CIRCUIT DESCRIPTION
Misfire: The ECM uses the crankshaft position sensor and camshaft position sensor to monitor changes in
the crankshaft rotation for each cylinder.
The ECM counts the number of times the engine speed change rate indicates that misfire has occur-
red.When the misfire rate equals or exceeds the count indicating that the engine condition has deteriorated,
the MIL lights up.
If the misfire rate is high enough and the driving conditions will cause catalyst overheating, the MIL blinks
when misfiring occurs.

P0306For any particular 200 revolutions for engine, misfiring is
detected which can cause catalyst overheating
(This causes MIL to blink)
For any particular 1,000 revolutions of engine, misfiring is de-
tected which causes a deterioration in emission
(2 trip detection logic)
*: Only for 2WD models with a load capacity of 0.5 ton and regular cab.
HINT:
When the 2 or more codes for a misfiring cylinder are recorded repeatedly but no Random Misfire
code is
recorded, it indicates that the misfires were detected and recorded at different times.

REPLACEMENT
1. REPLACE ENGINE COOLANT
(a) Remove the radiator cap.
CAUTION:
To avoid the danger of being burned, do not remove it while
the engine and radiator are still hot, as fluid and steam can
be blown out under pressure.
(b) Drain the coolant from the radiator drain plug and engine
drain plug. (Engine drain plug at the right of engine block.)
(c) Close the drain cock plug.
Torque:Torque (Engine drain plug):
24 N·m (250 kgf·cm, 18 ft·lbf)
2. FILL ENGINE COOLANT
(a) Slowly fill the system with coolant.
Use a good brand of ethylene−glycol base coolant
and mix it according to the manufacturer’s direc-
tions.
Using coolant which includes more than 50 % ethyl-
ene−glycol (but not more than 70 %) is recom-
mended.
NOTICE:
Do not use an alcohol type coolant. The coolant should be
mixed with demineralized water or distilled water.
Capacity (w/ Heater):
8.7 liters (9.2 US qts, 7.7 lmp. qts)
(b) Reinstall the radiator cap.
(c) Warm up the engine and check for leaks.
(d) Recheck the coolant level and refill as necessary.
