Installation Notes

Before installing the replacement sensor, inspect the air filter, intake tract, connectors, and wiring for dirt, debris, looseness, or damage. Common failure causes include over-voltage, shorted wiring, moisture intrusion, cracked circuit boards, burnt sensing elements, and air intake obstructions. If the engine changes behavior when the unit is lightly tapped, the sensor is faulty and should be replaced.
