Description
FLUID LEVEL SENSOR
Part Number: FN9267001C
Direct replacement (cross ref) for N9267001.
Product Overview
The FN9267001C fluid level sensor monitors fluid levels and sends information to the truck’s control system so the driver or technician knows when levels are low or need attention. On commercial trucks, fluid monitoring is important because running low on essential fluids can quickly turn into a bigger mechanical problem.
This replacement sensor replaces OEM part N9267001 and is designed for compatible Peterbilt applications.
What the Part Does
The fluid level sensor measures the amount of fluid in the system and communicates that information to the vehicle’s monitoring system. Depending on the application, this helps track whether the fluid level is within the correct range.
The sensor works quietly in the background, but it plays an important role in preventing problems. Accurate fluid information allows drivers and technicians to catch low levels before they lead to overheating, component wear, or system failures.
Common Problems This Part Solves
A faulty fluid level sensor can create several issues that are easy to mistake for other problems. Common signs include:
- Incorrect fluid level warnings
- Warning lights appearing when fluid levels are normal
- No warning when fluid levels are actually low
- Inconsistent readings between inspections
- Difficulty diagnosing fluid-related issues
Sometimes the problem is not the fluid itself but the sensor sending bad information.
Why Replacement Matters
A bad fluid level sensor may seem like a small issue, but inaccurate information can lead to missed maintenance problems. If a driver does not receive the correct warning, a low fluid condition can continue longer than it should.
For fleet trucks, reliable sensors help prevent avoidable breakdowns and make routine inspections easier. Technicians can spend less time chasing false warnings and more time addressing actual maintenance needs.
Compatibility and Fitment
This fluid level sensor replaces OEM part N9267001. Before ordering, verify the original part number and application to confirm proper fitment. Sensors can vary depending on truck configuration and system requirements.
Installation and Service Notes
To install it, you need to remove the existing sensor and install the replacement in the correct location. Electrical connections should be inspected before installation to make sure there are no damaged wires, corrosion or loose connections affecting performance.
Related Part: Temperature Sensor – FQ211002C: Both sensors provide important information to the truck’s monitoring systems, so technicians often inspect related sensors when diagnosing warning lights or inaccurate readings.
Use Case
This fluid level sensor is commonly used in fleet maintenance, repair shops, and routine service work where accurate fluid monitoring is important. Keeping sensors in good condition helps drivers avoid surprises on the road and helps maintenance teams identify problems earlier.

FAQs
Q1: How do I know if my fluid level sensor is failing?
A: Common signs include incorrect warning messages, inaccurate readings, or a sensor that does not respond properly when fluid levels change.
Q2: Can a bad sensor damage the truck?
A: The sensor itself usually does not cause mechanical damage, but incorrect readings can allow fluid problems to go unnoticed. Catching low levels early helps protect important truck components.
Q3: Are fluid level sensors difficult to replace?
A: Replacement is usually straightforward for an experienced technician, but proper installation and checking the electrical connection are important for accurate operation.
Q4: Should wiring be inspected when replacing the sensor?
A: Damaged wiring, corrosion, or loose connections can create symptoms similar to a bad sensor.
Q5: How often should a fluid level sensor be replaced?
A: There is no fixed replacement interval. Sensors are usually replaced when they fail.
