Common 2017 Ford Transit Engine Problems

Several engine-related issues have been reported in the 2017 Ford Transit. Let's dive into some of the most frequent ones:

1. Engine Misfires

Engine misfires are a common complaint among 2017 Ford Transit owners. This occurs when one or more cylinders in the engine fail to fire properly, leading to a rough-running engine, reduced power, and poor fuel economy. You might notice the van shaking or vibrating, especially at idle. The check engine light will likely illuminate, and a diagnostic scan might reveal codes like P0300 (random misfire), P0301 (misfire in cylinder 1), P0302 (misfire in cylinder 2), and so on.

Possible Causes:

• Faulty spark plugs: Spark plugs ignite the air-fuel mixture in the cylinders. Over time, they can wear out or become fouled, leading to misfires. Replacing the spark plugs is often the first step in diagnosing a misfire.
• Ignition coil problems: Each cylinder has an ignition coil that provides the high-voltage spark needed to ignite the fuel. A faulty coil can prevent the spark from occurring, causing a misfire. Testing the ignition coils and replacing any that are bad is crucial.
• Fuel injector issues: Fuel injectors spray fuel into the cylinders. If an injector is clogged or malfunctioning, it can disrupt the fuel supply and cause a misfire. Cleaning or replacing the fuel injectors might be necessary.
• Vacuum leaks: Vacuum leaks can disrupt the air-fuel mixture, leading to misfires. Checking for vacuum leaks around the intake manifold, hoses, and other components is important.
• Low compression: Low compression in a cylinder can also cause misfires. This could be due to worn piston rings, damaged valves, or a blown head gasket. A compression test can help diagnose this issue.

Solutions:

• Replace spark plugs: Start by replacing the spark plugs with the recommended type for your Transit.
• Test and replace ignition coils: Use a multimeter or a specialized tool to test the ignition coils. Replace any faulty coils.
• Clean or replace fuel injectors: You can try cleaning the fuel injectors with a fuel injector cleaner. If that doesn't work, consider replacing them.
• Check for and repair vacuum leaks: Inspect all vacuum lines and connections for leaks. Replace any damaged hoses or fittings.
• Perform a compression test: If the misfire persists, perform a compression test to check for low compression in any of the cylinders.

2. Engine Stalling

Engine stalling can be a frustrating and potentially dangerous problem. It can occur while idling, driving at low speeds, or even at higher speeds. Stalling can be caused by a variety of factors, making it important to diagnose the root cause accurately. This issue definitely needs immediate attention!

Possible Causes:

• Faulty mass airflow (MAF) sensor: The MAF sensor measures the amount of air entering the engine. A faulty sensor can provide incorrect readings to the engine control unit (ECU), leading to stalling.
• Dirty throttle body: A dirty throttle body can restrict airflow to the engine, causing it to stall, especially at idle.
• Failing fuel pump: The fuel pump delivers fuel from the fuel tank to the engine. A failing fuel pump may not provide enough fuel, leading to stalling.
• Crankshaft position sensor (CKP) issues: The CKP sensor monitors the position of the crankshaft. A faulty sensor can disrupt the timing of the engine, causing it to stall.
• Idle air control (IAC) valve malfunction: The IAC valve controls the amount of air that bypasses the throttle plate at idle. A malfunctioning valve can cause the engine to stall at idle.

Solutions:

• Clean or replace the MAF sensor: Try cleaning the MAF sensor with a MAF sensor cleaner. If that doesn't work, replace it.
• Clean the throttle body: Clean the throttle body with a throttle body cleaner. Be sure to follow the instructions on the cleaner carefully.
• Test the fuel pump: Use a fuel pressure gauge to test the fuel pump pressure. If the pressure is low, replace the fuel pump.
• Replace the CKP sensor: If the CKP sensor is faulty, replace it with a new one.
• Replace the IAC valve: If the IAC valve is malfunctioning, replace it with a new one.

3. Loss of Power

Experiencing a loss of power in your 2017 Ford Transit can be concerning, especially when you rely on it for work or transportation. A sudden or gradual decrease in engine power can make it difficult to accelerate, climb hills, or maintain speed. Several factors can contribute to this issue, so it's important to investigate the potential causes.

Possible Causes:

• Clogged fuel filter: A clogged fuel filter can restrict fuel flow to the engine, leading to a loss of power. Replace the fuel filter regularly as part of your maintenance schedule.
• Catalytic converter problems: A clogged or damaged catalytic converter can restrict exhaust flow, reducing engine power.
• Turbocharger issues (if equipped): If your Transit has a turbocharger, problems with the turbo can cause a significant loss of power. This could include a faulty turbocharger, boost leaks, or problems with the turbo control system.
• EGR valve issues: The EGR valve recirculates exhaust gases back into the engine. A malfunctioning EGR valve can cause a loss of power, especially at higher speeds.
• Vacuum leaks: Similar to misfires, vacuum leaks can also contribute to a loss of power by disrupting the air-fuel mixture.

Solutions:

• Replace the fuel filter: Replace the fuel filter with a new one.
• Inspect the catalytic converter: Have the catalytic converter inspected for clogs or damage. If necessary, replace it.
• Inspect the turbocharger (if equipped): Have the turbocharger inspected for damage or leaks. Repair or replace the turbocharger as needed.
• Check the EGR valve: Check the EGR valve for proper operation. Clean or replace it if necessary.
• Check for and repair vacuum leaks: Inspect all vacuum lines and connections for leaks. Replace any damaged hoses or fittings.

4. Check Engine Light

The check engine light is a warning signal that indicates a problem with the engine or related systems. While it can be triggered by a minor issue, it's important to investigate the cause to prevent potential damage or more serious problems. Ignoring the check engine light is never a good idea.

Possible Causes:

• Loose gas cap: A loose gas cap is a common cause of the check engine light. It can cause a pressure imbalance in the fuel system, triggering the light.
• Oxygen sensor problems: Oxygen sensors monitor the amount of oxygen in the exhaust. Faulty sensors can provide incorrect readings to the ECU, triggering the check engine light.
• Catalytic converter issues: As mentioned earlier, problems with the catalytic converter can also trigger the check engine light.
• Evaporative Emission Control System (EVAP) problems: The EVAP system prevents fuel vapors from escaping into the atmosphere. Problems with this system can trigger the check engine light.
• Any of the issues mentioned above: Misfires, stalling, and loss of power can all trigger the check engine light.

Solutions:

• Tighten the gas cap: Make sure the gas cap is properly tightened.
• Get the codes read: Use an OBD-II scanner to read the diagnostic trouble codes (DTCs) stored in the ECU. This will help you pinpoint the cause of the check engine light.
