About the Crown

The Crown series was first introduced all the way back in 1955 as the Toyopet Crown. Since that time, there have been a total of 16 generations, far more than most other cars on the roads today. The latest iteration made its debut in 2022.

Interestingly, the model has such prominence in the Toyota lineup that it is one of the few to have its own logo emblazoned on the front and rear fascia. Its crown logo was used to signify the high-end luxury intentions of the model.

The series has seen a huge variety of configurations over the years, but most prominently featured a 4-door luxury sedan layout.

Competition for the model has typically come from the likes of the Nissan Maxima, Lexus GS, and Mercedes C-Class.

One of the most commonly logged fault codes for the model is P0175, which represents a problem with the air-fuel mixture containing too much fuel or not enough air. This code relates specifically to the second bank of the engine, meaning only models from the twelfth generation to the fifteenth generations can have this code logged.

This code can be tricky to solve, usually requiring professional expertise. If there are additional codes logged, they can help pinpoint the cause better.

To make things worse, P0174 is another fairly common code. This code is the inverse of P0175, indicating that the engine is running too lean. Again, this code is for the second bank of the engine, so only a few generations can suffer from it.

Another reportedly common code for the Crown is P0517, which represents a high voltage detected by the battery temperature sensor. In most cases, this simply means the sensor needs to be replaced or that the battery is defective.

However, it is possible for this to result in an overheating condition from the engine. This will almost always be shown by the engine temperature gauge on the dashboard though.
