(1 ) With the engine coolant temperature was −40 ˚C( −40 ˚F) or
more but less than 60 ˚C( 140 ˚F) when the engine was started,
and if conditions (a) and (b) are met:
(a) Vehicle has accelerated and decelerated.
(b) Engine coolant temperature remains within 3 ˚C (5.4 ˚F) of
the initial engine coolant temperature (2 trip detection logic)
(2) If the engine coolant temperature is more than 60 ˚C
( 1 40 ˚F) when the engine is started and the vehicle has accel-
erated and decelerated
(3) If the engine coolant temperature sensor records a temper-
ature variation below 1˚C( 1.8 ˚F) successively 6 times (6 trip
detection logic)

INSPECTION PROCEDURE
HINT:
SIf DTCs related to different systems that have terminal E2 as the ground terminal are output simulta-
neously, terminal E2 may have an open circuit.
SRead freeze frame data using the hand−held tester . Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, freeze frame data can help determine if the
vehicle was running or stopped, if the engine was warmed up or not, if the air −fuel ratio was lean or
rich, and other data from the time the malfunction occurred.

BASIC INSPECTION
When the malfunction is not confirmed in the DTC check, troubleshooting should be carried out in all the
possible circuits considered as causes of the problem. In many cases, by carrying out the basic engine check
shown in the following flowchart, the location causing the problem can be found quickly and efficiently. There-
fore, using this check is essential in the engine troubleshooting.
1 CHECK BATTERY VOLTAGE
NOTICE:
Carry out this check with the engine stopped and ignition switch OFF.
