Error codes are displayed on the instrument panel while the machine is moving.

They are displayed either with flashing indicators, cuddles, or, on more modern machines, on a digital display. Indicator colors and names may vary depending on the manufacturer, but most often it is yellow, red and green and means a warning, stop, service. Red color STOP must be understood as a stop signal. It indicates the need to turn off the engine at the earliest opportunity and leave it turned off until the fault is rectified. To check the DTCs of the electronic fuel supply system and the engine protection system, turn the diagnostic key to the OFF position and the diagnostic switch to the ON position.

Turn the car key to the ON position. If there are no active DTCs recorded, the yellow and red indicators will not appear. If there are active trouble codes recorded, flashing lights immediately appear. The numbers of the fault codes flash in the following sequence: the warning signal yellow flashes first, highlighting the digit of the fault code.

After a new pause, the warning light returns again. Thus, the change of signals and the digital display of error codes are repeated. When you are finished working with the diagnostic system, return the diagnostic switch to the off position.

This list of faults, also called DTC for Data Trouble Code has been defined so that any diagnostic device can read and decode them.

They have a standard format as shown below:. As the list of generic OBD codes is not always sufficient, manufacturers can add as many of their own codes as they need. The last 3 digits correspond to an incremented number purple digits. This may be a hexadecimal number i. For P family codes, sub-families have been defined using the 1st digit in this example the "3" :.

Below you will find a list of the most commonly used codes. Our software contains all of the 11 codes. Don't hesitate to download it.

Error code Engine: ISF 2. The ECM is not repairable. The ECM detects that the signal inputs of the crankshaft position and camshaft position sensors are connected in reverse order. Possible causes for this DTC are damage to the camshaft position sensor, an open or short circuit in the circuit, or a fault in the power circuit.

Possible causes for this DTC are damage to the crankshaft position sensor, an open circuit or short circuit in the circuit or a malfunction in the power circuit. The ECM determines that the voltage signal of the pressure sensor in the intake manifold exceeds the value specified in the calibration for more than 1 second.

The ECM determines that the voltage signal of the pressure sensor in the intake manifold is less than the value specified in the calibration for more than 1 second. Error code Engine: ISB Error: Intake manifold pressure sensor circuit — the data is accurate, but exceeds the norm. This DTC becomes active when the pressure in the intake manifold exceeds the maximum allowable value for a given engine power rating. Error code Engine: QSB 3. The ECM determines that the accelerator pedal position sensor signal voltage exceeds the value specified in the calibration for more than 1 second.

The ECM detects that the accelerator pedal signal voltage is out of range below normal.

These codes provide information on which systems are malfunctioning, where the problem is located, and the exact issue that is causing your check engine light to remain illuminated. ECU fault codes include a letter followed by four numbers. The first letter either P, B, C, or Uinforms the reader of the system being affected by the problem.

The next digit explains what the ECU trouble code pertains to. The following numbers indicate problems within specific systems or controls within your vehicle. Emission Management Fuel or Air Metering 2. Injector Circuit Fuel or Air Metering 3.

Ignition or Misfire 4. Auxiliary Emission Controls 5. Computer and Output Circuit 7. Transmission 8. Despite the amount of diagnostic trouble codes, some vehicle problems are seen more often than others, causing certain ECU fault codes to be more common. The following ECU fault codes are triggered by commonly seen vehicle errors.

These codes represent problems with engines misfiring. The last two digits specify which engine cylinder is experiencing the misfires, or if the misfires are not contained to one cylinder.

Misfires can occur for many reasons, so it is important to have your car looked at by an auto technician to determine which parts are faulty and in need of a fix.

These codes represent fuel trim trouble. This problem can be caused by leaky valves, dirty sensors or fuel injectors, or low fuel pressure due to pumps or the fuel pressure regulator.

These issues are commonly related to leaks, and experienced technicians can find the exact location of the leak to find the part in need of repair. A catalytic converter code usually is triggered when the converter needs replaced. If your vehicle senses leaking coolant or burning oil, these ECU fault codes will be triggered to indicate that the oxygen sensors have noticed an inefficiency with the catalytic converter.

These oxygen sensor codes are set off with the malfunctioning of the oxygen sensor itself, or with the oxygen heater circuit that heats the O2 sensor upon starting a car. We save you money rebuilding your automotive electronics.

It'll give you a head start, but you'll still have to do some detective work before you start pulling and replacing parts more on this later. And you will find a list of all domestic vehicle lines currently supported by our site. We add manufacturers, and update code lists daily, so be sure to check back often. Engine diagnostic code tool doesn't always have all of the codes preprogrammed into them. Often a scan tool will give you a code number, but not the description of what the code means. For example.

Your scan tool may give you code C for a Ford vehicle ABS fault with no text explaining the code meaning of the problem area. This service allows you to enter your code number to get the code meaning from our huge database of over 15, codes. P U B C Example: Modern vehicles are equipped with onboard computers that monitor the critical systems in your car and warn you when something is going wrong.
