Recirculation Control Motor Test

2011 Honda CR-V EX, 2.4 RE3, MZJASECTION Recirculation Control Motor Test

NOTE: Before testing the motor, check for HVAC DTCs (see GENERAL TROUBLESHOOTING INFORMATION ).

Disconnect the 7P connector from the recirculation control motor.
NOTE: Incorrectly applying power and ground to the recirculation control motor will damage it. Follow the instructions carefully.
Connect battery power to the terminal No. 1 of the recirculation control motor, and ground the terminal No. 2; the recirculation control motor should run, and stop at Recirculate. If it doesn't, reverse the connections; the recirculation control motor should run, and stop at Fresh. When the recirculation control motor stops running, disconnect battery power immediately.

If the recirculation control motor did not run in step 2, remove it, then check the recirculation control linkage and door for smooth movement.
- If the linkage and door move smoothly, replace the recirculation control motor (see RECIRCULATION CONTROL MOTOR REPLACEMENT ).
- If the linkage or door sticks or binds, repair them as needed.
- If the recirculation control motor runs smoothly, go to step 4.
Measure the resistance between the terminals No. 5 and No. 7 of the recirculation control motor. It should be between 4.2 and 7.8 kΩ.
Reconnect the recirculation control motor 7P connector, then turn the ignition switch to ON (II).
Using the backprobe set, measure the voltage between the terminals No. 3 and No. 7.
Recirculate: Fresh:

About 4.0 V About 1.0 V
If either the resistance or voltage readings are not as specified, replace the recirculation control motor (see RECIRCULATION CONTROL MOTOR REPLACEMENT ).

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

• You smell fuel, burning insulation, or see smoke.
• Brakes feel soft, pull hard to one side, or make grinding noises.
• The engine overheats, stalls repeatedly, or misfires under load.
• You are missing required tools, torque specs, or safe lifting equipment.
• You are not confident in the next step or safety outcome.
