Integrated Anti-Theft Alarm Sensor
The electrical sensor built into the latch allows the vehicle to determine the hood’s position.
When the hood is properly closed, the system expects the corresponding sensor state.
When the hood opens, the sensor changes state.
On vehicles equipped with the appropriate factory security functions, this information can be used as part of the anti-theft system.
If someone opens the hood while the security system is armed, the vehicle can recognize that event.
Symptoms of a Bad Ford Fiesta Hood Latch Sensor
A failing hood latch or integrated sensor can potentially cause symptoms such as:
- Hood-open warning when hood is closed
- Intermittent hood-ajar indication
- Factory alarm behaving unexpectedly
- Alarm triggering without an obvious reason
- Security system not properly recognizing hood position
- Hood sensor fault
- Damaged or corroded latch connector
- Mechanical hood-latch problems
Symptoms depend on vehicle equipment and the exact failure.
False Alarm Problems
A defective hood-position sensor can be particularly annoying because the security system may receive incorrect information.
Imagine the vehicle is parked and armed.
The hood is physically closed.
But the sensor intermittently reports:
HOOD OPEN
The security system may interpret that change as an intrusion event.
The result can be an alarm that appears to activate randomly.
Before blaming the entire security system, inspect the hood latch and its electrical connection.
Check the Connector Before Replacing the Latch
Before ordering a replacement, inspect the original latch.
Look for:
- Corrosion
- Water intrusion
- Damaged terminals
- Broken wiring
- Loose connector
- Bent pins
- Physical latch damage
A wiring problem can imitate a failed sensor.
If the vehicle cannot receive the correct signal because a wire is broken, installing a new latch alone will not repair the circuit.
Mechanical Latch Problems
The assembly also performs the much more important job of physically securing the hood.
Replacement may be appropriate if the original latch has:
- Excessive wear
- Corrosion
- Binding
- Physical damage
- Broken mechanism
- Sensor failure
A hood latch is a safety-critical component.
If the hood does not positively latch and remain secured, the vehicle should not be driven until the problem is repaired.
Direct Replacement Design
This D2BZ-16700-B replacement is designed to replace the corresponding factory-style assembly.
That means installation uses the vehicle’s existing:
- Mounting location
- Hood-release mechanism
- Electrical connection
Correct installation and adjustment remain important.
The hood should close securely without requiring excessive force.
Verify Hood Alignment After Installation
After replacing a hood latch, check that the hood:
- Engages the primary latch
- Engages the secondary safety catch
- Releases normally
- Sits correctly when closed
- Does not move excessively
- Does not require excessive slamming
Latch alignment can affect both mechanical operation and hood-position sensing.
Never assume the job is finished simply because the bolts went back in.
Test the Hood Release
Before completely finishing installation, verify that the interior hood-release system works correctly.
Check:
- Hood closes securely.
- Interior release disengages the primary latch.
- Secondary safety catch functions.
- Hood opens normally.
- Hood closes and relatches consistently.
A misadjusted latch or release cable can create a much larger problem later.
Test the Electrical Sensor
After installation, verify that the vehicle correctly recognizes the hood position.
Depending on vehicle equipment and diagnostic-tool capability, this may be checked through:
- Instrument-cluster warning
- Security-system behavior
- Body-control-module live data
- Diagnostic scan tool
A scanner capable of accessing Ford body modules can be particularly useful.
Generic OBD-II Readers May Not Be Enough
A basic engine-code reader is designed primarily around emissions-related powertrain diagnostics.
The hood-position sensor is associated with body/security electronics.
For advanced diagnosis, use a scan tool capable of accessing Ford-specific systems such as the Body Control Module where applicable.
That can allow you to inspect the actual hood-switch status rather than guessing.
Is This an Alarm System?
No.
This product does not add an aftermarket alarm to the Ford Fiesta.
It is a replacement hood latch containing the sensor used by the vehicle’s existing electronics.
It does not include:
- Siren
- Remote controls
- Shock sensor
- GPS tracking
- Starter kill
- Remote start
- Smartphone alerts
The vehicle’s existing security system must already support the relevant hood-monitoring function.

Why Replace the Complete Latch?
When the hood-position sensor is integrated into the latch assembly, replacing the complete assembly can be more practical than attempting to repair the sensor internally.
You restore:
- Mechanical latch function
- Hood-position sensing
- Factory-style electrical connection
in a single assembly.
Made as an OE-Style Replacement
This replacement is manufactured as a direct-replacement component for the corresponding Ford application.
The goal is OE-style:
- Fit
- Function
- Mounting
- Electrical compatibility
We would avoid claiming that an aftermarket replacement is literally OEM unless the manufacturer is actually Ford or an identified OE supplier.
OE replacement and OEM Ford part are not necessarily the same thing.
What’s Included?
Package includes:
1 × Hood Latch Lock Assembly with Integrated Sensor
Reuse or replacement of additional hardware depends on the vehicle and condition of the original components.

Frequently Asked Questions
What does D2BZ-16700-B fit?
This replacement is listed for 2014–2019 Ford Fiesta applications.
Are D2BZ-16700-B and D2BZ16700B the same number?
Yes. The second format simply omits the hyphens.
Does this fit a 2014 Ford Fiesta?
Yes, according to the supplied fitment information.
Does it fit a 2015 Ford Fiesta?
Yes.
Does it fit a 2016 Ford Fiesta?
Yes.
Does it fit a 2017 Ford Fiesta?
Yes.
Does it fit a 2018 Ford Fiesta?
Yes.
Does it fit a 2019 Ford Fiesta?
Yes.
Does the hood latch include a sensor?
Yes. This assembly includes the electrical hood-position/anti-theft sensor.
Can a bad hood latch cause a false alarm?
A faulty hood-position sensor or its wiring can potentially cause the security system to incorrectly detect a hood-opening event on vehicles that monitor the hood.
Can a bad hood latch cause a hood-open warning?
Yes. If the integrated sensor fails or the circuit has a problem, the vehicle may incorrectly report the hood position.
Is this a complete car alarm?
No. It is a replacement hood latch/sensor assembly used by the vehicle’s existing systems.
Is this a genuine Ford OEM part?
Unless the actual product is supplied by Ford or an identified OE manufacturer, it should be described as an OE-style replacement referencing Ford part number D2BZ-16700-B, not as a genuine Ford OEM part.
Do I need a scan tool after installation?
Not necessarily, but a Ford-compatible scan tool with body-module access can help verify hood-switch operation and diagnose related faults.
Is the hood latch safety critical?
Yes. The latch must mechanically secure the hood. Always confirm proper primary and secondary latch operation after installation.
Fix the Latch and the Signal
The hood latch on a modern Fiesta has two jobs.
Job number one:
Keep the hood attached to the front of the car.
Pretty important.
Job number two:
Tell the vehicle whether that hood is actually closed.
When either function starts failing, replacing the complete latch assembly can restore both the mechanical locking mechanism and the electrical hood-position signal.
For a 2014–2019 Ford Fiesta using OE reference D2BZ-16700-B, this replacement provides a straightforward way to replace a worn, damaged or malfunctioning factory-style hood latch and sensor assembly.
Verify the part number.
Check the wiring.
Install and adjust it correctly.
And most importantly, make sure the hood actually stays closed before heading back onto the road.
