Error Code P0208: What It Means & What To Do?

<<See All OBD Codes

Diagnostic Trouble Code P0208 means that the fuel injector circuit to the cylinder 8 has malfunctioned. This can cause Check Engine Light to illuminate on the dashboard along with lean of rich exhaust conditions with engine misfiring and affected fuel consumption. Thus, it is important to take this problem seriously and solve it at the earliest.

OBD code P0208 is defined as Cylinder 8 Injector Circuit Malfunction. This error code is set by the PCM/ECM if it detects low or high voltage drop or resistance in the fuel injector of cylinder 8. Special transistors, called ‘drivers’ are used by PCM to operate the fuel injector On and Off in the fuel injection system. If it doesn’t see the injector voltage close to battery voltage, i.e. high, it will set P0208 error code. Also, if the PCM notices that the resistance of higher or lower than the expected range for the cylinder 8 fuel injector, the OBD code P0208 error code will set.

What causes the problem of Cylinder 8 Injector Circuit Malfunction?

• Defective or clogged fuel injector
• Open or shorted fuel injector circuit
• Oxygen sensor faulty or failed
• PCM programming error
• Damaged wiring and connectors
• Mass air flow or manifold air pressure sensor failure

1. Fuel Injector - OBD Code P0208 can get stored if the fuel injector is damaged. Thus, replace it immediately.
2. Fuel Pump - Check for leaks and damaged to the fuel pump that causes reduced fuel delivery and hence hampered performance. Replace it now!
3. Powertrain Control Module - Any fault with the Powertrain Control Module can also cause the P0208 code to the flashed. Get it checked and replace if needed. Buy new components form us.
4. Diagnostic Tool - Always use a professional factory grade OBD scanning and testing tools to diagnose the OBD errors. Buy quality tools from us now!
5. Engine Wiring Harness - Check for damaged wiring harness and replace it now! Buy new components form us.
6. Engine Control Module - Damaged ECM components should be replaced as it can directly affect engine performance if it reads wrong data. Buy from us now!
7. Battery & Electrical System - Buy quality battery and electrical components and replace the old ones, if found faulty. Buy from us now!
8. Engine Wiring Harness - Check for damaged wiring harness and replace it now! Buy new components form us.

Following are the symptoms indicative of P0208 error:

Common Symptoms

• Diminished engine performance
• Reduced fuel efficiency
• Lean exhaust codes
• Check Engine Light illuminated
• Engine going to failsafe mode
• Misfire codes may also be stored

It is very important to fix the fault code P0208. So here are some ways with which you can correct this issue:

• Cylinder 8 Fuel Injector Replacement
• Fuel Pump replacement
• Fuel Filter replacement
• Powertrain Control Module repair/replace/reprogram
• Fuel Injection System replacement
• Damaged wirings replacement

Always install a scan tool into the diagnostic link connector (DLC) port of the car and scans for any codes stored in the ECM. Clears all codes and performs a road test to verify the malfunction (if the vehicle can be driven).

• Check for any leaks and address them immediately. This causes lower than desired fuel pressures in any closed system. Rusted lines, fuel filter gaskets, deteriorated O-rings, etc. all cause fuel leaks.
• Next, examine the low fuel pressure system's filter which may be located on the frame rail or close to the fuel tank. Make sure you follow proper bleeding and filter replacement procedures as introducing air into a diesel fuel system can be a tricky problem to rectify. Refer to service manual for specifications and procedures.
• Locate your fuel injector and make sure to ensure no fittings or connectors are leaking fuel. Also, around the injector itself (O-ring) is a common leak. Visually inspect for any signs of physical damage or for that matter anything that would cause fuel flow to be reduced (i.e. kinked line at injector). Particles within the fuel is a real possibility given the openings being so small. Ensure proper fuel system maintenance (e.g. fuel filters, EVAP, etc.)
• Check for wiring and connections in relation to the injector circuit and repair or replace it as necessary. Recheck the output voltage and resistance reading from the injector circuit to confirm it is working properly.
• Check for PCM/ECM faults, if all other components work perfect. Although it is rare for the PCM to be faulty, but replace or reprogram as required.

Common Mistakes When Diagnosing The P0208 Code

Most of the time we tend to diagnose the problem without completely identifying the real cause of it. It is important to follow all the diagnostic steps and examine each component carefully before correcting. Some of the components to be focused on are listed below;

• Clogged fuel filter
• Fuel pressure regulator failure
• Fuel pump failure
• Leaking fuel lines
• Fuel injector failure
• Powertrain Control Module (PCM) failure
• Wiring/harness issue
