5-92 FI SYSTEM DIAGNOSIS
“C49” (P1768) or “C61” (P1656) PAIR CONTROL SOLENOID VALVE
CIRCUIT MALFUNCTION
INSPECTION
Step 1
(When indicating C49/P1768 for #2)
(When indicating C61/P1656 for #1)
1) Turn the ignition switch OFF.
2) Lift up the fuel tank. (#6-3)
3) Check the PAIR control solenoid valve coupler for loose or
poor contacts.
If OK, then measure the PAIR control solenoid valve resis-
tance.
4) Disconnect the PAIR control valve coupler and measure the
resistance between terminals.
$ PAIR valve resistance: 18 – 22
Ω
at 20 – 30 °C (68 – 86 °F)
(Terminal – Terminal)
! 09900-25008: Multi-circuit tester set
% Tester knob indication: Resistance (Ω)
Is the resistance OK?
5) After repairing the trouble, clear the DTC using SDS tool.
(#5-26)
