The personal computer on a Ford recognizes irregularities in the signals produced by the heterogeneous sensors. Provided the expression from these sensors is away of parameter or not there at all, the pc automatically characterizes, identifies and sets it to decree format and stores it in commemoration. The personal computer illuminates the check engine light to inform the Chauffeur of a failure in a action that is under the drag of the machine. These codes are manageable to extract; on the contrary, a code scanner is elementary to bring about so. These are available at most Car parts stores and are not expensive. They are compatible with most vehicles, both Non-native and maid. They Testament come with a decree cross-reference stage that Testament consign a definition of the rule.
Instructions
1. Connect the code scanner plug to the OBD II Harbour, which is under the Ford's Chauffeur's side dash to the left of the steering column. Turn the ignition key to the on position with the engine off.
2. This means that the second oxygen sensor on bank 1 has a failure in its heater circuit, which is used to accelerate the heating of the sensor so that it will go into closed loop faster. Oxygen sensors that are not heated electrically take longer to heat up and begin to operate.4.
Write the codes down and cross-reference them with the code sheet that came with the code scanner. Look up the year and make of the vehicle and all the codes will be listed with their definition. The definition will include the part that is defective or irregular and why it is so. For instance P1460, O2 sensor; B1-S2, heater failure. Push the button on the code scanner marked "Read." The scanner will interrogate the computer and show the code in the window of the scanner. The code is always a letter preceded by a four-digit number For instance, P1465.3.
After the repair is completed, plug in the code scanner again, turn the key on and press the button that says "Erase." This erases the code and turns the check engine light out.
