Toyota Camry Fault Codes

About the Camry

Sold globally by the Japanese car company Toyota, the Camry started life as a compact car and morphed into a mid-sized vehicle as of 1998.

There were two variations available, a narrow body and a wide body but all were produced with a front engine and a choice of front or four-wheel drive.

Replacing the Toyota Celica Camry, the Camry takes its name from the Japanese word for Crown.

The latest version is referred to as the ‘XV70’ and was unveiled at the North American International Auto Show.

Built upon the GA-K platform, the Camry shares its underpinnings with the Toyota Avalon, Daihatsu Altis, Toyota Crown Crossover, Toyota Harrier, Toyota Venza, Toyota Highlander, Toyota Kluger, Lexus RX, Lexus NX, Lexus ES, Toyota Granvia, Toyota Sienna, Suzuki Across and the Toyota Wildlander.

Some common fault codes are:

• P0420 – A code that represents poor catalyst efficiency; this could mean that the oxygen levels are too low which can lead to problems with either the fuel or exhaust system. This code is often found quickly because the fault attached to it will always illuminate the warning light on the dashboard. There can be a number of causes for this fault code, anything from a damaged exhaust manifold to catalytic oil contamination. Continuing to drive with this problem will continue to cause damage to the catalytic converter which in turn can prove extremely costly.
• P0441 – This fault code displays when a malfunctioning EVAP is detected. This ultimately means that the purge valve is not regulating the fuel vapors correctly, meaning there will either be too much or too little allowed to pass. Usual symptoms that come with this problem include a stronger-than-usual fuel odor and an illumination of the check engine light. The most basic cause of this code will be a missing fuel cap, so this should be checked first. Following this, a defective purge valve should be considered along with a loose EVAP hose and a faulty vacuum switch.
