Frequently Asked Questions
Can a worn door striker cause this code?
Yes. A worn or misaligned striker can prevent the door from closing completely, keeping the door ajar switch from being fully depressed and triggering a false open signal.
How much does a door jamb switch cost?
The switch itself is usually inexpensive, ranging from $5 to $30 for most vehicles. Labor to replace it is typically minimal as well, making this a low-cost repair.
Is this related to the door lock actuator?
No. The door ajar switch and the door lock actuator are separate components. The ajar switch detects open or closed status, while the lock actuator physically locks and unlocks the door.
