Remember:
• Visual inspections are important!
• Problems with wiring and connectors are common, especially for intermittent faults.
• Mechanical problems (vacuum leaks, binding or sticking linkages, etc.) can make a good sensor look bad to the computer.
• Incorrect information from a sensor may cause the computer to control the engine in the wrong way. Faulty engine operation might even make the computer show a known good sensor as being bad!

Note: Coding runs numerical (1-9) , then HEX values (A-F), followed by numerical values, for example U0001, U0002, U0003 – U0009, U000A, U000B  – U000F, U0010 etc.
This pattern of numerical and HEX follows 10’s and then 100’s so U0099 is followed by U009A which is followed by U009B etc
