If you notice the Engine Light ON (or Service Engine Soon Warning Light), it could be a sign of p3473 fault code. Here are the symptoms to look out for:

  • The P3473 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 a decrease in engine performance, rough idling, stalling, or difficulty starting the engine.
  • Additionally, the vehicle may experience reduced fuel efficiency, increased emissions, or a noticeable decrease in power.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

The automobile fault code p3473 can be caused by a variety of factors, including low oil pressure and faulty solenoids.

  • The automobile fault code P3473 can be caused by low oil pressure, restricted oil passage, and engine mechanical condition.
  • It can also be caused by a faulty Cylinder Deactivation Solenoid, an open or shorted Cylinder Deactivation Solenoid harness, and poor electrical connection in the Cylinder Deactivation Solenoid circuit.
  • All of these causes should be considered when diagnosing and fixing the P3473 fault code in an automobile.

Below are some possible fixes for the automobile fault code p3473, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p3473, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for any 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 P3473 diagnosis and fixing cost is influenced by several factors. The estimated repair time for this code is 1.0 hour. The cost of repair is commonly charged between $75 and $150 per hour by most auto repair shops.

These factors play a significant role in determining the overall cost of fixing the P3473 fault code.

It is important to consider these factors when seeking repairs for this issue.

The P3473 code refers to the cylinder deactivation system in the engine. The system deactivates cylinders 1 and 7 on the left bank, and cylinders 4 and 6 on the right bank, switching to a V4 mode. Cylinder deactivation is accomplished by not allowing the intake and exhaust valves to open on the selected cylinders by using special valve lifters.

Switching between V8 and V4 mode is accomplished in less than 250 milliseconds, making the transitions seamless and transparent to the vehicle operator.

The code specifically indicates an issue with cylinder 10 deactivationintake valve control circuito.

What are the possible causes of the P3473 automobile fault code?

If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the P3473 fault code. This code is usually caused by low oil pressure, restricted oil passage, engine mechanical condition, faulty Cylinder Deactivation Solenoid, Cylinder Deactivation Solenoid harness being open or shorted, or Cylinder Deactivation Solenoid circuit having a poor electrical connection. To fix this issue, you should check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components and broken, bent, pushed out, or corroded connector’s pins.

How can I visually inspect the related wiring harness and connectors to fix the P3473 fault code?

To fix the P3473 fault code, start by checking 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 will help you identify any issues with the Cylinder Deactivation Solenoid harness and circuit poor electrical connection.

What are the potential consequences of ignoring the P3473 fault code?

Ignoring the P3473 fault code, which indicates a problem with the Cylinder Deactivation Solenoid, can lead to serious consequences such as reduced fuel efficiency, engine damage, and even engine failure. The cause of the fault code can be due to low oil pressure, restricted oil passage, or a faulty solenoid, among other things. It is important to visually inspect the wiring harness and connectors and check for damaged components to prevent further damage.
