Catalytic converter heating phase indicator symbol

Catalytic converter

This is a Catalytic Converter Heating Phase Indicator symbol. It tells the driver that the converter has not yet had time to warm up. We’ve seen this only in Porsche vehicles. Torque is reduced during the heating phase and the symbol goes out as soon as the catalytic converters have reached operating temperature. See your dealer or a good service shop if the light remains on.

  • Otherwise, you can return to our main Manufacturer Symbols pages and scan again!

Remember, the catalytic converter is the first line of defense against pollutants produced by internal combustion engines. Not only does it require being properly warmed up to function properly, it also requires the proper fuel. Keep an eye out for the proper octane rating — cat converters are very pricey to replace.

Cars are changing, and among those changes is the growing number of symbols and indicators that will invariably show up on your dashboard or instrument panel. Every year, new features are added to vehicles, each of which is accompanied by a new symbol or symbols and likely a new abbreviation or acronym.

At DashboardSymbols.com, our aim is to help you understand what is happening to your vehicle at the first sign of trouble — a new warning light illuminated on your instrument panel. Its all here on this website. Our first intention is to bring the latest technologies down to earth and understandable for everyday drivers.
