Cat c12 engine fault codes

Cat c12 Fault codes and their meanings. I have replaced the MAF and O2 sensors on my 2009 v6 turbo as part of a performance upgrade. This has caused numerous problems, so I am hoping that some expert can expln why i'm getting all these fault codes. Fault Code C12 - Fuel Injector Control Valve. Fault Description: The injector control valve has a faulty component or is missing. For most Cat products, the code is only one digit, except with the 5 series which usually has two digits, the first being the fault code itself, the second. The second digit is a sequence code which is used to locate the fault. This means that a Cat 5. Cat 5. 3 and others all follow the same rule. 1. 1. For most Cat products, the code is only one digit, except with the 5 series which usually has two digits, the first being the fault code itself, the second. The second digit is a sequence code which is used to locate the fault. This means that a Cat 5. Cat 5. 3 and others all follow the same rule. 1. 1. In this case, it must be related to this code: Cat c12. Check the following items: If your cat 5 product has this code C12, the following may be a cause. Read the descriptions and instructions in each table for more detls on how to properly check each fault. Check for an injector cap or injector vacuum line connection. For more information on the proper way to check a cap. To check a cap, locate the injector on the side of your head (right if your checking left side injectors, left if checking right side injectors). Verify that there is a small circular connection with a cap on it on the injector. If there is not, there is no cap. If there is a cap, check to see that the cap is tightly.

C12

Check to see if you can reach the cap with your hand. If you can reach the cap with your hand, the cap is not properly tightened. If there is no cap on the injector, check the vacuum line to see if there is a cap on it. If there is not, there is no vacuum line connection. If there is a cap on the vacuum line, check that it is tight.

C12

Check for leaks by running your hose and vac. If the hose is loose and can be moved, a leak may be present. If the hose is tight and can't be moved, no leak is present. To find the exact location of a leak, you must connect your cat vac hose to your vac, then attach your hose to your hose test kit, connect your hose test kit to your leak detector and then. Note: Always use the pressure from your vac when testing for leaks. If the leak detector does not detect a leak, check the hoses, clamps, hose fittings and clamps as they may be clogged with dirt or debris.
