OBD Code P208E - Reductant Injection Valve Stuck Closed Bank 1 Unit 1

<<See All OBD Codes

Is your Car’s Check Engine Light illuminating on the dashboard? Do you find sudden decrease in the fuel economy? And is the car engine running rough with black smoke coming from tailpipe? This might be the indication of problems with the reductant injection valve of the car which in other words can be an OBD P208E error.


OBD code P209E means Reductant Injection Valve Stuck Closed Bank 1 Unit 1 Issue.

Learn More About OBD Error Code P208E

The P208E code means a fault is present in the reductant injection valve circuit, bank 1 unit 1. The reductant injector is used to reduce emissions gases exiting the exhaust by injecting either air or chemicals depending on the usage and vehicle. When the ECU detects the fault in the reductant injector circuit, it will set the P208E code and the Check Engine Light will be displayed on the dashboard.


What causes this problem with the Reductant Injection Valve Stuck Closed Bank 1 Unit 1?


  • Reductant Injection Valve problematic
  • Reductant Injection Valve circuit wiring and connector issue
  • Reductant Injection Valve circuit problems
  • SCR controller/PCM faults

Replace/Repair These Parts To Fix Code P208E

  1. Engine Control Module – ECM failures and faults can be very difficult to find and resolve as these are very rare and might require a complete reprogramming of the system to avoid wrong codes from getting stored in the system, leading to misdiagnosis. Replace it now!
  2. Powertrain Control Module – Faulty PCM can disrupt the normal functioning of the vehicle by affecting the transmission system and the fuel delivery system. This will cause the system to store wrong OBD error and thus can lead to misdiagnosis.
  3. Diagnostic Tools – Take help of a professional mechanic to diagnose OBD code error. Use high grade diagnostic tools to resolve this issue. Buy new tools and equipment from us!
  4. Fuel Injector – Bad fuel injectors can cause starting issues, poor idles and affected performance. Thus, the replacements are in order. Buy new fuel injectors now!
  5. Exhaust Gas Recirculation Valve - If the PCM detects any fault in the vehicle’s EGR valve circuit, it will set up the check engine light so that the driver is notified about the fault. Properly check for the EGR valve faults leading to this OBD code getting stored in the system. Get the faulty EGR valve replaced or else this fault code can turn up.
  6. Diesel Exhaust Fluid Pump – Faulty DEF pump can lead to increased emission and affected vehicle performance. It can also hamper the fuel economy and the power output of the vehicle. Thus, replace faulty DEF pump now!

Easy Diagnosis Of Engine Error OBD Code P208E

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P208E code to be stored:


  • Take the help of an experienced mechanic who will visually inspecting the exhaust system.
  • Find and freeze frame data with the code. Then, clear the code and take the vehicle on a test drive under the same conditions.
  • If the code reappears, perform a visual inspection of the components and its wiring.
  • If the wiring is okay, the injector itself will be tested to confirm operation.
  • The mechanic will repair or replace faults in relation to the reductant injection air pressure sensor, DEF pump and EGR valve. Also check for any wiring and harness issues and correct the damaged wirings.
  • If there is no problem found, check for the faulty ECU. Although, this fault is very rare but can be a reason for problematic exhaust system, thus hampering the engine performance. The ECU needs to be replaced in such condition and has to be reprogrammed to erase any stored faulty error.

Common Mistakes When Diagnosing the P208E Code


  • Powertrain Control Module (PCM) faulty
  • Reductant injection valve issue
  • Wiring and connector issue
