C1244 Code - Open or Short in Deceleration Sensor Circuit

Quick Answer

The skid control Electronic Control Unit (ECU) receives signals from the Yaw Rate and Deceleration sensor via the CAN communication system. Common causes include Faulty Yaw Rate and Deceleration Sensor, Yaw Rate and Deceleration Sensor harness is open or shorted, Yaw Rate and Deceleration 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 C1244 Description

The skid control Electronic Control Unit (ECU) receives signals from the Yaw Rate and Deceleration sensor via the CAN communication system. The yaw rate sensor has a built-in deceleration sensor and detects the vehicle's condition using 2 circuits (GL1: G sensor 1, GL2: G sensor 2). The Engine Control Module (ECM) monitors the Yaw Rate and Deceleration sensor. The ECM sets the OBDII code when the Yaw Rate and Deceleration sensor is not to factory specifications.

Frequently Asked Questions about C1244 Code

1. What does OBDII code C1244 mean?

C1244 indicates an open or short circuit in the deceleration sensor circuit, which monitors vehicle deceleration to assist systems like ABS and traction control.

2. What are the common symptoms of code C1244?

Symptoms include an illuminated ABS or traction control warning light, reduced braking performance, and possible deactivation of stability control systems.

3. What causes code C1244 to appear?

Common causes include a faulty deceleration sensor, damaged wiring or connectors in the sensor circuit, or issues with the ABS control module.

4. Can driving with code C1244 cause further issues?

Yes, driving with this code may compromise the performance of safety systems like ABS and traction control, increasing the risk of accidents in slippery conditions.

5. How can I diagnose code C1244?

Start by inspecting the deceleration sensor and its wiring for damage, checking for loose connections, and using a multimeter to test for continuity or shorts in the circuit.

6. Is a faulty deceleration sensor the only cause of code C1244?

No, other potential causes include corroded electrical connections, short circuits, or a malfunctioning ABS control module.

7. How do I fix code C1244?

Repairs may involve replacing the deceleration sensor, repairing damaged wiring or connectors, or reprogramming or replacing the ABS control module.

8. Can I reset code C1244 without fixing the issue?

While you can clear the code with a scan tool, it will likely return if the underlying problem is not resolved.

9. How much does it cost to fix code C1244?

The cost depends on the specific issue but typically ranges from $100 to $300 for sensor replacement or wiring repairs. ABS module replacement may be more expensive.

10. Can a low battery cause code C1244?

While it's uncommon, a weak or low battery can sometimes cause electrical issues that trigger fault codes, including C1244. Always check the battery voltage during diagnostics.
