC pressure.
6. If the EPC pressure is not within specification, go to Pinpoint Test E to diagnose the EPC operation. If EPC operation is OK, refer to the Line Pressure Diagnosis Chart for line pressure concern causes.
