C1289 Mercury Code - Pressure Transducer Redundant / Secondary Input Circuit Failure
Quick Answer
The Anti-Lock Brake System (ABS) Module monitors the Pressure Transducer Redundant. Common causes include Faulty Pressure Transducer Redundant, Pressure Transducer Redundant harness is open or shorted, Pressure Transducer Redundant 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.

Frequently Asked Questions about C1289 Mercury Code
1. What does the OBDII code C1289 mean on a Mercury vehicle?
C1289 indicates a fault in the Pressure Transducer Redundant/Secondary Input Circuit, which monitors brake system pressure for proper operation.
2. What are the common symptoms of code C1289 on a Mercury?
Symptoms may include the ABS warning light turning on, reduced braking performance, or inconsistent brake pedal feel.
3. What causes the C1289 code to appear?
Common causes include a faulty brake pressure sensor, damaged wiring or connectors in the pressure transducer circuit, or a malfunctioning ABS module.
4. Can I drive my Mercury with the C1289 code active?
While driving may still be possible, it’s not recommended as the ABS system may not function correctly, increasing the risk of brake failure in emergency situations.
5. How do I diagnose the C1289 code on my Mercury?
Start by inspecting the brake pressure sensor, wiring, and connectors for damage or corrosion. Use a scan tool to verify the fault and test the sensor’s output.
6. How do I fix the C1289 code on a Mercury?
Repairs may include replacing a faulty brake pressure sensor, repairing or replacing damaged wiring, or recalibrating or replacing the ABS module.
7. How much does it cost to repair the C1289 code?
Repair costs vary depending on the issue but may range from $100 to $400 for sensor replacement or wiring repairs. ABS module replacement can cost significantly more.
8. Can a low brake fluid level trigger the C1289 code?
No, a low brake fluid level typically triggers a different code or warning light. However, it’s always a good idea to check fluid levels as part of diagnostics.
9. Will clearing the C1289 code fix the problem?
Clearing the code without addressing the underlying issue will only temporarily turn off the warning light. The code will likely return until the fault is fixed.
10. Does the C1289 code affect the entire braking system?
The code specifically impacts the ABS system and brake pressure monitoring. While basic braking may still work, ABS functionality could be compromised.
