On-Vehicle Inspection
ON-VEHICLE INSPECTION1. CHECK FUEL PUMP OPERATION AND FUEL LEAK
a. When using the hand-held tester
1. Connect the hand-held tester to the DLC3.
2. Turn the ignition switch ON and hand-held tester main switch ON.
NOTE: Do not start the engine.
3. Select the ACTIVE TEST mode on the hand-held tester.
4. Please refer to the hand-held tester operator's manual for further details.
b. When not using hand-held tester
1. Remove the circuit opening relay.
2. Using a service wire, connect terminals FP and +B of the relay block.
NOTE: Pay due attention to the terminal connecting position to avoid a malfunction.
3. Turn the ignition switch ON, and check that the fuel pump operates.
NOTE: Do not start the engine.
c. Check that there are no fuel leaks after doing maintenance to the fuel system.
d. Turn the ignition switch OFF.
e. Disconnect the hand-held tester from the DLC3.
2. CHECK FUEL PRESSURE
a. Prepare for inspection.
1. Prepare a new fuel tube, and take out the fuel tube connector from the tube.
HINT: Part No. 23801-31070
b. Prevent gasoline from spilling out.
c. Disconnect the EFI fuel pipe clamp.
d. Disconnect the fuel pipe No. 1 from the fuel main tube.
e. Install SST (pressure gauge) as shown in the illustration by using the SSTs and a fuel tube connector.
SST 09268-41047 (90467-13001, 95336-08070), 09268-45014 (09268-41200, 09268-41220, 09268-41250, 90467-13001)
f. Wipe off any splattered gasoline.
g. Start the engine.
h. Measure the fuel pressure at idle.
Fuel pressure:
281 - 287 kPa (2.87 - 2.93 kgf.sq.cm, 40.8 - 41.7 psi)
i. Stop the engine.
j. Check that the fuel pressure remains as specified for 5 minutes after the engine has stopped.
Fuel pressure:
147 kPa (1.5 kgf.sq.cm, 21 psi) or more
If pressure is not as specified, check the fuel pump, pressure regulator and/or injectors.
k. After checking the fuel pressure, disconnect the negative (-) terminal cable from the battery carefully, remove the SST and fuel tube connector to prevent gasoline from the splashing.
l. Reconnect the fuel tube to fuel main tube.
m. Install the EFI fuel pipe clamp.
n. Check for fuel leak.
