Test procedure
- 1. Fuel Pressure - Relieve
- 2. Fuel Pressure - Test
NOTE: If you were referred to this procedure from a troubleshooting procedure, test the fuel pressure under the same conditions the malfunction occurred (engine speed, load, throttle position, etc.).
1. Disconnect the quick-connect fitting and attach the fuel pressure gauge set. Check for leaks with the gauge set attached.
2. Start the engine, and let it idle.
- If the engine starts, go to step 3 and read the fuel pressure gauge.
- If the pump does not run and any DTCs are stored, do the DTC troubleshooting - Refer to: CVT System DTC Troubleshooting Index (Except Touring)Fuel and Emissions Systems DTC Troubleshooting Index (Except Touring) .
- If the pump does not run and no DTCs are stored, do the fuel pump circuit troubleshooting .
3. Read the fuel pressure gauge. The pressure should be:390-440 kPa (3.98-4.49 kgf/cm2, 56.6-63.8 psi)
- If the pressure is OK, the test is complete.
- If the pressure is out of specification, replace the fuel pressure regulator and the fuel filter , then recheck the fuel pressure.
