Определение ошибки

Код P0355 указывает на то, что блок управления двигателем обнаружил неисправность в цепи катушки зажигания пятого цилиндра двигателя.

Что означает ошибка

Ошибка P0355 Lexus относится к проблемам с катушками зажигания двигателя. Блок управления двигателем управляет и контролирует работу катушек зажигания. Неисправность влияет на работу двигателя.  Как правило, при наличии этой ошибки, мощность мотора падает.

Причины ошибки DTC P0355 Lexus?

Код DTC P0355 регистрируется блоком управления двигателя автомобиля Lexus каждый раз, когда напряжение на катушках зажигания отличается от заводских настроек более чем на 10%. Эта аномалия может быть вызвана неисправной или сломанной катушкой зажигания 5-го цилиндра, коротким замыканием в проводке, не полным контактом на разъёмах или неисправным блоком управления.

Симптомы кода ошибки?

Наличие ошибка P0355 отрицательно сказывается на работе автомобиля, двигатель «троит», наблюдается потеря мощности.

Диагностика ошибки

При диагностике неисправности особое внимание следует уделить цепям между блоком управления и катушкой пятого цилиндра, а также самой катушке. Часто ошибка P0355 появляется из-за проблем с проводкой. Разъёмы и проводка катушки зажигания должны быть тщательно проверены. Если проводку и катушку проверили, то возможно неисправен блок управления двигателем.

Ошибки при диагностике неисправности DTC

Устранить ошибку можно просто выполнив техническое обслуживание автомобиля Lexus. Хотя в качестве возможных причин не следует исключать неисправные компоненты или проводку.

Насколько серьёзна ошибка P0355 Lexus?

Наличие ошибки P0355 может существенно повлиять на ходовые качества автомобиля, особенно это касается резкого ускорения. Устранить причину ошибки необходимо в кратчайшее время, поскольку она чревата внезапной остановкой авто.

Что необходимо ремонтировать при ошибке?

Если при диагностике были обнаружены неисправные компоненты относящиеся к системе зажигания, включая блок управления двигателем, они должны быть отремонтированы или заменены на исправные. Также должны быть устранены все проблемы с проводкой и разъемами в цепи катушки зажигания. Система зажигания должна проверяться ремонта или замены каждого компонента, чтобы правильно определить источник проблемы.

P0355 is a generic OBD II diagnostic code that indicates an issue with the ignition coil “E”. Specifically with the primary or secondary wiring circuits. If your Lexus IS 300 has thrown this code, it may be accompanied by P0305. 

P0355 is a relatively straightforward diagnosis and is typically caused by a bad coil pack or wiring harness issue, although other factors can cause it. We’ll cover the most common ones directly below.

P0355 Symptoms: Lexus IS 300 

• Check Engine Light– The check engine light may be all that you notice when you have this code, particularly if it is caused by an intermittent wiring issue with your IS 300.  
• Misfiring– P0355 might be accompanied by P0305. P0305 indicates a misfire in the fifth cylinder. Resolving P0355 will typically clear P0305 as well. Misfiring can lead to a lack of power and/or engine hesitation. It can also really mess up the catalytic converter.
• Rough Idle– Your vehicle may idle rough if the fifth cylinder isn’t getting enough spark. You very well may smell raw fuel as your IS 300’s engine runs as well.

Understanding Primary and Secondary Wiring

It’s essential to determine if it is the primary or secondary circuit that has thrown the code. Luckily, it’s easy to determine which one is at fault. Use the swap test method listed directly after this section.

Primary

The primary wiring is the wiring harness leading from your IS 300’s ECM/PCM to the ignition system itself. A short, open, or poorly ground wiring harness is almost always what causes P0355 when the primary wiring side has thrown the code. 

Secondary

The secondary side of the equation is the spark side. The spark side is the plugs, plug wires (if so equipped), or the spark plug itself is causing your IS 300 to throw P0355. 

Ignition Coil “E” indicates the problem is in the fifth cylinder. Next, you’ll need to look up which cylinder is number five on your engine. Different manufacturers use different methods. Here’s a pretty good explanation of how how to locate cylinder 5.

P0355 Diagnosis Tip “Swap Test”

There is a straightforward test to determine if the primary or secondary wiring has thrown this code in your IS 300. First, move the ignition components (coil pack, plug wire, plug) from cylinder 5 to another and clear the codes. 

If the code moves from the fifth cylinder, You now know it’s the spark plug, coil pack, or plug itself. You can keep doing this until you lock down the exact cause. For instance, now that we know it has to be one of the components you moved, move them again, but leave one behind. Once the code stops moving with the parts, you know you’ve found the problem.

These are the most common problems that cause P0355:

• Wiring Issues (short, open, or bad ground)
• Bad Coil Pack
• Loose Connection at the coil
• Bad PCM

P0355 Diagnosis: Lexus IS 300

The first goal of diagnosing P0355 is determining if you are dealing with a primary or secondary wiring problem in your IS 300. If you do that, you’ve eliminated half of the variables.  

Voltage Test (Optional, but time-saving)

The first place that you would want to start looking for what could be causing P0355 in your IS 300 would be the wiring harness. You can use a digital voltmeter to check if the coil pack is getting the proper signal. You would want to set it for A/C hertz and check to see if it is between 5-20hz. 

If it was between 5-20hz, it’s doubtful that the coil pack has gone bad. Although, it could be a bad plug or plug wire as well. If it has no signal, it’s time to look at the wiring harness. If you don’t have a voltmeter, you can use the parts swap method to help you determine if it’s the primary or secondary side causing your problems. See directly below ↓.

Parts Swap

A great way to determine if it is an ignition-related component and not a wiring issue is to reset the trouble code and swap the coil, plug, and plug wire (if equipped) with another cylinder. 

If the misfire “jumps” to the cylinder that you’ve just swapped your IS 300’s ignition components into, then you know that what you are looking at is a coil, plug wire, or (most likely) coil pack failure.

If the misfire did move cylinders, you can go ahead and replace the plug, plug wire, and coil pack. If you are on a tight budget, you can keep resetting the code and swap the ignition parts back one at a time until the misfire returns to cylinder 5. Start with the coil pack. The swap method is covered more in-depth in the section above.

Wiring

If the misfire failed to move from the fifth cylinder, then you know that you most likely have an issue with the wiring harness going from the coil pack to your IS 300’s PCM/ECM. 

First, take a look at where the harness plugs into the coil pack. Is it damaged or loose feeling in relation to the other cylinder’s connections? If so, you may need to replace the harness plug and pigtail.

If the misfire is intermittent, jiggle the wiring harness and see if it impacts the way the engine is running. If it does start or stop misfiring, you know you’ve found your problem. 

Look anywhere that the harness bends or touches anything sharp. Look to see if it looks burnt anywhere. Check for damage and repair the wiring accordingly.

Make sure that it has a solid ground.

PCM/ECM

If you still can’t find the problem, it’s time to take a look at the PCM. PCM issues are the least likely answer and an area where it may be time to call in the pros.  

Wrapping Up: P0355 Lexus IS 300

P0355 is usually pretty easy to diagnose through the swap test, even if you don’t have any special diagnostic tools. If there is anything you can add, please leave a comment below. Good luck fixing your IS 300!
