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.

PREPARATION:
(a) Connect the TOYOTA hand−held tester to the DLC3.
(b) Remove the fuel tank cap.
(c) Disconnect the VSV connector for the vapor pressure
sensor.
(d) Select the ”ACTIVE TEST” mode on the TOYOTA hand−
held tester.
(e) Start the engine.
(f) The VSV for the EVAP is ON by the TOYOTA hand−held
tester and remains on for 5 sec.
CHECK:
Measure voltage between terminals PTNK and E2 of ECM con-
nector 5 sec. after switching VSV for EVAP from ON to OFF.
OK:
Voltage: 2.5 V or less
NG Replace charcoal canister.
