Connect Pressure Gauge to EPC pressure tap.
Start the engine, increase and maintain 1,000 engine RPM and check EPC pressure. See the LINE PRESSURE CHART for specification.
If EPC pressure is not within specification, GO to PINPOINT TEST E to diagnose EPC operation. If EPC operation is OK, see the LINE PRESSURE DIAGNOSIS CHART for line pressure concern causes.
