C1145 Jaguar Code - Right Front Wheel Speed Sensor Input Circuit Failure
Quick Answer
The ABS module receives wheel speed readings from each wheel speed sensor and processes this information to determine if an ABS event is necessary. Common causes include Faulty Right Front Wheel Speed Sensor, Right Front Wheel Speed Sensor harness is open or shorted, Right Front Wheel Speed 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 C1145 Jaguar Description
The active wheel speed sensor generates a signal that is sent to the ABS module. The wheel speed sensor circuitry connects to the ABS module through 2 wires and a connector at each wheel speed sensor. When the ignition is turned to the RUN position, the ABS module carries out a self-test by sending a reference voltage to all of the wheel speed sensors through their circuitry to determine if they are functional.
The ABS module continuously monitors and compares the rotational speed of each wheel and when it detects an impending wheel lock, modulates brake pressure to the appropriate brake caliper. This is accomplished by triggering the hydraulic control unit (HCU) to open and close the appropriate solenoid valves. Once the affected wheel returns to normal speed, the ABS module returns the solenoid valves to their normal position and normal (base) braking resumes.
What are the Possible Causes of the DTC C1145 Jaguar?
- Faulty Right Front Wheel Speed Sensor
- Right Front Wheel Speed Sensor harness is open or shorted
- Right Front Wheel Speed Sensor circuit poor electrical connection

Frequently Asked Questions about C1145 Jaguar Code
1. What does the OBDII code C1145 indicate on a Jaguar?
The C1145 code on a Jaguar indicates a malfunction in the Right Front Wheel Speed Sensor Input Circuit, suggesting that the sensor or its circuit is not operating correctly.
2. What are common symptoms of code C1145 in a Jaguar?
Symptoms include the ABS warning light illuminating, decreased anti-lock brake system performance, possible traction control issues, and in some cases, an impact on the vehicle's stability control system.
3. What causes the C1145 code to appear on a Jaguar?
Possible causes include a faulty right front wheel speed sensor, damaged wires or connectors in the sensor circuit, or problems within the ABS module itself.
4. How can I diagnose the C1145 code on my Jaguar?
Diagnosis should start with a visual inspection of the right front wheel speed sensor and its wiring for any obvious damage or disconnections. Following this, using an OBDII scanner and a multimeter can help verify the integrity of the sensor and circuit.
5. What steps are involved in repairing the C1145 code on a Jaguar?
Repair steps typically include replacing the faulty right front wheel speed sensor, repairing or replacing damaged wiring or connectors, and in some cases, repairing or replacing the ABS control module if it is found to be the fault.
6. Can I drive my Jaguar with the C1145 code active?
While you can technically still drive the vehicle, it is not recommended as the ABS and possibly other related systems like traction control may not function properly, which could affect vehicle handling and safety during braking.
7. Is the C1145 code common in Jaguars?
Like many vehicles, Jaguars can experience issues with wheel speed sensors, but whether it is common depends on the model and the environmental conditions the vehicle is exposed to. Regular maintenance can help prevent such issues.
8. What is the cost expectation for fixing a C1145 code on a Jaguar?
The cost can vary widely depending on the specific repair needed. Replacing a wheel speed sensor might cost between $150 and $300, while more extensive wiring repairs or ABS module replacement can increase the cost significantly.
9. Are there any preventive measures to avoid encountering a C1145 code?
Regular maintenance and inspections of the ABS system, including the sensors and their wiring, can help prevent this issue. Keeping the sensor and its vicinity clean from road debris and corrosion can also reduce the risk of failure.
10. How long does it take to fix the C1145 code on a Jaguar?
The time required can vary; simply replacing a sensor might take about an hour, whereas troubleshooting and repairing wiring issues or replacing the ABS module could take several hours depending on the complexity of the fault.
