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 P0001, P0002, P0003 – P0009, P000A, P000B  – P000F, P0010 etc.
This pattern of numerical and HEX follows 10’s and then 100’s so P0099 is followed by P009A which is followed by P009B etc
