The P1352 code on a Ford indicates a problem with the primary circuit of ignition coil "D".
This issue can cause symptoms such as the "Check Engine" light coming on, engine misfires, and decreased fuel efficiency.
The causes of this problem may include faulty ignition coils, worn-out spark plugs, or malfunctioning fuel injectors.
To fix the issue, diagnosis is required using a code reader, multimeter, and wiring diagram.
The spark plug wires and ignition coil should be inspected, and possibly replaced if necessary.
What does this Code Mean
The P1352 Ford code means there's a problem with your vehicle's ignition system.
It's related to the primary circuit of ignition coil "D". This issue affects engine performance.
You need to find out what's causing the problem. It could be a faulty ignition coil, a wiring issue, or a problem with the powertrain control module (PCM).
Knowing what the P1352 code means helps you diagnose the problem correctly. Then, you can fix it and get your vehicle running smoothly again.
What are the Symptoms
The symptoms that may have led to the P1352 Ford code include:
- The "Check Engine" light is on
- Engine misfires or runs rough
- Vehicle performance is slow or lacks power
What are the Causes
Faulty ignition coils, worn-out spark plugs, or malfunctioning fuel injectors can cause the P1352 Ford code.
These problems disrupt the engine's combustion process. They prevent the fuel-air mixture from igniting correctly, leading to poor engine performance and decreased fuel efficiency.
Other possible causes include:
- Low fuel pressure or a faulty fuel pressure sensor
- A clogged or dirty fuel filter
- A vacuum leak or intake manifold issue
What Tools are Needed to Diagnose
Diagnosing the P1352 Ford code requires specific tools.
You need:
- A code reader or scan tool to get the trouble code and see live data
- A multimeter to measure voltage, resistance, and current in the system
- A wiring diagram or repair manual to understand the electrical system and find potential problems
How to fix Step by Step
Step 1: Locate the ignition coil and spark plug wires.
Step 2: Remove the spark plug wires and inspect them for signs of wear or damage.
Step 3: If you find any issues with the spark plug wires, replace them with new ones.
Step 4: Remove the ignition coil and inspect it for carbon tracking or cracks.
If it's damaged, replace it with a new one.
Step 5: Clear the P1352 code using your OBD-II scanner and test drive the vehicle to ensure the problem is resolved.
What are the Common Diagnosis Mistakes
After replacing the ignition coil and spark plug wires, DIYers and mechanics often still misdiagnose the P1352 code.
Despite fixing what they think is the problem, the code remains, causing frustration and confusion. Misdiagnosis happens due to common mistakes.
Common mistakes to avoid include:
- Not checking the ignition coil boot for wear or damage
- Failing to verify the spark plug gap is set correctly
- Ignoring related trouble codes, such as fuel system or engine mechanical issues
What is the Repair Cost
The cost of repairing a P1352 code can range from $100 to $1,000, depending on the problem.
Diagnosis costs $100 to $200.
Ignition coil replacement is $100 to $300, spark plug wires or boots are $50 to $150, and the entire ignition system can be $1,000.
Can I drive safely with this code?
You can drive short distances if your car is running normally, but it's not recommended.
The P1352 code indicates a problem with your engine's ignition system, which can lead to more serious issues if left unchecked.
