This feature allows the pressure transducers and harnesses to be interchangeable. Each pressure transducer requires 3 wires: Ground (BLK), Power (+5V DC, RED), and Signal (GRN). The ratio of voltage between power and signal wires is converted into a pressure value. If the signal is above or below the pressure transducers ability to measure it may be because the power wire is not supplying 5V DC or the signal wire is not returning a DC Voltage between 0.5-4.5 VDC. A base code of 57 or 58 is determined based on which PCM connection has the issue, P1 or P2. The expansion codes 01 and 41 explain the type of issue, in this case \u201copen\u201d, meaning the signal wire is returning more than 4.5V DC. The most likely cause of this the sensor wire being disconnected and the PCM board \u201cpulling\u201d up the signal voltage to +5V DC.<\/p>\n\n\n\n<hr class=\"wp-block-separator
