Fault codes are recognised problems or faulty sensors to the EMU (Engine Management Unit) which is a ECU (Electronic Control Unit). The ECU relies on the sensors on your car to make it run at it's optimum performance at all times. When a sensors goes wrong or there is a fault with the engine, the ECU sees this problem and logs the fault code within it's memory (NOTE: not ALL problems are logged, depends http://www.topbuzz1.carenthusiasts.co.uk/info/fault_codes/fault_codes.htm on what system your car has). Often the ECU warning light on the dash board may light up, indicating to you that there is a problem. NOTE: The ECU warning lamp usually needs to be on for more than 30 seconds before the ECU logs a fault code. Otherwise it could consider it an intermittent fault and ignore it. Do all ECU's handle fault codes? If your engine is fuel injected then it needs a ECU to control the injection timing. All Vauxhall models that have injection need a ECU to do this and hence they will have the facility to log fault codes. If your engine is run on a carburetor, then it has no ECU, hence no fault codes can be logged or read. How do I read the fault codes? There are two common ways to do this. The first is to use a TECH1 or a TECH2 reader which is an expensive bit of equipment. Some dealerships could charge you £50 just to connect it up to your car. The second option is FREE and YOU can do it....with a paper clip. The paper clip method flashes the ECU warning lamp on the dash, and you read the amount of flashes and pauses. The chart supplied in this article tells you what the fault code means. The paper clip is used to short out two pins in the ALDL connector (also k
