Jeep cherokee’s mileage blinking can be an annoying and confusing issue for many owners. One of the possible causes of this malfunction is dirty sensors. In this section, we’ll explain how this happens, how to recognize the symptoms, and how to clean the sensors.
Explanation Of How Dirty Sensors Can Cause The Mileage To Blink
Here’s how the dirty sensors can affect the mileage signal that appears on your jeep’s dashboard:
- Modern vehicles typically have multiple sensors that monitor various engine and driving parameters, such as the air/fuel ratio, the oxygen levels, the throttle position, the temperature, and the speed.
- Some of these sensors contribute to calculating the distance and fuel consumption, which are the basis for the mileage information.
- If these sensors become coated with dirt, dust, or debris, their performance may degrade, making them less accurate or responsive.
- For example, a faulty speed sensor may misinterpret the wheel rotation and cause the mileage to blink as if the car is driving erratically, even when it’s not.
Symptoms Of Dirty Sensors
If your jeep cherokee’s mileage is blinking and you suspect that the sensors might be dirty, you may notice one or more of the following symptoms:
- Inconsistent or fluctuating mileage display
- Incorrect mileage readings that don’t match the actual distance traveled or fuel consumption
- Coded error messages related to the sensors or the emissions system
- Poor engine performance, such as rough idling, stalling, or low power output
- Increased fuel consumption or emissions
How To Clean Sensors
Fortunately, cleaning the sensors that may cause the mileage to blink is not a complicated task, and you can often do it yourself with some basic tools and supplies.
- Locate the relevant sensors. The owner’s manual or a repair guide can help you identify which sensors are involved and where they are situated, usually in the engine compartment or near the wheels.
- Remove any covers or brackets that shield the sensors, using the appropriate screwdrivers or sockets.
- Inspect the sensors for signs of buildup or corrosion, such as discoloration, rust, or caked-on dirt. Be careful not to damage any fragile components, and avoid touching the wires or connectors unnecessarily.
- Clean the sensors with a soft, lint-free cloth or brush and a suitable cleaning solution, such as electrical contact cleaner or rubbing alcohol. Avoid using abrasive or corrosive materials that may scratch or corrode the sensors.
- Reinstall the sensors and the covers or brackets, and make sure they are securely fastened. Test drive the jeep cherokee for a while to see if the mileage blinking issue persists or if it’s been resolved.
By keeping the sensors clean and functional, you can prevent or solve many problems related to the mileage blinking on your jeep cherokee. If you’re not confident about doing the cleaning yourself, or if you suspect that the sensors may be damaged or faulty, consult a professional mechanic or dealer for further advice and assistance.

Symptoms Of Fuel Sensor Issues
Here are some common symptoms to look out for that could indicate fuel sensor issues:
- Blinking mileage
- Inaccurate fuel gauge readings
- Random changes in fuel levels or fuel gauge readings
- Engine misfires
- Difficulty starting the engine
How To Diagnose And Replace Fuel Sensors
If you suspect that the fuel sensor is the issue behind your blinking mileage, follow these steps:
- Check the fuel gauge to ensure it’s working correctly.
- Use an obd-ii scanner to check for codes relating to the fuel system.
- Inspect the wiring and connections to the fuel sensor for any damage or looseness.
- If there are no visible issues with the wiring, replace the fuel sensor.
Replacing the fuel sensor in your jeep cherokee involves draining the fuel tank, removing the old sensor and installing the new one, and then reconnecting the fuel lines and electrical connections. It’s essential to have a professional mechanic or certified technician perform this procedure to avoid further damage or complications.
If you’re experiencing a blinking mileage on your jeep cherokee, it’s essential to have it checked out to determine the cause of the issue.
