DTC P0336 CKP SENSORPFP:23731
DescriptionEBS0121C
The crankshaft position sensor monitors engine speed by means of
signals from the sensing plate (with 56 protrusions) installed to the
fly wheel. The datum signal output is detected 6° signal and sent to
the ECM. The sensor signal is used for fuel injection control and fuel
injection timing control.

Specification data are reference values and are measured between each terminal and ground.
Pulse signal is measured by CONSULT-II.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

GLOW CONTROL SYSTEMPFP:25230
DescriptionEBS0125H
SYSTEM DESCRIPTION
When engine coolant temperature is more than approximately 80°C (176°F), the glow relay turns off.
When coolant temperature is lower than approximately 80°C (176°F):

Ignition switch ON
After ignition switch has turned to ON, the glow relay turns ON for a certain period of time in relation to
engine coolant temperature, allowing current to flow through glow plug.

Cranking
The glow relay turns ON, allowing current to flow through glow plug.

Sta rti ng
After engine has started, current continues to flow through glow plug (after-glow mode) for a certain period
in relation to engine coolant temperature.
The glow indicator lamp turns ON for a certain period of time in relation to engine coolant temperature at the
time glow relay is turned ON.
COMPONENT DESCRIPTION
Glow Plug
The glow plug is provided with a ceramic heating element to obtain a
high-temperature resistance. It glows in response to a signal sent
from the ECM, allowing current to flow through the glow plug via the
glow relay.
