Code C1244 Lexus Description
The C1244 diagnostic trouble code (DTC) indicates an issue with the deceleration sensor circuit in Lexus vehicles. The deceleration sensor, also known as the yaw rate sensor or lateral acceleration sensor, plays a crucial role in the vehicle's stability control system. It measures the vehicle's deceleration and lateral movement, providing essential data to the vehicle's electronic control unit (ECU) to help maintain stability during braking and cornering.
Common Causes of C1244 Lexus
- Faulty Deceleration Sensor: The sensor itself may be malfunctioning due to internal failure or wear.
- Wiring Issues: Damaged, frayed, or corroded wiring in the deceleration sensor circuit can lead to open or short circuits.
- Poor Connections: Loose or corroded connectors can interrupt the signal between the sensor and the ECU.
- Moisture Intrusion: Water or moisture entering the sensor or wiring can cause electrical shorts or open circuits.
- ECU Malfunction: In rare cases, a fault within the vehicle's ECU may misinterpret signals from the deceleration sensor.
Symptoms of C1244 Lexus
- Illuminated Warning Lights: The ABS or traction control warning lights may illuminate on the dashboard, indicating a malfunction in the stability control system.
- Loss of Stability Control: The vehicle may exhibit a lack of stability during cornering or emergency braking, leading to potential loss of control.
- Erratic Handling: Drivers may notice unusual handling characteristics, such as oversteering or understeering, especially in slippery conditions.
- Inconsistent Brake Performance: The braking system may feel inconsistent, with the ABS engaging unexpectedly or not at all during braking.
- Diagnostic Trouble Code (DTC) Stored: The C1244 code will be stored in the vehicle's ECU, which can be retrieved using an OBD-II scanner.
How to Fix C1244 Lexus
- Diagnostic Scan: Begin by performing a thorough diagnostic scan to confirm the C1244 code and check for any additional codes that may provide further insight into the issue.
- Visual Inspection: Conduct a visual inspection of the wiring harness and connectors associated with the deceleration sensor for signs of damage, corrosion, or loose connections.
- Sensor Testing: Test the deceleration sensor using a multimeter to check for proper resistance and functionality according to manufacturer specifications.
- Repair or Replace Wiring/Connectors: If any wiring issues or poor connections are found, repair or replace the damaged components to restore proper circuit function.
- Sensor Replacement: If the sensor is determined to be faulty, replace it with a new unit and clear the DTC from the ECU.
Cost to Fix C1244 Lexus
The cost to repair the C1244 code can vary significantly based on the specific issue identified during diagnosis. Generally, the cost for parts and labor can range from $150 to $600. For example, a new deceleration sensor may cost between $100 and $300, while labor costs can vary based on the shop's hourly rate, which typically ranges from $80 to $150 per hour. In metropolitan areas or at dealerships, rates may be higher, while independent shops may offer lower rates. It's advisable to check local rates for a more precise estimate and to consider that diagnostic time may add to the overall cost, typically ranging from 1 to 2 hours depending on the complexity of the issue.
