I don't consider myself a noob but on forums like this when people use shorthand style typing sometimes I don't understand what they mean. like the 3 letter abbreviations
ex. lca= lower control arm and cel= check engine light. along those lines
definitions of any of these types of abbreviations would be appreciated
thanks in advance

 

There are quite a few but some I remember off the top of my head are. a lot of them you can assume from the letters and the topic

VC= Valve Cover
HG=Head Gasket
Dizzy= Distributor
VSS= Vehicle Speed Sensor
FC- Flux Capacitator
IM= Intake MAnifold

 

thanks for those, I do try and assume what they are but alot of it is me not knowing the part name or the full part name so what I try to think it is doesn't make sense

 

Here are just a few I can think of...

TDC Top Dead Center
BDCBottom Dead Center
BTDC Before Top Dead Center
CC Cubic Centimeter
L Liter
mm Millimeter
EWH Engine wire harness
I/M Intake manifold
E/M Exhauust Manifold
WG Wastegate
BOV Blow Off Valve
IC Intercooler
DP DownPipe
SS Stainless Steel
P/S Power Steering
A/C Air Conditioning
AT Automatic Transmission
MT Manual Transmission
ABS Antilock Braking System
SRS Supplemental Restraint System
ECT Engine CoolantTemperature
TPS Throttle Position Sensor
MAP MAnifold Absolute Pressure
IAT Intake Air Temperature
VTEC Variable Valve Timing with Electronic Control
EGT Exhaust Gas Temperature
EGR Exhaust Gas Recirculate
PCV Positive Crankcase Ventilation-----IT IS NOT PVC like plumbing supplies
ECM Engine Control Module- only controls the engine
PCM Powertrain Control Module- Controls Engine and Transmission
OBD On Board Diagnostics Vresions 0,1,2,2a
DTC Diagnostic Trouble Code
ICM Ignition Control Module AKA Igniter
IACV Idle Air Control Valve
EACV Electronic Air Control Valve- functions same as above
DVOM Digital VOlt Ohm Meter
12V Battery voltage
+ Positive voltage
- Ground
IGN Ignition
MIG Metal Inert Gas
TIG Tungsten Inert Gas
POS Positive or Piece of Sh*t
Neg Negative
