Here are the symptoms to look out for:

  • The P208E fault code in an automobile can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include reduced engine power, decreased fuel efficiency, rough idling, stalling, and difficulty starting the engine.
  • Additionally, the vehicle may experience misfires, hesitation, or a lack of acceleration.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

The automobile fault code p208e can be caused by a faulty reductant injection valve, open or shorted harness, or poor electrical connection.

  • The automobile fault code P208E can be caused by a faulty Reductant Injection Valve.
  • It can also be caused by an open or shorted Reductant Injection Valve harness.
  • Additionally, a poor electrical connection in the Reductant Injection Valve circuit can also trigger this fault code.

Below are some possible fixes for the automobile fault code p208e, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p208e, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code P208E can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the repair time, which is commonly charged between $75 and $150 per hour by most auto repair shops. Therefore, the total cost of diagnosis and fixing the P208E fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P208E fault code indicates that the Reductant Injection Valve is stuck closed on Bank 1 Unit 1.

The Reductant Injection Valve is responsible for metering and atomizing the reductant liquid before it is mixed with the exhaust gas. If the temperature sensed by the valve is nearing the maximum temperature threshold, the quantity of reductant spray will be increased to actively cool the valve. The normal operating frequency of the valve is between 3 Hz and .3 Hz.

What are the possible causes of the P208E automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P208E fault code. This code is caused by a faulty reductant injection valve, an open or shorted reductant injection valve harness, or a poor electrical connection in the reductant injection valve circuit. To fix this issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can I visually inspect the wiring harness and connectors related to the Reductant Injection Valve?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light, it could be due to a faulty Reductant Injection Valve or a poor electrical connection. To fix this issue, you should visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. This will help you identify if the Reductant Injection Valve harness is open or shorted, and allow you to take the necessary steps to resolve the issue.

What should I do if I find damaged components or broken, bent, pushed out, or corroded connector’s pins during the inspection of the P208E fault code?

If you find damaged components or broken, bent, pushed out, or corroded connector’s pins during the inspection of the P208E fault code, you should visually inspect the related wiring harness and connectors. Check for any possible causes listed above and ensure that the Reductant Injection Valve circuit has a good electrical connection. This will help to fix the issue and turn off the Engine Light or Service Engine Soon Warning Light.
