Feel free to use any of these as you wish. I'm sure I will come up with some more as I think about it!
MAP=Manifold Absolute Pressure Sensor (used on speed density cars, not MAF cars)
O2S=oxygen sensor
WB=wide band
AKI=Antiknock Index(what the yellow sticker on the gas pump means.)
(R+M)/2=Average of Road Octane and Motor Octane and is the AKI of gasoline.
CTS=coolant temperature sensor (not a Caddy! )
KS=knock sensor
EFI=electronic fuel injection
MPI=multiport fuel injection
ECU=electronic control unit
PTEC=powertrain electronic control
RAD=radiator
PS=power steering
A/C=air conditioner
A/C COMP=air conditioner compressor
ALT=alternator
WP=water pump
EWP=electric water pump
BAT=battery
ATF=automatic transmission fluid=be sure to use the correct one!
AT=automation transmission
MT or STD=manual transmission
EGR=exhaust gas recirculation
EGT=exhaust gas temperature
CAT=catalytic converter
OHC=overhead cam(s)
OHV=overhead valves
VI or VIS=viscosity index (motor oil)
GND=ground also denoted as COM for common.
TEL=tetraethyllead=old time Ethyl fluid used to raise octane of gasoline and also to protect soft exhaust valve seats on older cars. Extremely poisonous!!! Kills O2Ss and CATs on modern cars. For off road use only.
MIL=malfunction indicator light
PCV=positive crankcase ventilation
DTC=diagnostic trouble code
HC=hydrocarbons
CO=carbon monoxide
NOx--nitrous oxides
SAE=Society of Automotive Engineering (standard sockets)
MET=Metric
WAO=wide ass open (same as WOT in most cases... )
MSD=multiple spark discharge
LED=light emitting diode
O/D or OD=overdrive
CYL=cylinder
CPS=crankshaft position sensor and/or camshaft position sensor
INT=intake
COMP=compression
PWR=power
EXH=exhaust
HID=high intensity discharge
