Line Pressure Solenoid Valve Output Duty

Inspection




1. Connect the (+) terminal of a dwell meter to terminal 1F (line pressure solenoid valve) and terminal 1H (dropping resistor) of the powertrain control module (transmission). Set the dwell meter selector to the 4 cylinder position.
2. Turn the ignition switch to ON.

Dwell Angle/Duty Ratio Relationship:

3. Depress and release the accelerator pedal, and verify the OFF duty ratio by using the dwell meter.




4. Depress the accelerator pedal slowly and verify the duty ratio changes as shown in the graph.
5. If not as specified, check the following:
- Powertrain control module (transmission)
- Dropping resistor
- Line pressure solenoid
