of the E11 ECM connector.
Standard:

11CHECK IF DTC OUTPUTS REOCCUR
(a)Clear the DTC. (1)Operating the hand±held tester to erase the codes, or disconnecting the batter\
y terminal or the
EFI and ETCS fuses for 60 seconds or more.
(b)Start the engine and warm it up.
(c)Drive the vehicle around for 10 minutes or more.
(d)Read output DTC using the hand±held tester.
Standard: No DTC output.
HINT:
*: DTCs P0011 or P0012 is output when a foreign object in engine oil is caught in so\
me part of the system.
These codes will stay registered even if the system returns to normal after a\
short time. These foreign objects
are then captured by the oil filter, thus eliminating the source of the problem.

(a)Remove the engine coolant temperature sensor.
(b)Measure the resistance between the terminals.

NOTICE:
In case of checking the engine coolant temperature sensor
in the water, be careful not to allow water to go into the ter-
minals. After checking, dry the sensor.
HINT:
Alternate procedure: Connect an ohmmeter to the installed en-
gine coolant temperature sensor and read the resistance. Use
an infrared thermometer to measure the engine temperature in
the immediate vicinity of the sensor. Compare these values to
the resistance/temperature graph. Change the engine temper-
ature (warm up or allow to cool down) and repeat the test.
