How to Fix the P0356 Ford F150 Error Code GuideMechanic.Com The most common cause of the p0356 ford f150 error code is a bad ignition coil.
However, other causes of this error code can be a faulty PCM or short circuit in the ignition system. Below, we’ll look at a few other common causes.
In this article, we’ll explore how to fix these errors and what you should look for in your vehicle. Once you’ve figured out the cause, read on to find a solution for your f150.
How to Fix the P0356 Ford F150 Error Code
Ignition Coil “F” Primary/Second Circuit Malfunction
If your engine is experiencing intermittent misfires, the first thing you should do is check your wiring harness. If the wiring harness is damaged, it will likely need to be replaced.
Another way to determine whether the wiring harness is faulty is to use a digital voltmeter and set it to A/C hertz. Make sure the voltage on the coil pack is between 5 and 20 Hz.
The P0356 code is generated when a primary or secondary wiring circuit is malfunctioning. There are several causes of the code. In the primary circuit, the wires lead from the ECM to the ignition system.
Other causes include a shorted wire or corroded connector. The swap test is a simple method to determine which circuit is in fault.
If your car is displaying this code, the ignition coil may need replacement. If the ignition coil is not functioning correctly, the PCM may log the P0356 error code.
To find out which wiring is malfunctioning, check the resistance of the wires to the ignition coil. In case the resistance of the wires is higher than 10,000 ohms, you’ll need to replace the coil driver switch.
If you’re experiencing vibrations and shaking when you stop your car, a loose ignition coil may be the culprit. Harsh driving and poor maintenance can cause loose connections.
Tightening these connections will help solve the problem. Check the resistance of the ground wire and the coil connector. If there is significant resistance, you probably have an open circuit or a short to ground.
If you’ve got the error code P0356, the next thing you need to do is diagnose it. The code itself is a generic trouble code. Most vehicles manufactured after 1996 use an OBD-II diagnostic tool.
The specifics vary by model, but they all point to the same problem. In many cases, the issue is caused by a different component than the original.
Checking for water intrusion
Despite the fact that Ford has never officially declared a recall for this problem, there are still many ways to check for water intrusion in your F150. One common cause is the rear window seal, which is made of rubber.
While it isn’t an immediate safety issue, you can take your truck in for a service to inspect the seal and see if it’s leaking water. The cost of this repair varies, depending on the extent of the leakage and the location of the leak.
If you notice water coming in beneath the windshield, you may have a leak. This leak is caused by condensation from the evaporator drain tube.
Water can enter your truck through the seal that seals the evaporator. You should have your F150 checked by a service technician if you discover a leak. A leaky radiator seal can be a sign that it’s time to replace your hoses and other parts.
The next step is checking for water intrusion in your Ford F150. If you’re experiencing a hot F150, the cause could be a bad water pump.
If the water leaks from the radiator, it may be the result of a faulty cooling system or a bad water pump. To check for water intrusion, you’ll need to take a few basic steps:

Replacing coil number 6
Replacing coil number six on your Ford F150 is easy if you know a few basic tips. Your truck’s ignition coil is an essential part of the engine and is responsible for generating the spark required to start the engine.
If your coil fails, you’ll probably notice poor gas mileage, hesitation, and even a check engine light. Replacing this part will improve the performance of your vehicle and restore driveability.
To replace coil number six on your Ford F150, you should first determine whether your car is having misfires. The misfire must be more than 2.3% of the firing cycle.
The first step is to use a scanner equipped with Mode 6 capability. They cost around $100 at some online retailers. Otherwise, you’ll have to spend a lot of money to chase down the problem. To ensure you’re replacing the correct coil, you should always check the ignition system.
Before replacing coil number six, make sure you’ve disconnected the ignition system. Then, remove the fuel rails and ignition coil pack. You’ll need these tools.
Then, disconnect the fuses and the ignition coil pack. After that, you can start the work. Once you have the fuses disconnected, you can replace coil number six on your Ford F150. You’ll be glad you did!
Often, a worn coil will cause engine misfires and rough idling. This can also lead to backfires and bucking and jerking.
Eventually, driving a worn-out coil will stress other parts of the engine. Additionally, fuel sucked up in the exhaust system can damage the catalytic converter. This is why it’s vital to replace the coil number six on your Ford F150 as soon as you notice any of these symptoms.
If you notice that one of your coils has failed, you’ll want to replace the entire ignition coil pack. You may need to adjust the timing if you replace it with a new one.
You may also want to check the ignition coils inside the ignition pack. The same applies to the fuel rails. If the ignition coils are still working, you’re good to go. Just make sure to carefully follow the instructions on the ignition coil pack and follow them exactly.
Common causes of p0356
A P0356 code means your car’s ignition system is not working correctly. A short circuit in the wiring harness can cause this problem.
A voltmeter can help you test the voltage at the coil pack. This code is also related to bad PCM. To diagnose the problem, you need to know what the cause of P0356 ford f150 error is. Listed below are some possible causes and what you can do to resolve them.
The cause of P0356 codes can be different for different cars. Some vehicles share the same symptoms and the diagnostic process can vary depending on your make and model.
A maintenance tune up can benefit your vehicle but may not fix the problem. For best results, get a comprehensive diagnosis.
If you suspect your vehicle has a fault code, take your car to a professional mechanic. A mechanic can perform the necessary diagnostics to pinpoint the exact cause of P0356 ford f150.
If you see a P0356 code on your Ford F150, you may have a malfunctioning ignition coil. Ignition coils are responsible for sparking air/fuel mixtures inside the combustion chambers.
They need to work properly, so it’s crucial they work correctly. If your ignition coils are not functioning properly, the PCM is unable to control them. The error code will appear on your dashboard.
