With Manual Transaxle
SYSTEM INSPECTIONWARNING: Fuel line spills and leaks are dangerous. Fuel can ignite and cause serious injuries or death and damage. Fuel can also irritate skin and eyes. To prevent this, always complete the "Fuel Pressure Release Procedure".
1. Install the fuel pressure gauge.
2. Measure the fuel pressure under the following conditions.
3. If the fuel pressure is not within the specification, carry out either Inspection 1 or Inspection 2 as required.
INSPECTION 1
1. Stop the engine.
2. Connect the Special Service Tools (SST)s New Generation Star (NGS) tester to the data link connector-2.
3. Verify that diagnostic trouble code No. P1250 is not displayed. If code No. P1250 is shown, carry out troubleshooting of the code No. P1250.
4. Start the engine and run it at idle.
5. Turn the PRO solenoid valve from OFF to ON by using the "SIMULATION TEST" function and check if the fuel pressure changes.
(1) If the pressure changes, check the following.
^ ECM terminal voltage
^ Intake air temperature signal
^ Closed throttle position switch
(2) If the pressure does not change, do as follows.
I. Stop the engine.
II. Turn the ignition switch to ON.
III. Turn the PRO solenoid valve from OFF to ON by using the "SIMULATION TEST" function and check if the operation sound of the valve is heard.
a. If the operation sound is heard, check the following.
^ Pressure regulator
b. If the operation sound is not heard, check the following.
^ PRC solenoid valve
INSPECTION 2
1. Stop the engine.
2. Connect the SST to the data link connector-2.
3. Verify that diagnostic trouble code No. P1250 is not displayed. If code No. P1250 is shown, carry out troubleshooting of the code No. P1250.
4. By using the "PID/DATA MONITOR AND RECORD" function, verify that the PRC solenoid valve is OFF.
5. If the PRC solenoid valve is ON, check the following.
- ECM terminal voltage
- Engine coolant temperature signal
- Intake air temperature signal
6. Turn the PRO solenoid valve from OFF to ON by using the "SIMULATION TEST" function and check if the operation sound of the valve is heard.
(1) If the operation sound of the valve is heard.
^ Loose or damaged vacuum hose between the pressure regulator, PRO solenoid valve, and intake manifold.
(2) If the operation sound is not heard, check the following.
^ PRO solenoid valve
