2. If the solenoid does not allow air to pass freely while energized, replace the solenoid with a
new one.
1441−44 MODELS
1. Remove the CANP solenoid.
2. Measure the resistance between the two CANP terminals.
1. If the resistance is between 30−40 ohms, proceed to the Step 3.
2. If the resistance is not between 30−40 ohms, replace the CANP solenoid.
3. Attach a hand−held vacuum pump to the intake manifold vacuum side of the CANP solenoid, then
apply 16 in. Hg (13 kPa) of vacuum to the solenoid.
1. If the solenoid will not hold vacuum for at least 20 seconds replace it with a new one.
2. If the solenoid holds vacuum, proceed to Step 4. Keep the vacuum applied to the solenoid.
4. Using an external voltage source, apply 4−14 DC volts to the CANP solenoid electrical terminals.
1. If the solenoid opens and the vacuum drops, the solenoid is working properly.
2. If the solenoid does not open and the vacuum remains, replace the solenoid with a new one.
