DETECTED CONDITION | POSSIBLE CAUSE |
PAIR control solenoid valve voltage is not input in ECM. | • PAIR control solenoid valve circuit open or short. • PAIR control solenoid valve malfunction. • ECM malfunction. |
Inspection
Step 1
1) Remove the fuel tank. (5-7)
2) Turn the ignition switch OFF.
3) Check the PAIR control solenoid valve coupler for loose or poor contacts. If OK, then measure the PAIR control solenoid valve resistance.

4) Remove the air cleaner box. (5-15)
5) Disconnect the PAIR control solenoid valve coupler and measure the resistance between terminals.

- PAIR control solenoid valve resistance: 20-24 Ω at 20°C/68°F
- 09900-25008: Multi circuit tester set
- Tester knob indication: Resistance (Ω)
Is the resistance OK?
YES | Go to Step 2 |
NO | • Loose or poor contacts on the ECM coupler. • Replace the PAIR control solenoid valve with a new one. |
Step 2
1) Connect the PAIR control solenoid valve coupler.
2) Turn the ignition switch ON.
3) Insert the needle pointed probes to the PAIR control solenoid valve coupler.
4) Measure the voltage at the wire side coupler between Brown wire and ground.

- PAIR control solenoid valve voltage: Battery voltage ((+) Brown - (-) Ground)
- 09900-25008: Multi circuit tester set
- 09900-25009: Needle pointed probe set
- Tester knob indication: Voltage (⎓)
Is the voltage OK?
YES | • Brown wire open or shorted to ground, or (7) connection. • If wire and connection are OK, intermittent trouble or faulty ECM. • Recheck each terminal and wire harness for open circuit and poor connection. |
NO | Open or short circuit in the Brown wire. |
