DTC Troubleshooting (cont'd)
17. Check for continuity continuity between EVAP
bypass solenoid valve 2P connector terminal No. 2
and body ground.

Wire side of female terminals
Is there continuity?
YES Go to step 18.
NO Repair open in the wire between the EVAP
bypass solenoid valve and the PCM (A3).
18. Turn the ignition switch ON (II).
19. Measure voltage between EVAP bypass solenoid
valve 2P connector terminal No. 1 and body ground.

Is there battery voltage?
YES Replace the EVAP bypass solenoid valve (A)
and the O-rings (B).
NO Repair open in the wire between the EVAP
bypass solenoid valve and No. 6 ECU (PCM)
CRUISE CONTROL (15A) fuse.
20. Plug the upper port (A) of the EVAP two way valve.
21. While monitoring the FTP sensor voltage with the
HDS, or while measuring the voltage between PCM
connector terminals A29 and C18, slowly pump the
vacuum pump until the voltage drops to about
1.5 V.
Does the voltage drop to 1.5 V and hold f or at
least 20 seconds?
YES The EVAP bypass solenoid valve/EVAP two
way valve is OK. Go to step 22.
NO Repair leakage from the EVAP bypass
solenoid valve, EVAP two way valve, FTP sensor, or
O-rings.
