U147E Code - Implausible Data Received From Left Blind Spot Sensor
Quick Answer
The Blind Spot Monitor (BSM) system has two primary components; a Left Blind Spot Sensor (LBSS) and Right Blind Spot Sensor (RBSS). Common causes include Faulty Left Blind Spot Sensor (LBSS), Left Blind Spot Sensor harness is open or shorted, Left Blind Spot Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code U147E Description
The microprocessor analyzes the sensor data to determine whether any detected objects should be reported. When it is determined that an object should be reported, the Sensor controls its respective left or right BSM display directly through a hard-wired output to the Outside Rearview Mirrors. The sensor also sends an electronic request message over the CAN Bus to the radio. The Radio then mutes any current output through the speakers and generates a chime as an audible alert.
Each sensor performs a bulb test by illuminating the triangle icon in the Outside Rearview Mirror at each ignition ON cycle.
The Diagnostic Trouble Code (DTC) will set if incorrect data received from the Left Blind Spot Sensor (LBSS).
What are the Possible Causes of the DTC U147E?
- Faulty Left Blind Spot Sensor (LBSS)
- Left Blind Spot Sensor harness is open or shorted
- Left Blind Spot Sensor circuit poor electrical connection
How to Fix the DTC U147E?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the U147E code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about U147E Code
1. What are the common symptoms of OBDII code U147E?
- Common symptoms include the malfunction indicator light (MIL) illuminating, left blind spot monitoring system failure, and potential loss of left blind spot detection functionality.
2. What causes the OBDII code U147E to trigger?
- The code U147E is triggered when the vehicle's onboard diagnostic system detects implausible data received from the left blind spot sensor. This could be due to sensor malfunctions, wiring issues, or sensor alignment problems.
3. How can I diagnose the cause of OBDII code U147E?
- Diagnosing code U147E typically involves conducting a visual inspection of the left blind spot sensor and its wiring, checking for any physical damage or loose connections. Using a diagnostic scan tool to retrieve additional fault codes and sensor data can also help pinpoint the issue.
4. Is it safe to continue driving with OBDII code U147E present?
- While it may be safe to drive with the code U147E present, it is recommended to address the issue promptly to ensure proper functioning of the left blind spot monitoring system, which enhances overall vehicle safety.
5. Can I repair OBDII code U147E myself?
- Repairing code U147E may require specialized tools and expertise, especially when dealing with sensor calibration or wiring issues. It is recommended to consult a professional mechanic or dealership for proper diagnosis and repair.
6. How much does it typically cost to repair OBDII code U147E?
- The cost of repairing code U147E can vary depending on the underlying cause. Costs may include sensor replacement, wiring repairs, or sensor realignment, with labor costs adding to the total repair bill.
7. Will resetting the fault codes make OBDII code U147E disappear?
- Resetting the fault codes may temporarily clear the MIL, but if the root cause of code U147E is not addressed, the code is likely to reappear once the system detects the same issue again.
8. Can extreme weather conditions trigger OBDII code U147E?
- Extreme weather conditions such as heavy rain, snow, or extreme temperatures can potentially affect the functionality of the blind spot sensor and trigger code U147E. Ensuring the sensor is clean and properly positioned can help mitigate weather-related issues.
9. How important is it to fix OBDII code U147E?
- It is important to address code U147E promptly to ensure the proper operation of the left blind spot monitoring system, which plays a crucial role in enhancing driver awareness and overall vehicle safety.
10. Can a software update resolve OBDII code U147E?
- In some cases, a software update provided by the vehicle manufacturer may address issues related to code U147E by improving sensor calibration or data communication. Check with your dealership or mechanic for software update availability.
