Acronyms and Abbreviations list
I have been continually interrupted in my effort to absorb the valuable information contained on this site by my lack of understanding of the various acronyms and abbreviations used. I found a few partial listings but if a more detailed list exists I didn't find it so decided to make my own.
I thought I’d share with the other rookies. Anyone see any errors or have anything to add? AP = Accelerator Pedal position sensor BARO = Barometric Pressure Sensor CAC = Charge Air Cooler CAC tube= intercooler tube to and from intercooler (cold air charge tube) CEL= Check Engine Light CP3 = High Pressure Injection Fuel Pump. Also known as: IP CMP = Camshaft Position sensor DTC = Diagnostic Trouble Code EBP = Exhaust Back Pressure ECT= engine coolant temp EOC = Engine Oil Cooler. It is situated directly below your engine oil filter, right on top of the engine. EPB sensor= exhaust back pressure sensor EOT = Engine Oil Temperature EPR = Exhaust Back Pressure Regulator, also EBP regulator FICM = Fuel Injection Control Module FPR = Fuel Pressure Regulator FPRV = Fuel Pressure Relief Valve GPC = Glow Plug Control GPL = Glow Plug Light GPM = Glow Plug Monitor HPOP = High Pressure Oil Pump IAT = Intake Air Temperature sensor IC= intercooler IDM = Injector Driver Module IP = see CP3 IPC = ICP= Injection Control Pressure , sensor IPR = Injector Pressure Regulator IVS = Idle Validation Switch LP = Lift Pump. Not used on stock trucks, (performance mod) MM3 = Fuel quantity measured in Cubic Millimeters MAF sensor = Mass Airflow sensor. Not all years have them. MAP = Manifold Absolute Pressure sensor MAT = Manifold Air Temperature sensor MIL = Malfunction Indicator Lamp. "Check Engine" or "Service Engine" light PCM = Powertrain Control Module, also ECU or ECM for Electronic Control Unit or Module PID = Parameter Identification, also Data Stream or Sensor Data MPa = Megapascal. 1 MPa = about 145 PSI PASM =Positive Air Shut off Module STC fitting = snap to connect fitting on 05+ high pressure oil pumps TFT = Trans Fluid Temp V PWR = Battery Voltage |
Great List, Thanks!:pca1:
