WHAT ARE YOU EMITTING
THIS IS THE TEMPERATURE THE CYLINDER NEEDS TO REACH FOR NOX TO FORM.
WHAT IS 1360 C
THIS IS THE UNIT OF MEASURE FOR THE MAF
(METRIC)
WHAT IS GRAMS PER SECOND
THIS POTENTIOMETER ON MOST MODERN VEHICLES HAS A REDUNDANT SIGNALS MONITORING THE THROTTLE BLADE
WHAT IS THE THROTTLE POSITION SENSOR (TPS)
THIS IS THE NUMBER OF TWISTED WIRES IN A CAN SYSTEM
WHAT IS 2
THIS PUMP IS USED TO DELIVER FUEL FROM THE TANK AT A PRESSURE OF 40 TO 60 PSI (275 TO 415 KPA) TO THE SECONDARY PUMP
WHAT IS THE LOW PRESURE PUMP
ALTHOUGH THE PRESSURE HASNT CHANGE. THERE IS JUST NOW A HIGHER PRESSURE PUMP.
WITH A SHORT TERM FUEL TRIM AT +25% THE ECM WOULD BE DOING THIS WITH THE FUEL
WHAT IS ADDING FUEL
UNBURNT FUEL IN THE COMBUSTION CHAMBER WOULD CAUSE THIS TO RISE
WHAT ARE HYDROCARBONS
A HOT WIRE GETS COOLED BY THIS AND THAT DETERMINES THE MASS OF AIR ENTERING THE ENGINE
WHAT IS FILTERED AIR
WHEN WATCHING THE 2 SIGNALS OF A TPS THEY SHOULD BE ?
WHAT IS BE OPPOSITE
EACH OF THESE IS 120 OHMS AND IS WIRED IN PARALLEL TO CREATE 60 OHMS OF RESISTANCE
WHAT THE TERMINATING RESISTORS
THIS IS WHERE THE INJECTORS ARE LOCATED AND SPRAY IN A GDI SYSTEM.
WHERE IS THE CYLINDER HEAD.
(COMBUSTION CHAMBER)
WITH A SHORT TERM FUEL TRIM AT -25% YOU COULD SUSPECT THIS IS THE CAUSE
WHAT IS A LEAKING INJECTOR
IF SUNLIGHT IS ADDED TO HYDROCARBONS AND THIS SMOG IS CREATED
NOX (OXIDES OF NITROGEN)
WITH ONE BEING 5 VOLTS AND ANOTHER BEING GROUND THE STAND ALONE MAF USUALLY HAS THIS MANY WIRES
WHAT IS THREE (3)
THIS DUAL POTENTIOMETER SENDS THE DRIVERS REQUEST TO THE PCM
WHAT IS THE ACCELERATOR PEDAL POSITION SENSOR (APP)
AT SPEEDS OF UP TO 500kbps THIS CLASSIFICATION OF CAN IS THE MIDDLE SPEED
WHAT IS CAN C
THE HIGH PRESSURE PUMP RUNS OFF OF THIS ENGINE COMPONENT TO CREATE THE PRESSURE NEEDED.
WHAT IS THE CAMSHAFT
AS THE FUEL TRIM PASSES THROUGH +25% AND STAYS THERE THE MOST LIKELY CAUSE OF THIS WOULD BE THIS
WHAT IS A VACUUM LEAK
(UNMETERED AIR)
A RICH AIR/FUEL MIXTURE WOULD CAUSE THIS EMISSION TO RISE
CARBON MONOXCIDES (CO)
WHAT IS A MFFR
THE RANGE OF THE TPS AND APP VOLTAGE IS TYPICALLY THIS ALL BE IT CAN BE REVERSED
WHAT IS 0 TO 5 VOLTS
OR 5 TO 0 VOLTS
THESE 2 PINS IN THE DLC ARE FOR THE CAN LINE COMMUNICATION WITH A SCAN TOOL AND A GOOD PLACE TO CHECK THE RESISTORS
WHAT ARE PINS 6 AND 14
THIS IS THE TYPICAL IDLE PRESSURE FOR THE HIGH SYSTEM
WHAT IS 300 KPA TO 400 KPA
THIS IS WHEN THE ECM STARTS USING FUEL TRIM PERCENTAGES
WHAT IS CLOSED LOOP
WITH AN IDEAL MIXTURE THIS IS THE DESIRED BY-PRODUCT OF COMBUSTION
CARBON DIOXIDE (CO2)
IF THERE ARE FIVE WIRES AT THE MAF SENSOR THEN THIS SENSOR HAS BEEN ADDED TO IT.
WHAT IS THE IAT
(INTAKE AIR TMEP SENSOR)
FOR THE VOLTAGE TO BE ZERO ON THE SIGNAL WIRE THE RESISTANCE ON THE SYSTEM WILL BE THIS?
WHAT IS HIGH RESISTANCE
STAR AND RING ARE NOT THE TOPOLOGY OF THE CAN BUS SYSTEM BUT THIS ONE IS
WHAT IS LINEAR
THIS IS THE TYPICAL MAX RANGE OF THE HIGH PRESSURE PUMP IS THIS IN KPA
WHAT IS 20 000 KPA
(200 BAR)
(2900 PSI)
THIS IS WHAT HAPPENS TO THE SHORT TERM FUEL TRIM IF A CODE IS SET AND THE ECM GOES INTO OPEN LOOP
WHAT IS RETURNS TO 0%
