FI SYSTEM 5-73
“C49” (P1656) PAIR CONTROL SOLENOID VALVE CIRCUIT MALFUNCTION
INSPECTION
Step 1
1) Turn the ignition switch OFF.
2) Check the PAIR control solenoid valve coupler for loose or
poor contacts.
If OK, then measure the PAIR control solenoid valve resis-
tance.
3) Disconnect the PAIR control solenoid valve coupler.
4) Measure the resistance between Black and Black wire termi-
nals.

PAIR valve resistance:
20 – 24
Ω at 20 – 30 °C (68 – 86 °F)
(Black – Black)
 09900-25008: Multi-circuit tester set
 Tester knob indication: Resistance (Ω)
5) If OK, then check the continuity between each terminal and
ground.
 PAIR valve resistance: ∞ Ω (Infinity)
(Terminal – Ground)
 Tester knob indication: Resistance (Ω)
Is the resistance OK?
6) After repairing the trouble, clear the DTC using SDS tool.
