6.0 GLOSSARY OF TERMS
ABS anti-lock brake system
backfire,
popback
fuel ignites in either the intake or
the exhaust system
CKP crank position sensor
CMP camshaft position sensor
cuts out,
misses
a steady pulsation or the inability of
the engine to maintain a consistent
rpm
DLC data link connector (previously
called engine diagnostic connector)
detona-
tion,
spark
knock
a mild to severe ping, especially un-
der loaded engine conditions
ECT engine coolant temperature sensor
EGR exhaust gas recirculation valve and
system
genera-
tor
previously called alternator
hard
start
The engine takes longer than usual
to start, even though it is able to
crank normally.
hesita-
tion, sag,
stumble
There is a momentary lack of re-
sponse when the throttle is opened.
This can occur at all vehicle speeds.
If it is severe enough, the engine
may stall.
IAT intake/inlet air temperature sensor
IAC idle air control motor
JTEC Combined engine and transmission
control module
lack of
power,
sluggish
The engine has less than expected
power, with little or no increase in
vehicle speed when the throttle is
opened.
LDP leak detection pump
MAP manifold absolute pressure sensor
MIL malfunction indicator lamp
MTV manifold tuning valve
NGC next generation controller
O2S oxygen sensor
PCI programmable communication inter-
face
PCM powertrain control module
PCV positive crankcase ventilation
PEP peripheral expansion port
poor fuel
economy
There is significantly less fuel mile-
age than other vehicles of the same
design ad configuration
rough,
unstable,
or er-
ratic idle
stalling
The engine runs unevenly at idle
and causes the engine to shake if it
is severe enough. The engine idle
rpm may vary (called hunting). This
condition may cause stalling if it is
severe enough.
SBEC single board engine controller
SKIM sentry key immobilizer module
SKIS sentry key immobilizer system
start &
stall
The engine starts but immediately
dies.
surge engine rpm fluctuation without cor-
responding change in throttle posi-
tion sensor
TIP throttle inlet pressure
TPS throttle position sensor
TRS transmission range sensor
VSS vehicle speed sensor/signal
