P1359 Mercury Code - Spark Output Circuit Fault
Quick Answer
The P1359 diagnostic trouble code (DTC) for Mercury vehicles refers to a "Spark Output Circuit Fault." This code indicates that there is a problem with the spark output circuit, which is responsible for delivering the high voltage spark to the spark plugs at the correct time to ignite the air-fuel mixture in the engine cylinders. Common causes include Faulty ignition coil, Defective spark plug wires, Worn distributor cap and rotor. 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 P1359 Mercury Description
The P1359 diagnostic trouble code (DTC) for Mercury vehicles refers to a "Spark Output Circuit Fault." This code indicates that there is a problem with the spark output circuit, which is responsible for delivering the high voltage spark to the spark plugs at the correct time to ignite the air-fuel mixture in the engine cylinders. The spark output circuit is an essential component of the ignition system, and any fault in this circuit can lead to misfires, poor engine performance, and potential damage to the engine over time.
Common Causes of P1359 Mercury
- Faulty ignition coil
- Defective spark plug wires
- Worn distributor cap and rotor
- Malfunctioning ignition control module
- Issues with the engine's computer system
Symptoms of P1359 Mercury
- Rough idling
- Hesitation during acceleration
- Engine misfires
- Poor fuel economy
- Stalling
How to Fix P1359 Mercury
- Perform a thorough inspection of the spark output circuit components.
- Test the ignition coil, spark plug wires, distributor cap and rotor, and ignition control module for proper functioning.
- Replace any faulty components identified during the inspection.
- Clear the diagnostic trouble codes and test drive the vehicle to ensure the issue has been resolved.
- If necessary, reprogram the engine's computer system to ensure proper operation.
Cost to Fix P1359 Mercury
The typical repair costs for addressing a P1359 Spark Output Circuit Fault on a Mercury vehicle can range from $200 to $500, including parts and labor. However, it's important to note that specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. Most auto repair shops charge between $80 and $150 per hour for labor, but rates may be higher in metropolitan areas or at dealerships and lower at independent shops. It is recommended to check local rates for a more accurate estimate before proceeding with the repair.

Frequently Asked Questions about P1359 Mercury Code
1. What does the OBDII code P1359 mean for a Mercury vehicle?
P1359 indicates a "Spark Output Circuit Fault," meaning the vehicle's engine control module (ECM) has detected an issue in the ignition system's spark output circuit.
2. What are the common symptoms of the P1359 code on a Mercury?
Symptoms may include difficulty starting the engine, rough idling, misfires, reduced fuel efficiency, and a lack of power during acceleration.
3. What causes the P1359 code to appear on a Mercury?
Common causes include a faulty ignition coil, damaged spark plug wires, a defective ECM, a poor electrical connection in the ignition system, or a short or open circuit in the spark output wiring.
4. Can a faulty spark plug trigger the P1359 code on a Mercury?
While unlikely, a worn or damaged spark plug can contribute to ignition problems. However, the primary cause is typically related to the spark output circuit or ignition coil.
5. How can I diagnose the P1359 code on a Mercury?
Start by inspecting the ignition coil, spark plug wires, and connections for damage or corrosion. Use a multimeter to check for proper voltage in the spark output circuit and scan for additional trouble codes.
6. Is it safe to drive a Mercury with the P1359 code?
Driving with this code is not recommended, as it can lead to misfires, reduced performance, and potential engine damage if not addressed promptly.
7. How do I fix the P1359 code on a Mercury?
Repairs may include replacing a faulty ignition coil, repairing or replacing damaged wiring, cleaning corroded connections, or, in rare cases, replacing the ECM if it's defective.
8. Will clearing the P1359 code fix the issue on my Mercury?
Clearing the code without addressing the underlying issue will only provide a temporary solution. The code will likely return if the root cause is not resolved.
9. How much does it cost to fix the P1359 code on a Mercury?
Repair costs vary depending on the cause. Replacing an ignition coil typically costs $150–$300, while wiring repairs or a new ECM can be more expensive.
10. Can a DIYer fix the P1359 code on a Mercury, or does it require a professional?
A DIYer with basic automotive knowledge and tools can often inspect and replace ignition components. However, diagnosing complex electrical issues may require professional expertise.
