Hardlymoving writes about do-it-yourself automobile maintenance on various makes and models. This article will address the most common error or "fault" codes that trigger the illumination of the "Check Engine" light on the four-cylinder Camry. The PCM controls both the engine and the transmission.

It generates the error codes or fault codes we talk about here. Electrical inputs go to the PCM from sensors located throughout the engine compartment. The PCM processes the inputs in milliseconds and sends electrical signals voltage to electronically controlled valves and relays to make the engine behave in a predictable manner.

When all of these engine control devices are working in harmony with the PCM, the fuel economy, emissions and overall drive-ability of the Camry perform at optimum levels. When the PCM expects electrical input signals from the sensors but doesn't receive them, doesn't receive them fast enough, or doesn't receive them in the voltage range it expects, the PCM generates a fault code and stores it.

The yellow "Check Engine" light comes on to inform the driver of the Camry about the fault. If multiple output sensors fail, the various fault codes will accumulate in the PCM until the problem has been identified and fixed and the fault code s erased. Besides sensor failures, the failure of input control valves and relays which get PCM instruction data via electrical current will generate fault codes as well.

There are both generic and vehicle-specific fault codes.

Vehicle-specific codes are additional codes added by the auto manufacturer to address specific vehicle functions not common with other vehicle makes and models. The fault codes generated by the OBDII only indicate possibilities: a possible problem or set of problems that requires attention. To identify a specific cause, in the absence of some expensive analysis tools, may require component testing as well as trial and error.

Some repair facilities, including dealerships, take the "shotgun" approach—which is to replace every possible item that may have caused the fault code to go on. Their focus is to avoid revisiting the problem and having to deal with you, the customer, more than once.
