The P202E fault code in automobiles indicates a problem with the Reductant Fluid Injector system. The most common symptom is the illumination of the Engine Light or Service Engine Soon Warning Light. The cause of this issue could be a faulty Reductant Fluid Injector, an open or shorted harness, or a poor electrical connection.

It is important to address this issue promptly as it can lead to increased emissions and reduced fuel efficiency. The repair process involves visually inspecting the wiring harness and connectors for any damage or corrosion. The difficulty level of this repair is moderate, and it typically takes around 1.0 hour to fix.

To interpret the fault code, it is recommended to check the “Possible Causes” listed above and inspect the related components thoroughly.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p202e fault code.

Here are the symptoms to look out for:

  • The P202E fault code in an automobile can cause several symptoms.
  • The most common symptom is the illumination of the engine light or service engine soon warning light.
  • Other symptoms include reduced engine power, poor acceleration, rough idling, stalling, and decreased fuel efficiency.
  • Additionally, the vehicle may experience difficulty starting, and there may be a noticeable decrease in overall performance.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

P202E fault code can be caused by a faulty reductant fluid injector, open or shorted harness, or poor electrical connection.

  • The automobile fault code P202E can be caused by a faulty Reductant Fluid Injector.
  • It can also be caused by an open or shorted Reductant Fluid Injector harness.
  • Additionally, a poor electrical connection in the Reductant Fluid Injector circuit can also trigger this fault code.

To fix the p202e automobile fault code, check the possible causes and inspect the related wiring harness and connectors for any damage.

  • To fix the automobile fault code P202E, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors.
  • Look for damaged components and broken, bent, pushed out, or corroded connector’s pins.
  • Ensure that everything is in good condition.
  • The estimated repair time for this fix is 1.0 hour.

The fault code P202E indicates a problem with the intake manifold runner control circuit. The estimated repair time for this fault code is 1.0 hour. The cost of fixing this issue varies depending on the auto repair shop, but it is common for most shops to charge between $75 and $150 per hour.

Other factors that may influence the cost include the severity of the issue, the type of vehicle, and the location of the repair shop.

The P202E fault code is related to the reductant injection valve circuit in the Selective Catalytic Reduction (SCR) system.

It indicates that there is a range or performance issue with the circuit in Bank 1 Unit 1. This circuit is responsible for injecting a metered amount of Diesel Exhaust Fluid (DEF) into the exhaust gas stream to reduce oxides of nitrogen (NOx) emissions. The Engine Control Module (ECM) uses upstream and downstream NOx sensors to vary the amount of DEF added by varying the reductant injector duty-cycle in response to changes in engine-out NOx levels.

What are the possible causes of the P202E automobile fault code?

If your engine light is on and you’re seeing the P202E fault code, it could be due to a faulty Reductant Fluid Injector, an open or shorted Reductant Fluid Injector harness, or a poor electrical connection in the Reductant Fluid Injector 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 pins.

How can I visually inspect the wiring harness and connectors related to the Reductant Fluid Injector?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light, it could be due to a faulty Reductant Fluid Injector 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 Fluid Injector 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 for the P202E fault code?

If you find damaged components or broken, bent, pushed out, or corroded connector’s pins during the inspection for the P202E fault code, you should visually inspect the related wiring harness and connectors. Check for any possible causes listed above, and make sure to fix any issues with the Reductant Fluid Injector, its harness, or circuit connections.
