Code B2298 RAM Description
The B2298 diagnostic trouble code (DTC) specifically refers to the Rain Sensor Over Temperature. This code is typically associated with vehicles equipped with rain-sensing windshield wipers, which use a sensor to detect moisture on the windshield and automatically activate the wipers. When the sensor detects temperatures that are too high, it triggers the B2298 code to indicate an over-temperature condition.
Common Causes of B2298 RAM
- Malfunctioning rain sensor
- Faulty temperature sensor within the rain sensor assembly
- Wiring issues, such as a short or open circuit
- Electrical system problems
- Environmental factors, such as exposure to extreme heat
Symptoms of B2298 RAM
- Inoperative rain-sensing windshield wipers
- Wipers activating randomly or at incorrect times
- Wipers operating continuously, even in dry conditions
- Malfunction indicator light (MIL) or check engine light illuminated on the dashboard
How to Fix B2298 RAM
- Begin by visually inspecting the rain sensor and associated wiring for any visible damage or signs of wear.
- Use a multimeter to test the resistance of the temperature sensor within the rain sensor assembly to determine if it is functioning correctly.
- Check the vehicle's electrical system for any faults or issues that may be affecting the rain sensor operation.
- If necessary, replace the rain sensor assembly or temperature sensor to resolve the over-temperature condition.
- Clear the DTC and perform a test drive to ensure that the rain sensor system is functioning properly.
Cost to Fix B2298 RAM
The cost of repairing the Rain Sensor Over Temperature issue can vary depending on the specific cause of the code and the parts and labor required for the repair. In general, replacing the rain sensor assembly or temperature sensor can range from $150 to $300, including parts and labor. However, additional diagnostic time and potential wiring repairs may increase the overall cost.

Frequently Asked Questions about B2298 RAM Code
1. What does the OBDII code B2298 RAM mean?
B2298 in a RAM vehicle indicates "Rain Sensor Over Temperature," which suggests an issue with the rain sensor detecting an excessively high temperature.
2. What are the common symptoms of a B2298 code?
Symptoms may include malfunctioning of the rain-sensing wipers, a warning light on the dashboard, or the wipers not activating automatically during rain.
3. What causes the B2298 code to appear?
Common causes include a faulty rain sensor, overheating due to electrical issues, damaged wiring, or a problem with the sensor's mounting or calibration.
4. Can a B2298 code damage my car?
While the code itself won’t cause damage, ignoring it may lead to reduced functionality of the rain-sensing wipers, which could impact visibility during rain.
5. How can I fix a B2298 code?
Inspect the rain sensor for physical damage, check wiring connections for shorts or corrosion, and ensure the sensor is properly mounted and calibrated. Replace the sensor if necessary.
6. Where is the rain sensor located in a RAM vehicle?
The rain sensor is usually mounted behind the rearview mirror on the windshield, near the base of the glass.
7. Can I drive with a B2298 code?
Yes, you can drive with a B2298 code, but the rain-sensing wipers may not function properly, so you’ll need to operate the wipers manually in rainy conditions.
8. How do I reset the B2298 code after repairs?
After completing repairs, you can reset the code using an OBDII scanner. If the issue is resolved, the code should not return.
9. How much does it cost to fix a B2298 code?
Repair costs vary depending on the issue, but replacing the rain sensor typically costs between $100 and $300, including parts and labor.
10. Can a B2298 code be triggered by extreme weather?
Yes, extreme heat or prolonged exposure to direct sunlight may cause the rain sensor to overheat, potentially triggering the B2298 code.
